Question

Comment: “metals are electropositive elements”.

Answer 1

1. Electropositive element: An electropositive element is one that tends to lose electrons and form positively charged ions.
2. Metals: The elements which can easily form positive ions (cation) by losing or donating electrons are called metals.
3. For example, Sodium$\left(\mathrm{Na}\right)$, with atomic number$11$, has $1{\mathrm{e}}^{-}$ in its valence shell which can easily lose to form ${\mathrm{Na}}^{+}$ ion.
4. Metals typically possess a few electrons in their valence shell which they can lose to form a positive ion, hence metals are called electropositive elements.
5. Examples: Sodium$\left(\mathrm{Na}\right)$, Aluminium$\left(\mathrm{Al}\right)$, Copper$\left(\mathrm{Cu}\right)$, Iron$\left(\mathrm{Fe}\right)$, Tin$\left(\mathrm{Sn}\right)$, Gold$\left(\mathrm{Au}\right)$, Lead$\left(\mathrm{Pb}\right)$, etc.
