Atoms Intro

Front

What subatomic particle determines the charge of an atom?

Back

Electrons determine the charge of an atom.

Front

What is the role of neutrons in an atom?

Back

Neutrons contribute to the stability of the nucleus and affect the mass of the atom.

Front

How many protons are in a Hydrogen atom?

Back

A Hydrogen atom has 1 proton.

Front

Where are protons located in an atom?

Back

Protons are located in the nucleus of an atom.

Front

What happens to the mass and charge of an atom when protons are changed?

Back

Changing protons alters both the mass and the charge of the atom.

Front

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom.

Front

What is the difference between an atom and an ion?

Back

An atom is neutral, while an ion has a net charge due to the loss or gain of electrons.

Front

What is the mass number of an atom?

Back

The mass number is the total number of protons and neutrons in the nucleus.

Front

How do isotopes of an element differ?

Back

Isotopes of an element have the same number of protons but different numbers of neutrons.

Front

What is the significance of the electron configuration of an atom?

Back

Electron configuration determines how an atom interacts and bonds with other atoms.
