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 subatomic particles found in the nucleus of an atom. The number of protons determines the atomic number and identity of an element.

Front

What are neutrons?

Back

Neutrons are neutral subatomic particles found in the nucleus of an atom. They contribute to the atomic mass but do not affect the charge of the atom.

Front

What are electrons?

Back

Electrons are negatively charged subatomic particles that orbit the nucleus of an atom. They are involved in chemical bonding and reactions.

Front

What is the atomic number?

Back

The atomic number is the number of protons in the nucleus of an atom, which defines the element and its position in the periodic table.

Front

What is atomic mass?

Back

Atomic mass is the weighted average mass of an atom's isotopes, measured in atomic mass units (amu). It reflects the total number of protons and neutrons.

Front

What is an isotope?

Back

Isotopes are variants of the same element that have the same number of protons but different numbers of neutrons, resulting in different atomic masses.

Front

What is the charge of a proton?

Back

The charge of a proton is +1.

Front

What is the charge of a neutron?

Back

The charge of a neutron is 0 (neutral).

Front

What is the charge of an electron?

Back

The charge of an electron is -1.
