Front

Define a covalent bond.

Back

A chemical bond formed by the sharing of electron pairs between atoms.

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.

Front

What is the mole concept in chemistry?

Back

The mole is a unit that measures the amount of substance, defined as containing 6.022 x 10²³ entities (atoms, molecules, etc.).

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

What is the significance of the octet rule?

Back

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