What charge does an electron carry?

Back

An electron carries a negative charge.

Front

Where are protons and neutrons located in an atom?

Back

Protons and neutrons are located in the nucleus of an atom.

Front

What is the mass comparison between protons, neutrons, and electrons?

Back

Protons and neutrons have approximately the same mass, which is much greater than that of electrons.

Front

What is the role of electrons in an atom?

Back

Electrons are involved in chemical bonding and determine the atom's reactivity.

Front

What is the nucleus of an atom?

Back

The nucleus is the central part of an atom, containing protons and neutrons.

Front

How do the number of protons in an atom determine its element?

Back

The number of protons (atomic number) defines the identity of an element.

Front

What is an ion?

Back

An ion is an atom that has gained or lost one or more electrons, resulting in a net charge.
