2-1 Flashcardizz Part 6 Atoms vs. Ions

Front

What is a CATION?

Back

A cation is a positively charged ion that has more protons (p+) than electrons (e-).

Front

What is an ANION?

Back

An anion is a negatively charged ion that has more electrons (e-) than protons (p+).

Front

What defines an ATOM?

Back

An atom is defined as a particle that has an equal number of protons (p+) and electrons (e-).

Front

How do you represent a magnesium ion with 12 protons, 12 neutrons, and 10 electrons?

Back

It is represented as Mg⁺².

Front

What happens to the charge of an atom when it loses an electron?

Back

When an atom loses an electron, it becomes a cation and has a positive charge.

Front

What happens to the charge of an atom when it gains an electron?

Back

When an atom gains an electron, it becomes an anion and has a negative charge.

Front

What is the charge of an atom with 8 protons and 10 electrons?

Back

The charge is -2, making it an anion.

Front

What is the charge of an atom with 6 protons and 4 electrons?

Back

The charge is +2, making it a cation.

Front

What is the relationship between protons and electrons in a neutral atom?

Back

In a neutral atom, the number of protons (p+) equals the number of electrons (e-).

Front

What does the term 'ion' refer to?

Back

An ion refers to an atom or molecule that has a net electrical charge due to the loss or gain of one or more electrons.
