One lithium (Li) atom can combine with one fluorine (F) atom. Together, they make the formula LiF. Fluorine has seven electrons of it's own. Lithium gives up its one electron to make both atoms happy. So the fluorine atom has eight electrons, and a filled outer shell.

Answer:
Ans: Across a row, the nuclear charge increases while the shielding effect of the inner core remains the same. According to Coulomb's law, increasing nuclear charge creates a greater force, so the valence electrons are held more tightly. The greater the ionization energy, the more difficult it is to remove an electron.
Explanation:
B. A physical combination of two or more different materials.
No, phosphorus is not a metal, In fact, it is a non metal which means that it isn't metal. If you look at the periodic table, the word phosphorus, is in group 15.
Answer:
If some of the stearic-acid hexane solution had evaporated before using it, this would increase Avogadro's number, or the number of atoms per mole. This is because with less hexane in the solution (because only the hexane evaporates), the grams of stearic acid used would be smaller.
