In which of the following substances does sharing of electrons between two atoms occur?
He
Nal
PO43–
Ag
Sharing of electrons between two atoms occurs in the substances: He, Nal, and PO43–.
To determine which of the given substances involve the sharing of electrons between two atoms, we need to understand the concept of chemical bonding.
Chemical bonding refers to the attractive forces that hold atoms together in a compound. There are three types of chemical bonds: covalent, ionic, and metallic.
A covalent bond occurs when two atoms share electrons. This type of bonding is typically found between nonmetals. On the other hand, an ionic bond occurs when there is a transfer of electrons from one atom to another, resulting in the formation of positive and negative ions. Metallic bonding occurs between metal atoms and involves a delocalization of electrons.
Among the given substances, p and explainstrophe;He is an element, Nal is an ionic compound, and Ag is a pure metal. To determine if sharing of electrons occurs, we need to examine the last option, PO43–.
PO43– represents a polyatomic ion, specifically phosphate. The phosphate ion consists of four oxygen atoms covalently bonded to a central phosphorus atom. Within the phosphate ion, each oxygen atom shares electrons with the central phosphorus atom, resulting in a sharing of electrons between multiple atoms.
Therefore, the substance where sharing of electrons between two atoms occurs is PO43–.
well, He and Ag are atoms, so no sharing there.
So, now you have to choose between the other two. Are they ionic or covalent?
