Answer:

when atoms form ions ,they Usually loss or gain enough electrons to achieve the electron Configuration of a noble gas .

Metal atoms loss electrons while non Metal atoms gain electrons .

When atoms form ions, they usually loose or gain enough electrons to achieve the electronic configuration of a noble gas. Metal atoms loose electrons while nonmetal atoms gain electrons.

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

Answer:

Explanation:

Weight

A measure of the force of gravity on an object

Mass

The measurement of how much matter an object contains

Volume

The amount of space that matter occupies

Density

The physical property that relates the mass and volume of an object or material

Unlike weight, mass doesn't change with location, even when the force of gravity on an object changes

Why do scientists prefer to describe its matter by its mass rather than its weight?

International System of Units

What system of units do scientists use to measure the properties of matter?

Liter, milliliter, cubic centimeter

3 common units of volume

Volume= length•width•height

Volume formula

Sand and feathers have different densities

Why does a kg of sand take up much less space than a kg of feathers?

Density=mass/volume

Density formula

Objects with densities greater than water will sink and objects with densities less than water will float. The density of wood is less than water (1 g/cm3) and the density of iron is greater than water (1 g/cm3)

If you drop a block of iron and block of wood into water, the iron sinks and the wood floats. What can you conclude about the density of iron and wood compared to the density of water?

V=2,400 cm3

A box has a length of 25 cm, a width of 8 cm, and a height of 12 cm. What is its volume?

D= 13.5 g/cm3

A sample of metal has a mass of 94.5 g and a volume of 7 cm3. What is its density?

Mass= density•volume

Mass formula

M= 234.26 g

Corn oil has a density of 6.89 g/cm3. What is the mass of 34.0 cm3 of corn oil?

Yes. No. The pull of gravity is different on the moon.

A solid has a mass of 180. Would the solid have a mass of 180 g on the moon? Would it have the same weight on Earth as on the moon? Explain.

No, because only the mass and volume will change

Will every solid with the same dimensions have the same density?

Grams and kilograms

Common units for mass

Grams per cubic centimeter or grams per cubic milliliter

Common units for density

V= 20 ml

D= 0.75 g/cm3

Answer: The oldest stars are found on the top right on the HR diagram. Hope this helps!

The oldest stars on the Hertzsprung-Russell (HR) diagram are located in the lower-right region known as the main sequence turnoff, the stars in the universe can se seen and studied in several ways.

The main sequence turnoff represents the point where stars begin to leave the main sequence and enter different stages of evolution. The position of the turnoff depends on the age of the stellar population being observed. Older stellar populations, such as globular clusters or the halo stars of a galaxy, have turnoffs located at lower luminosities and cooler temperatures.

Significant figures:

The given measurement have four significant figures 1234.

All non-zero digits are consider significant figures like 1, 2, 3, 4, 5, 6, 7, 8, 9.

Leading zeros are not consider as a significant figures. e.g. 0.03 in this number only one significant figure present which is 3.

Zero between the non zero digits are consider significant like 104 consist of three significant figures.

The zeros at the right side when decimal point is present e.g 2400. are also significant. There are four significant figures are present.

a) 0.003 L

This measurement have 1 significant figure which is 3.

Answer:

One type of evidence that strongly supported the Theory of Continental Drift is the fossil record. Fossils of similar types of plants and animals in rocks of a similar age have been found on the shores of different continents, suggesting that the continents were once joined.

Explanation:

Students were asked to describe evidence of Plate Tectonic Theory.

descriptions listed above accurately describe evidence supporting Plate

Tectonic Theory. Student 3 describes "glacial evidence indicates that different continents were once connected near the South Pole."

The widely recognized scientific hypothesis known as plate tectonics states that the Earth's lithosphere was made up of many major tectonic plates that have already been gently migrating since around 3.4 billion years ago.

The south pole would be one of two locations on Earth's surface at which the planet's axis of rotation crosses it. It is often referred to as one of the Geographic south pole, Terrestrial South Pole, and 90th Parallel South.

The fossil record is such sort of evidence that has been used to support the Claim of Continental Drift. On the coastlines of many continents, fossils of specific kinds of plants, as well as animals have been discovered in rocks that are comparable in age, indicating that the continents had been connected.
