Alithium atom has three electrons. a fluorine has 9 protons and 9 electrons, with 7 electrons in its outer energy level. using a diagram, explain how an atom of lithium an an atom of fluorine combine by ionic bonding

The lithium atom has one electron in its outer shell, so it loses that one electron and becomes a ion. The fluorine atom has 7 electrons in its outer shell so it gains that one electron and becomes a ion. The electrostatic force of attraction between the two ions, because of their charges, bonds them together in an ionic bond to make , Lithium Fluoride.

Couldn't add a diagram, but hope it helps.

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

i think it is true since you can test the answer and can use observations to complete it.
