Chemistry Paper 1

Front

What is Covalent Bonding?

Back

Covalent bonding happens when two Non-Metals react together. They share the electrons in their outer shells forming bonds.

Front

What type of forces act between the ions in an ionic compound?

Back

Electrostatic forces act between the ions in an ionic compound.

Front

What is an element?

Back

An element is made up of only one type of atom.

Front

How many neutrons does an atom of Boron have?

Back

An atom of Boron has 6 neutrons.

Front

Which scientist discovered atoms have a 'positive nucleus' with electrons around the outside?

Back

Ernest Rutherford discovered that atoms have a 'positive nucleus' with electrons around the outside.

Front

What is an ionic bond?

Back

An ionic bond is formed when a metal and a non-metal react together, resulting in the transfer of electrons and the formation of oppositely charged ions.

Front

What is the atomic number?

Back

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

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 the difference between an atom and a molecule?

Back

An atom is the smallest unit of an element, while a molecule is a group of atoms bonded together.

Front

What is the role of electrons in chemical bonding?

Back

Electrons in the outer shell of atoms are involved in forming chemical bonds by being shared or transferred between atoms.
