Particles of an Atom Located in the Outermost Shell and Available

Question

Particles of an atom located in the outermost shell and available for chemical bonding are called
A)valence electrons.
B)isotopes.
C)excess electrons.
D)neutrons.

Accepted Answer

Valence electrons are the particles of an atom located in the outermost shell and are available for chemical bonding. Isotopes are atoms of the same element with different numbers of neutrons. Excess electrons are electrons that exceed the number of protons in an atom, leading to a negative charge. Neutrons are particles located in the nucleus of an atom and have a neutral charge.
