Atomic structure

What is the atomic structure?

Back

The atomic structure refers to the arrangement of protons, neutrons, and electrons in an atom, which determines its properties and behavior.

Front

What are protons?

Back

Protons are positively charged particles found in the nucleus of an atom. They determine the atomic number and identity of an element.

Front

What are neutrons?

Back

Neutrons are neutral particles found in the nucleus of an atom. They contribute to the atomic mass and stability of the nucleus.

Front

What are electrons?

Back

Electrons are negatively charged particles that orbit the nucleus of an atom in electron shells. They are involved in chemical bonding.

Front

How do you calculate the number of neutrons in an atom?

Back

The number of neutrons can be calculated by subtracting the atomic number (number of protons) from the atomic mass.

Front

What is atomic mass?

Back

Atomic mass is the weighted average mass of an element's isotopes, measured in atomic mass units (amu).

Front

What is the nucleus of an atom?

Back

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

Front

What is the charge of a proton?

Back

A proton has a positive charge.

Front

What is the charge of a neutron?

Back

A neutron has no charge (it is neutral).

Front

What is the charge of an electron?

Back

An electron has a negative charge.
