Which term describes the developmental stage between childhood and adulthood, and what is the charge characteristic of an anion?

• Infancy is the period from birth to about 1 year.
• Childhood follows infancy and precedes adolescence.
• Adolescence is the transitional stage from childhood to adulthood, marked by physical, psychological, and social changes.
• Puberty is the process of physical maturation that occurs during adolescence.
• Teenage refers to the age range (13-19 years) that largely overlaps with adolescence.

Adolescence is the comprehensive term for the developmental stage between childhood and adulthood.
The correct option is A.
$\boxed{\text{A. adolescence.}}$

An anion is an atom or molecule that has gained one or more electrons, resulting in a net negative electrical charge.

Since an anion has gained electrons, it will have more electrons than protons. Conversely, this means it has fewer protons than electrons.

• A. more protons than neutrons: This relates to isotopes, not the charge of an ion.
• B. more protons than electrons: This describes a cation (positively charged ion).
• C. the same number of protons and neutrons: This is not a defining characteristic of an anion.
• D. less protons than electrons: This accurately describes an anion, as it has gained electrons, making the number of electrons greater than the number of protons. The correct option is D. $\boxed{\text{D. less protons than electrons.}}$
