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 the chemical properties of an element.

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 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 an ion?

Back

An ion is an atom or molecule that has gained or lost one or more electrons, resulting in a net electrical charge.

Front

How do you determine the charge of an ion?

Back

The charge of an ion is determined by the difference between the number of protons and electrons. If protons > electrons, the ion is positively charged; if electrons > protons, it is negatively charged.

Front

What is atomic mass?

Back

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

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 a chemical symbol?

Back

A chemical symbol is a one or two-letter abbreviation used to represent an element on the periodic table.

Front

What is the relationship between protons and electrons in a neutral atom?

Back

In a neutral atom, the number of protons equals the number of electrons, resulting in no overall charge.
