Explain why a magnesium atom is smaller than atoms of both sodium and calcium

Chemistry

A magnesium atom is smaller than sodium and calcium atom according to the periodic table trend that tells that elements from left to right and up to down increases in atomic radius. This points out to the valence shell electrons which is related to the atomic radius.

Which cellular change in an organism could be inherited be the next generation?
ikadub [295]

In order for a cellular change to be inherited, this change must be present in the male gamete, or sperm or present in  the female gamete, the egg or ovum. This is due to the fact that a baby is created from the fusion of an egg and sperm. Therefore, choice 2,  the deletion of a single DNA base in a sperm cell of a trout, is the correct answer.  

If we think about it logically, cellular changes in other parts of body should not affect the next generation. For example, if mom has skin cancer, it does not mean at all  that the baby will have it as well.

Identify the state(s) of matter that each property describes.
DIA [1.3K]

Answer:

1) takes the shape of its container ( liquid and gas).

2) fills all available space (gas)

3) maintains its shape ( solid)

4) can be poured ( liquid)

5) is compressible ( gas)

6) has a fixed volume ( liquid and solid)

Explanation:

Matter is simply defined as anything that has weight and occupies space. It exists in three states, namely: solid, liquid and gaseous states.

The properties of different states of matter includes:

SOLID STATE

--> It has a definite shape: The shape of a solid is fixed; it does not depend on the shape of other materials.

--> It has a definite volume: it occupies its own shape due to the force of cohesion among its molecules.

--> It is tightly packed: The molecular movements of particles are negligible.

LIQUID STATE

--> liquid has a defined volume.

--> it has no definite shape: There is no specific shape of a liquid. It occupies any available space. It's shape depends on the shape of the container into which it is poured.

GASEOUS STATE

--> it has no fixed shape: Due to the distance in the molecules of gas, the gaseous state has no shape. It occupies the shape of its container.

--> It has no fixed volume: it occupies the shape of any container that is closed.

--> It is highly compressible: The particles of gas are far off from one another and there is room for collision.
