Atomic Structure

Front

What is an isotope?

Back

An isotope is a variant of an element that has the same number of protons but a different number of neutrons, resulting in a different atomic mass.

Front

What changes in the atomic structure when an atom becomes an ion?

Back

The number of electrons changes when an atom becomes an ion.

Front

What does the charge of an ion indicate?

Back

The charge of an ion indicates the difference between the number of protons and electrons in the atom.

Front

In a positive ion, do you have more protons or electrons?

Back

In a positive ion, there are more protons than electrons.

Front

What part of an atom is used to identify it?

Back

The number of protons in an atom is used to identify it.

Front

What is the atomic number?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

What is a neutral atom?

Back

A neutral atom has an equal number of protons and electrons, resulting in no overall charge.

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

How do you determine the mass number of an atom?

Back

The mass number of an atom is determined by adding the number of protons and neutrons in the nucleus.
