Atomic Structure Flashcard

Front

What is the atomic structure of an atom?

Back

An atom consists of a nucleus containing protons and neutrons, surrounded by electrons in orbitals.

Front

What is the charge of a proton?

Back

A proton has a positive charge.

What is the charge of an electron?

Back

An electron has a negative charge.

Front

How do you change an element into a different element?

Back

By adding or removing protons from the nucleus.

Front

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom.

Front

What is the mass number of an atom?

Back

The mass number is the total number of protons and neutrons in the nucleus.

Front

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

Back

Number of neutrons = Mass number - Atomic number.
