Cation/Anion Practice

Front

What is a cation?

Back

A cation is a positively charged ion that has lost one or more electrons.

Front

What is an anion?

Back

An anion is a negatively charged ion that has gained one or more electrons.

Front

What determines the atomic number of an element?

Back

The atomic number of an element is determined by the number of protons in its nucleus.

Front

How do you calculate the charge of an ion?

Back

The charge of an ion is calculated by subtracting the number of electrons from the number of protons.

Front

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

Back

The charge is neutral (0) because the number of protons equals the number of electrons.

Front

If an atom has 103 protons and 104 electrons, what is its charge?

Back

The charge is -1, making it an anion.

Front

What is the result of adding a positive number to a negative number?

Back

The result depends on the absolute values; if the positive number is larger, the result is positive, and if the negative number is larger, the result is negative.

Front

What is the result of 5 + -7?

Back

The result is -2.

Front

What is the result of 3 + -6?

Back

The result is -3.

Front

What is the significance of neutrons in an atom?

Back

Neutrons contribute to the atomic mass and stability of the nucleus but do not affect the charge.
