How to draw a covalent bonding plz help ppl

Explanation:

A single covalent bond is made up of 2 electrons (one from each atom). It is represented with a single line.

Each line is represented as one dot and one cross (. x)

A double covalent bond is made up of 4 electrons (2 from each atom). It is represented using 2 lines. As dot and cross, it will be represented with 2 dots and 2 crosses.

A triple covalent bond is made up of 6 electrons (3 from each atom). It is represented using 3 lines. As dot and cross, it will be represented with 3 dots and 3 crosses.

Know the number of electron (s) needed by the atom to have noble gas configuration / stable (Key: You should know your electron arrangement / group number / Refer to table provided)*.

Groups and the number of electrons needed for atoms to have noble gas configuration or have full outer shell(s).

Group 4: Four (4) electrons needed for the outer shell to become full / noble gas configuration;

Group 5: Three (3) electrons needed by the atom to have a full outer shell / noble gas configuration;

Group 6: Two (2) electrons needed

Group 7: One (1) electron needed

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

hope this you

elements make up everything, and they combine to make compounds.
