Front

What is the nucleus of an atom?

Back

The nucleus is the central part of an atom, containing protons and neutrons, and it holds most of the atom's mass.

Front

What is a Bohr Model?

Back

A Bohr Model is a simplified representation of an atom that shows electrons in circular orbits around the nucleus.

Front

How many protons does Lithium have?

Back

Lithium has 3 protons.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

How many valence electrons does Phosphorus have?

Back

Phosphorus has 5 valence electrons.

Front

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

What is the electron cloud?

Back

The electron cloud is the region around the nucleus of an atom where electrons are likely to be found.

Front

How many electrons can the first shell of an atom hold?

Back

The first shell can hold a maximum of 2 electrons.

Front

What is the significance of the periodic table?

Back

The periodic table organizes elements based on their atomic number and properties, helping to predict their behavior.

Front

What is an isotope?

Back

An isotope is a variant of an element that has the same number of protons but a different number of neutrons.
