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

How do you calculate the atomic mass of an element?

Back

The atomic mass is calculated by adding the number of protons and neutrons in the nucleus of an atom.

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.

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 significance of the atomic number?

Back

The atomic number is the number of protons in an atom's nucleus and determines the element's identity and position in the periodic table.
