Question

An atom that has only one electron in its valence electron shell is ________ chemically reactive. A. not B. mildly C. highly D. The name of the element is needed to figure this out.

Answer 1

i think it is b i am not sure

Answer 2

The option C is correct option. And full statement is "An atom that has only one electron in its valence electron shell is highly chemically reactive".

Step-by-step explanation:

• Valence electron means electron in outer shell.
• Reactivity of an atom depends upon the ability to give or take electron from other atoms.
• As above described, this atom has only one electron and to get stability, it will readily give electron to other atom.
• Stability of atom is a state when an atom has filled outer shell.
• Hence to get stable atom will highly reactive towards other atoms.
