WebThe requirements for the formation of an ionic bond are an atom that will lose one or more electrons and an atom that will gain one or more electrons. Neither of these processes can require a large amount of energy. For this reason, ions with charges of + 1, −1, +2, and −2 are much more common than those with charges of + 3 or -3 or more. WebRadium is a chemical element with atomic number 88 which means there are 88 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the … WebOxygen's charge is going to be -2 since that's elements in its group display, and the overall charge of the compound is 0 (neutral). So to figure how iron's charge it would be: (1)x + (1)-2 = 0, or x = 2, the 1's in parentheses being the number of iron and oxygen atoms. So iron has a +2 charge. dying counter
