Which properties increase when moving down a group of the periodic table?

Chemistry

Dvinal [7]4 years ago

Explanation:

When we move down a group then there will be increase in number of shells present in an atom. Due to this there will be increase in atomic radii of the atom.

As a result, there will be increase in atomic mass of the atom also. Whereas reactivity of metals increases on moving down the group as the valence shell moves away from the nucleus. So, it becomes easy for the metal atom to lose an electron.

On the other hand, reactivity of non-metals decreases on moving down the group.

So, we can conclude that properties increase when moving down a group of the periodic table are atomic radii and atomic mass.

Atomic Mass.

Reactivity decreases as you go down a group.

Atomic Radius also decreases as you go down a group.

Valence electrons are the same within a group.

Atomic mass, however, increases as you go down a group.

Hope this helps!

Describe the effect of subjecting hydrogen to pressure​
ExtremeBDS [4]

Answer:

When hydrogen is subjected to large enough pressure, it solidifies according to theory.

Explanation:

According to theory, when  hydrogen molecules are subjected to enormous degree of pressure the molecules will solidify.

What happens here is that the hydrogen–hydrogen bonds in the hydrogen molecule will break apart and the molecules collapses into hydrogen atoms.

Hence, when hydrogen is subjected to large enough pressure, it solidifies according to theory.

Bonds between metals and nonmetals tend to be ionic, but bonds between nonmetal atoms tend to be covalent. Explain why this is t
Assoli18 [71]
Ionic bond is a type of bond in which one or more atoms are transferred to another atom which results to two ions with opposite charge. They attract each other.

The atom of another element is removed and then gained by another element which produces a noble gas electron configuration.

Covalent bond is a type of bond in which a pair or more electrons are being shared by the atoms of two elements.

Because of this, the molecules become stable by sharing the electrons thus creating a noble gas configuration for each of the atom.
