Why metals can form positive ions? |
|
Answer» Metal elements form positively charged ions called cations because they are located on the left side of the periodic table. Groups 1 and 2 are called the alkali metals and alkaline Earth metals, respectively. These elements all have valence electrons in an s orbital. These electrons are relatively easy for the atom to lose to achieve a stable octet of electrons in its outermost energy shell. Metals have a low ionization enthalpy which allows them to easily lose electrons. When the atoms lose electrons they become cations. Thnx ji |
