Name the element whose atomicity is
(a)Tetra atomic
(b)diatomic

a

Explanation:

because its measure it

Phosphorus is a tetra atomic element as it always exists as .

Names of Mono and Tetra atomic elements

Explanation:

The total number of atoms present in the molecule is called atomicity.

Based upon atomicity, the molecules are classified as mono atomic, diatomic, triatomic, and poly atomic molecules.

Mono atomic element:

The element which is made up of only one atom, they are called a mono atomic element.

The examples include Sodium, Zinc, Magnesium, Helium, Neon etc.

Tetra atomic element:

The elements which is made up of 4 atoms of same molecules, they are called a tetra atomic element.

Phosphorus is a tetra atomic element as it always exists as .

hope this helps have a nice night❤️

Explanation:

i believe it is 40–40–20%

explanation:

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
