Atomic Structure

Front

Subatomic particles with a negative charge

Back

Electrons are subatomic particles that carry a negative charge and are found in the electron cloud surrounding the nucleus of an atom.

Front

What is the atomic mass of Boron?

Back

The atomic mass of Boron is 11.

Front

A tiny but very dense, positively charged portion of the atom that holds most of the atomic mass

Back

The nucleus is the central part of an atom, containing protons and neutrons, and holds most of the atom's mass.

Front

Where are electrons likely to be found as they travel around the nucleus?

Back

Electrons are likely to be found in the electron cloud, which is the region around the nucleus where electrons are most likely to be located.

Front

How many neutrons does Fluorine have?

Back

Fluorine has 10 neutrons.

Front

What are protons?

Back

Protons are positively charged subatomic particles found in the nucleus of an atom.

Front

What is the charge of neutrons?

Back

Neutrons have no charge; they are neutral particles found in the nucleus of an atom.

Front

What is an atom?

Back

An atom is the smallest unit of matter that retains the properties of an element, consisting of a nucleus surrounded by electrons.

Front

What is the role of the electron cloud?

Back

The electron cloud is the area around the nucleus where electrons are likely to be found, influencing the atom's chemical properties.

Front

What is the difference between atomic number and atomic mass?

Back

The atomic number is the number of protons in an atom, while the atomic mass is the total number of protons and neutrons.
