Question

All nonmetals except( hydrogen) form negatively charged ions ___in their valence shell(Donate /Accept)

Answer 1

Non-metals are the elements that gain electrons because they contain more valence electrons than metals, hence they prefer to gain electrons rather than lose them while forming a stable octet.

• Non-metals are elements that accept or gain electrons to generate negative ions.
• The outermost shell of non-metals normally has 4, 5, 6, or 7 electrons.
• Non-metals are materials that lack all of the characteristics of metals.
• They are usually gases, although they can also be liquids.
• Carbon, sulfur, and phosphorus, for example, are solid at normal temperatures and are exceptions.

Accepting electrons:

The outermost shell of non-metals normally has 4, 5, 6, or 7 electrons.

• The nonmetal takes the electrons and forms a negatively charged anion as a result.
• For example, Chlorine (Cl) has seven electrons in its outer shell in its lowest energy state (called the ground state). To obtain one electron is more energy-efficient than losing seven.
• Chlorine gains an electron, resulting in a total of 17 protons and 18 electrons.
• Chlorine has a charge of one because it has one more electron than protons, making it a negative ion.

Hence All nonmetals except( hydrogen) form negatively charged ions by accepting electrons in their valence shell.
