Lesson 20 :)

Today! We learned more about charges in a compound. Vocab word! Ionic compound is composed of positive and native ions, formed when metal and nonmetal atoms combine. A rule that really helps when distinguishing the charge is metal (+) nonmetal (-) -IDE. Metal and nonmetal elements combine to form ionic compounds as I earlier talked about, and the electron arrangements of cations and anions resemble noble gas atoms (which you should already know!) another rule for the zero charge is in an ionic compound, the positive charges on the metal cations and the negative charges on the nonmetal anions sum to 0! Lastly! Something important to know, is that the number of electrons of the atoms in an ionic compound usually totals to 8 or a multiple of 8! Below is my homework to better explain all of the information above! :)
