valence electron does not determine an atom but it only determine the eagerness of the element either to receive or to gain more electrons,for the one of an atom e.g oxygen gas can be turned into an...
They determine many things. They can be used to predice hybridization, determine octet, be used to assign formal charges. The simplest answer would be for a intro to chem class, they determine the...
Yes, this is essentially correct. The valence electrons set the tone for the chemical behavior of any atom. Those valence electrons call the shots as atoms tend to want to have a full valence shell....
