Question

Amongst the electrons revolving around the nucleus, which electrons
i) Determine the chemical properties of elements
ii) do not determine the chemical properties of an element? Give a reason for your answer. An atom has one electron more than the noble gas configuration.
3)What type of ion would it tend to form? Write the electronic configuration of the ion formed.

Answer 1

Answer:

I).Chemical properties of each element are determined by the element's electronic configuration, and particularly by its outermost valence electrons.

II). It would tend to form a cation.

III). Ions are formed when atoms lose or gain electrons in order to fulfill the octet rule and have full outer valence electron shells. When they lose electrons, they become positively charged and are named cations. When they gain electrons, they are negatively charged and are named anions.
