Which of the following bonds rely on the attraction of positive and negative charges?

a hydrogen bonds
b ionic bonds and hydrogen bonds
c ionic bonds
d covalent bonds
e ionic bonds and covalent bonds

The bonds that rely on the attraction of positive and negative charges are ionic and Hydrogen bonds. Option B

Explanation: chemical bonds are attraction which exists between atoms and molecules that leads to the formation of chemical compounds. Examples of chemical bonds includes:

- Ionic bonding: this is a type of chemical bonding that involves attraction between a positively charged ion and a negatively charged ion, this occurs in order to obtain a full valence shell for both atoms.

- Hydrogen bond: there is donor and acceptor atoms which constitute the bond. It is primarily electrostatic force of attraction between a hydrogen (H) atom which is covalently bound to a more electronegative atom or group,the hydrogen bond donor (Dn) and another electronegative atom bearing a lone pair of electrons—the hydrogen bond acceptor (Ac).

- covalent bond: this type of chemical bonding requires sharing of electrons. It doesn't involve attraction of positive and negative charges.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

the answer is 75.0%.
