BF4−BF4− Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons. To change the symbol of an atom, double-click on the atom and enter the letter of the new atom. Show the charge of the ion over the central atom.

Total electron pairs is equal to 4

Total no. of bond pairs = 4

Total no. of lone pairs of central atom = 0

Charge on central atom = (-1)

Explanation:

 Calculation of total electron pairs Then calculate total no. of bond pairs then find the structureFinally show charge on central atom usinfg formal charge calculation

If the water vapor content stays the same and the temperature drops, then the relative humidity increases. its vise versa.if the water vapor content stats the same and the temperature rises, the relative humidity decreases. so, yes, i'd say that temperature and humidity have a strong relationship.
