What is the atomic structure?

Back

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

What is an atom?

Back

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

Front

What are protons?

Back

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

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 on the periodic table.

Front

What is the mass number?

Back

The mass number is the total number of protons and neutrons in an atom's nucleus, indicating the atom's mass.

Front

What are isotopes?

Back

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

Front

What is the periodic table?

Back

The periodic table is a tabular arrangement of elements organized by increasing atomic number, showing periodic trends in properties.

Front

What are noble gases?

Back

Noble gases are a group of elements in Group 18 of the periodic table that are chemically inert due to having a full valence shell.
