Help with explanation if possible.
Nae Section -Date Now let's look at chlorine A chlorine atom has how many protons Therefore, we know that a chlorine atom has how many electrons? How many electrons will go in the first shell? How many in the second shell? Nucleus How many in the third? Draw this in Figure 2.2 We know that a chlorine atom requires eight electrons in its valence shell to become stable. Will it be easier for chlorine to...
