NettetAnd so for this video, we're only talking about the valence electrons for elements in the main groups. When we talk about the main groups, you're using the one through eight system for classifying groups. So one, two, three, four, five, six, seven, and eight. So we're going to ignore the other way to number the groups. NettetThe atomic number of an element is equal to the number of protons and electrons in that element. Therefore, a magnesium atom has twelve protons and twelve electrons. The …

NettetIt has 4 valence electrons, so it can make a 4+ or a 4- charge. But because of its relatively stable half filled orbital, most of the time it takes part in covalent bonding like in organic molecules. On occasion, Carbon can ionize, most commonly 4+.
