SPS2. Atomic Bonding and Compounds

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically between a metal and a non-metal.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons, usually between non-metal atoms.

Front

How do ionic compounds typically form?

Back

Ionic compounds form when electrons are transferred from one atom to another, resulting in the formation of positive and negative ions.

Front

What is the general formula for ionic compounds?

Back

Front

What is the significance of the octet rule in bonding?

Back

The octet rule states that atoms tend to bond in such a way that they each have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What are the properties of ionic compounds?

Back

Ionic compounds typically have high melting and boiling points, are solid at room temperature, and conduct electricity when dissolved in water.

Front

What are the properties of covalent compounds?

Back

Covalent compounds usually have lower melting and boiling points compared to ionic compounds, can be gases, liquids, or solids, and do not conduct electricity.

Front

What happens to an atom when it loses electrons?

Back

When an atom loses electrons, it becomes a positive ion (cation).

Front

What happens to an atom when it gains electrons?

Back

When an atom gains electrons, it becomes a negative ion (anion).

Front

Why do ionic compounds have high melting and boiling points?

Back

Ionic compounds have high melting and boiling points because they are held together by many strong ionic bonds.
