Neutral Atoms, Ions, and Isotopes

Front

What is a neutral atom?

Back

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

Front

What happens to an atom when it loses an electron?

Back

When an atom loses an electron, it becomes a positive ion because it has more protons than electrons.

Front

What is an ion?

Back

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

Front

What is an isotope?

Back

An isotope is a variant of a chemical element that has the same number of protons but a different number of neutrons.

Front

What is the charge of a negative ion?

Back

A negative ion has a net negative charge because it has more electrons than protons.

Front

What is the atomic structure of Helium?

Back

A neutral atom of Helium has 2 protons, 2 neutrons, and 2 electrons.

Front

What is Carbon-14?

Back

Carbon-14 is an isotope of carbon that has 6 protons and 8 neutrons.

Front

What does the term 'electron cloud' refer to?

Back

The electron cloud is a model that describes the regions around the nucleus where electrons are likely to be found.

Front

What is the difference between protons and neutrons?

Back

Protons are positively charged particles found in the nucleus, while neutrons are neutral particles that also reside in the nucleus.

Front

How do you determine the charge of an ion?

Back

The charge of an ion is determined by the difference between the number of protons and electrons.
