Pls help due in an hour Valence Electrons: how they increase across the Periodic table (periodic trend), and how they relate to both ionic and covalent bonding?

Valence electrons are outer shell electrons with an atom and can participate in the formation of chemical bonds. In single covalent bonds, typically both atoms in the bond contribute one valence electron in order to form a shared pair. The ground state of an atom is the lowest energy state of the atom

momentum of soft ball three times less than baskey ball

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
