Explanation:

Difference between the two:

Atoms are defined as the smallest particle of a chemical element that exists. They are made up of protons, electrons and neutrons. Elements have similar kind of atoms present in them while compounds have different type of elements present in them.

Molecules are formed when two or more atoms of similar or different kinds bond together. For Example: $H_2O,N_2$ etc...

Similarity between the two:

A pure substance is defined as the substance which is formed by same or different type of atoms which are chemically combined in a fixed ratio by mass. Atoms and molecules are considered as pure substances.

An element with the valence electron configuration 4s24p4 would form a monatomic ion with a charge of fill in the blank 5 . In o

nordsb [41]

Answer:

Charge= -2.

Gains two electron into the 4p^4 to become 4p^6.

Explanation:

The element in the periodic table/chart that matches with the valence electron configuration is Selenium with full electron configuration of [Ar] 3d^10 4s^2 4P^4 which is a non-metal that is found in group 4 of the periodic table/chart.

Selenium can receive 2 more electrons on the 4p^4 to give a -2(minus 2) ion that is Se^2-.

Selenium can also loose 2 electron from 4s^2 to give a +2 ion that is Se^2+.

Selenium can also loose 2 electrons from 4s^2 and 2 electrons from 4p^4 to form Se^4+.

Selenium can also loose 2 electrons from 4s^2 and 4 electrons from 4p^4 to form Se^6+.

Thus, in order to form a monatomic ion with a charge(we will be making use of the most stable one). Thus, it will gain two more electron since this is easier to become 4s^2 4p^6.
