Front

What type of bond is formed when electrons are shared between atoms?

Back

Covalent bond

Front

What type of bond is formed when electrons are transferred from one atom to another?

Back

Ionic bond

Front

What is the general formula for calculating the number of valence electrons in an atom?

Back

The number of valence electrons is equal to the group number of the element in the periodic table.

Front

What is the primary characteristic of ionic compounds?

Back

They are formed from the electrostatic attraction between oppositely charged ions.

Front

What is the primary characteristic of covalent compounds?

Back

They typically have lower melting and boiling points compared to ionic compounds.

Front

What is the significance of the octet rule in chemical bonding?

Back

Atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What is an example of a covalent compound?
