There are five valence electrons in nitrogen atom and they always participate in covalent bond formation.
Atoms participate in;
Ionic bondingCovalent bondingMetallic bondingThe type of bonding that atoms of elements are involved in depends on the number of electrons in the valence shell of each of the bonding atoms.
Recall the elements that have very few electrons in their valence shell(metals) often form ionic bonds with other elements whose valence shell are less than the stable octet by one or two electrons.
On the other hand, nonmetals having more electrons on their valence shell often share electrons in a covalent bond.
Nitrogen is a nonmetal that has five valence electrons. Nitrogen often shares three of these electrons with atoms of other elements in a covalent bond.

How many atoms of nitrogen (N) on in (NH3)3PO4
Answer:
i think 3 but im sorry if im wrong
Explanation:
What are water and carbon dioxide in the cellular respiration reaction? They are reactants because they are present before the reaction. They are reactants because they are present after the reaction. They are products because they are present before the reaction. They are products because they are present after the reaction.
Answer:
They are products because they are present after the reaction.
Explanation:
A chemical reaction refers to any interaction between two or more chemical species that leads to the formation of new chemical species. The species that interacted with each other are called reactants. They were present before the reaction commenced. The species that were formed after the interaction are called products. They only appear after the reaction.
In cellular respiration, carbon dioxide and water appear after the chemical reactions that take place, hence they are products.
Answer:
They are products because they are present after the reaction.

does the ratio of neutrons to protons affect the stability of the nucleus ?
how does the structure of atoms (i.e. protons, neutron, and electrons) affect the electric charge of an object or substance.
Electrons contribute greatly to the atom's charge, as each electron has a negative charge equal to the positive charge of a proton. Scientists define these charges as “+1” and “-1. ” In an uncharged, neutral atom, the number of electrons orbiting the nucleus is equal to the number of protons inside the nucleus.:
Which event is an example of melting?
A. Wet clothes are drying on a clothesline.
B. The outside of a glass of ice water becomes moist.
C. Water drips from an icicle on the edge of a roof.
D. Fog forms in a valley.
SUBMIT
Answer:
C is your correct answer
Answer:
C. Water drips from an icicle on the edge of a roof.
Explanation:
Water dripping form an icicle on the edge of a roof is a clear cut example of melting event.
Melting is a phase change from solid to liquid. It usually occurs when the solid body gains more thermal energy.
Icicles are frozen water; They have a solid stateWhen this ice body melts, drips of water begins to form. We term this melting.Which of these processes occur when water changes to ice?
Is the following equation balanced? Why or why not?
2H2 +02 → 2H,0
Answer:
Yes
Explanation:
It is balanced because On both sides there are 4 hydrogen atoms and 2 oxygen atoms, or in this case, 2 molecular hydrogens and 1 molecular oxygen, which made hydric acid, aka dihydrogen monoxide, or universally, as water.
Some power plants burn coal to produce electricity. The energy released from coal being burned is used to change water into steam. The steam spins turbines of large generators that produce electricity. Which energy transformations occur when coal is used to produce electricity?
Answer:
Steam thus released transforms heat energy from burning coal into mechanical energy that in turn spins the turbine engine. The kinetic energy of the spinning turbine does work in a generator and then the generator that turns this work into electric energy.

What conclusion can you draw about the ability of metals to hold on to and attract electrons, as
compared to nonmetals?
Answer:
Metals react by losing electrons. So, there is high reactivity due to lower attraction. Non-metals react by gaining electrons. So, there is high reactivity due to higher attraction.
Explanation:
Metals react by losing electrons. So, there is high reactivity due to lower attraction. Non-metals react by gaining electrons. So, there is high reactivity due to higher attraction. Also, electrons lost by metals transfer to the nonmetals. It is easier for the metals to lose their valance electrons and form cations rather than gaining electrons.
Metals do not hold on to or attract electrons while nonmetals hold on to or attract electrons.
In the periodic table, metals are found towards the left hand side of the table while nonmetals are found towards the right hand side of the table.
Electron affinity of elements increase from left to right across the period. Electron affinity refers to the ability of elements to attract or hold electrons. This ability increase steadily across the period.
Usually, the electron affinity values of nonmetals are very high showing that they easily hold on to and attract electrons while the electron affinity values of metals is very low showing that they do not easily hold on to and attract electrons.

The boiling point of water is 100.0*C, yet a student measured it to be 101.3*C. Calculate the percent error of the student's measurement.
Answer:
Percent error = 1.3%
Explanation:
Given data:
Actual value of boiling point = 100.0 °C
Measured value = 101.3 °C
Percent error = ?
Solution:
Formula:
Percent error = ( Measured value - Actual value / Actual value ) × 100
Now we will put the values in formula.
Percent error = 101.3 °C - 100.0 °C / 100.0 °C × 100
Percent error = 1.3 °C / 100.0 °C × 100
Percent error = 0.013 × 100
Percent error = 1.3%
Thus, percent error is 1.3.
what is the environmental effect of 3NaCl
Answer:
Sodium and chloride ions separate when salts are dissolved in water. The dissolved sodium and chloride ions, in high concentrations, can displace other mineral nutrients in the soil. Plants then absorb the chlorine and sodium instead of needed plant nutrients such as potassium and phosphorus, leading to deficiencies.

Explanation:
The volume of a sample of gas measured at 27 °C is 10.0 dm . What is the temperature when the volume is reduced to 9.0 dm at the same pressure?
The second temperature of the sample of gas is 24.3°C
The calculation can be done as follows
T1= 27 °c
T2= ?
V1= 10 dm
V2= 9 dm
V1/T1= V2/T2
10/27= 9/T2
Cross multiply
10 ×T2= 9 × 27
T2= 9 × 27/10
= 243/10
= 24.3 °C
Hence the second temperature is 24.3°C
