Explanation: Atomic numbers never change, they stay the same which is why they are what elements are identified by
A negativley charged ion is the answer
Answer:Chemical properties such as its ability to form chemical bonds
Explanation:
The group to which an element belong is known by the number of electrons on its outermost shell. Since chemical reactions often involve valence electrons of an atom, the number of outermost shell electrons give us an idea of the chemical properties, reactivity and readiness of the element to form chemical bonds. The number of electrons in the outermost shell is the most succinct description of the chemical disposition of any atom.
