Answer:
1.) The number of electrons in an atom's outermost valence shell governs its bonding behaviour. They need to lose only one or two valence electrons to form positive ions and IUPAC is the International Union of Pure and Applied Chemistry. It is an international scientific organization
2.) valence electrons are the outermost energy level in an atom of an element determines many properties of that element including the ways in which the atom can bond with other atoms
3.) group 16 row 2
4.) 6 valence electrons
5.) group 1 row 1
6.) 1 valence electrons
7.) The strongest intermolecular force in water is a special dipole bond called the hydrogen bond. Many molecules can form dipole-bipole bonds without forming hydrogen bonds or even having hydrogen in their molecule
8.) 10 atoms
