Chemical Bonding

Front

What is a compound?

Back

A compound is a substance formed when two or more different elements are chemically bonded together. For example, salt (NaCl) is a compound made of sodium and chlorine.

What is an element?

Back

An element is a pure substance that cannot be broken down into simpler substances by chemical means. Each element is made up of atoms that have the same number of protons.

Front

What type of bond involves the transfer of electrons from one atom to another?

Back

Ionic bond.

Front

What type of bond involves the sharing of valence electrons between atoms?

Back

Covalent bond.

Front

What is the octet rule?

Back

The octet rule states that atoms are most stable when they have eight electrons in their outer shell.

Front

What is a valence electron?

Back

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

Front

What is a metallic bond?

Back

A metallic bond is a type of chemical bond that occurs between metal atoms, where electrons are shared in a 'sea of electrons' allowing for conductivity and malleability.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons between atoms.

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together, which can be of the same or different elements.

Front

What is a chemical formula?

Back

A chemical formula is a way of expressing information about the proportions of atoms that constitute a particular chemical compound.
