What is an ionic bond?

Back

An ionic bond forms when valence electrons are transferred from one atom to another, resulting in charged ions that are attracted to each other.

Where are protons and neutrons found in an atom?

Back

Protons and neutrons are found in the nucleus of an atom.

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

How many electrons does a Boron atom contain?

Back

A Boron atom contains 5 electrons.

Front

How many protons does a Boron atom have?

Back

A Boron atom has 5 protons.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds.

Front

What is the difference between an atom and an ion?

Back

An atom is neutral, while an ion is charged due to the loss or gain of electrons.

Front

What is the role of electrons in chemical bonding?

Back

Electrons are involved in forming bonds between atoms, either by being shared (covalent bonds) or transferred (ionic bonds).

Front

Define the term 'nucleus' in the context of an atom.

Back

The nucleus is the central part of an atom, containing protons and neutrons.

Front

What is the significance of the atomic mass?

Back

The atomic mass is the weighted average mass of an element's isotopes, reflecting the number of protons and neutrons.
