Front

What must be true for an atom to be electrically neutral?

Back

It must contain the same number of protons and electrons.

Front

Define an orbital in the context of atomic structure.

Back

An orbital is a region in an atom where there is a high probability of finding electrons.

Front

What is the shape of s orbitals?

Back

S orbitals are spherical.

Front

How many electrons can a p orbital hold?

Back

A p orbital can hold a maximum of 6 electrons.

Front

What is the significance of isotopes in chemistry?

Back

Isotopes are variants of a chemical element that have the same number of protons but different numbers of neutrons.

Front

What is the principle behind the Aufbau principle in electron configuration?

Back

Electrons occupy the lowest energy orbitals first before filling higher energy orbitals.
