What are ionic bonds? A. Bonds that form when any two atoms come in contact .B. Chemical bonds that form from the attraction of negative and positive ions .C. Chemical bonds that form when atoms share electrons equally .D. Chemical bonds that form when atoms share electrons unequally

B

Explanation:

B would be the best answer because an ionic bond occurs usually between a metal and a non-metal. An electron transfer occurs in an ionic bonds because one of the atoms pulls the other atoms electrons so strongly that it basically steals it. Since electrons are negative, the atom that stole the electron become a negatively charged ion, and the one that was stolen from is positive because it has less electrons than protons (+), so they form a positive and negative ion which attract each other.

Opposite charges attract.
