Answer:
Pd (palladium).
Explanation:
46 electrons total, this is representative of the Pd (palladium) element.
Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Palladium (Pd) element is represented by the ground state electronic configuration.
What is element?Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.
The ground state electronic configuration of 1s² 2s² 2p⁶3s² 3p⁶4s² 3d¹⁰ 4p⁶ 5s² 4d⁸ shows total 46 electrons. The element with atomic number 46 is palladium, Pd. Palladium is a d block element. Palladium is found in group 8 and period four of periodic table.

Nuclear fusion reactions release more energy than fission reactions while also generating less waste. However, nuclear fusion reactors are not currently used to generate electricity.
What is the main reason for this?
Nuclear fusion reactions release high energy and required tremendous temperature of nuclear reactors is the main reason for not used to generate electricity.
What are nuclear reactions?Nuclear reactions are those reactions which are taking place in the nucleus of any unstable atom and produces energy.
As in the question it is given that nuclear fusion reactions releases more energy and less wastage, but this energy are releases in the tremendous amount which can be proved harmful for the environment and the humans. To carry out this reaction we have to maintain the very high temperature of nuclear reactors of about 6 times greater than sun's temperature, which is not possible manually.
Hence, high temperature of nuclear reactors and high amount of energy released is the main reason.

True or False. It is reasonable to assume that an atom with a positive oxidation number could make a chemical bond with an atom having negative oxidation number. And why?
A loss of negatively-charged electrons corresponds to an increase in oxidation number, while a gain of electrons corresponds to a decrease in oxidation number. Therefore, the element or ion that is oxidized undergoes an increase in oxidation number.

A green pea plant (Gg) is crossed with a yellow pea plant (gg). What is the probability that the offspring will be heterozygous?
A.25%
B.50%
C.75%
D.100%
Answer:
50 percent
Explanation:
G g
g Gg gg
g Gg gg
since one of the plants are already heterozygous, only half will be heterozygous since the other plant is homzygous
There is 50% probability that the offspring will be heterozygous.
What is heterozygous?At a given gene locus, the existence of two different alleles. One normal allele and one mutant allele, or two separate mutated alleles, can make up a heterozygous genotype (compound heterozygote).
what is allele?An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome.
so, if green pea plant (Gg) is crossed with a yellow pea plant (gg), there will be 50% probability that the offspring will be heterozygous, we can find it by making punnett square so here is the solution

How do we get heat from the sun?
Answer:
When the Sun's energy moves through space, it reaches Earth's atmosphere and finally the surface. This radiant solar energy warms the atmosphere and becomes heat energy. This heat energy is transferred throughout the planet's systems in three ways: by radiation, conduction, and convection.
Explanation:
Answer:
The sun radiates energy in all directions. Most of it dissipates into space, but the tiny fraction of the sun's energy that reaches Earth is enough to heat the planet and drive the global weather system by warming the atmosphere and oceans. The delicate balance between the amount of heat Earth receives from the sun and the heat that Earth radiates back into space makes it possible for the planet to sustain life.

What happens in this circuit if one of the light bulb burns out?
1. Both light bulbs will stop glowing
2. The other light bulb will stay on but get dimmer
3. the other light bulb will stay on and glow more brightly
4. the battery will lose its charge and stop working
Answer:
option 3
Explanation:
it is so because when both bulbs were there It took more electricity to charge both of them. now since only one is there it takes the power that is produced which made the other bulb glow and uses it for itself.

Which statement best compares potential and kinetic energy?
Objects always have more potential energy than kinetic energy.
Kinetic energy increases and potential energy decreases when the velocity of an object increases.
Only potential energy decreases when an object’s height increases.
Objects always have more kinetic energy than potential energy.
Answer:
Its B) Kinetic energy increases and potential energy decreases when the velocity of an object increases.
Explanation:
because i took the test on edge 2020
Taking into account the definition of kinetic, potencial and mechanical energy, the tatement that best compares potential and kinetic energy is: Kinetic energy increases and potential energy decreases when the velocity of an object increases.
Kinetic energyKinetic energy is a form of energy. It is defined as the energy associated with bodies that are in motion.
Kinetic energy is defined as the amount of work necessary to accelerate a body of a given mass and at rest, until it reaches a given speed. Once this point is reached, the amount of accumulated kinetic energy will remain the same unless there is a change in speed or the body returns to its state of rest by applying a force.
The kinetic energy is represented by the following expression:
Ec= ½ mv²
Where:
Ec is the kinetic energy, which is measured in Joules (J).m is the mass measured in kilograms (kg). v is the speed measured in meters over seconds (m/s).Potential energyPotential energy is the energy that measures the ability of a system to perform work based on its position.
Gravitational potential energy is the energy associated with the gravitational force. This will depend on the relative height of an object to some reference point, the mass, and the force of gravity as follow:
Ep= m×g×h
Where:
Ep is the potential energy in joules (J).m is the mass in kilograms (kg).h is the height in meters (m).g is the acceleration of fall in m/s² (approximately 9.81 m/s²).Mechanical energyFinally, mechanical energy is that which a body or a system obtains as a result of the speed of its movement or its specific position, and which is capable of producing mechanical work. Then:
Potential energy + kinetic energy = total mechanical energy
Principle of conservation of mechanical energyThe principle of conservation of mechanical energy indicates that the mechanical energy of a body remains constant when all the forces acting on it are conservative (a force is conservative when the work it does on a body depends only on the initial and final points and not the path taken to get from one to the other.)
Therefore, if the potential energy decreases, the kinetic energy will increase. In the same way, if the kinetics decreases, the potential energy will increase.
Statement best compares potential and kinetic energyTaking into account the definition of kinetic energy, when the velocity of an object increases the kinetic energy increases.
Therefore, considering the principle of conservation of mechanical energy, the potential energy decreases.
So, the correct answer is the second option: Kinetic energy increases and potential energy decreases when the velocity of an object increases.
