How are ions formed?
(a)- Ions are formed when neutral atom gains or lose electrons to become positively or negatively charged
(b)- Ions are formed when two atoms join together
(c)- Ions are formed when neutral atom gains or lose protons to become positively or negatively charged
(d)- Ions are formed when two atoms break apart
(e)- Ions are formed when the outer energy shell of an atom is filled.
Answer: a) Ions are formed when neutral atom gains or lose electrons to become positively or negatively charged.
ion is a chemical element that forms the basis of a number of important substances, including water and nearly all other compounds. It is composed of two isotopes: one with energy levels similar to the second with a slightly higher energy. The ratio between these two isotopes determines the properties of matter.
