sometimes gaining and sometimes losing valence electrons
|
Detailed explanation-1: -As metals have lesser than 4 electrons in their valence shells, hence for them it is easier to donate electrons to obtain noble gas configuration. Hence metals react by donating electron.
Detailed explanation-2: -A metal atom that loses an electron takes on a positive electric charge; a non-metal that gains an electron becomes negatively charged. Because opposite charges attract, the two atoms stick together, forming a strong, stable chemical bond.
Detailed explanation-3: -Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are called cations. Most metals become cations when they make ionic compounds.
Detailed explanation-4: -Metal Atoms and the Loss of Electrons Atoms of most metals have few valence electrons. Metal atoms tend to lose these valence electrons and form positive ions.
