Curie and her … WebC a 2 + has smaller ionic radius than K + because it has more nuclear charge. In a given period, on moving from left to right, the nuclear charge increases without addition of shell. The increased nuclear charge attracts the electrons more strongly towards the nucleus. This decreases the ionic size. 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. the pioneer woman chocolate pie
