How are ions formed from atoms? A. Atoms either lose protons, forming ions with positive charges, or gain protons, forming ions with negative charges. B. Atoms either lose neutrons, forming ions with negative charges, or gain neutrons. forming lons with positive charges. C. Atoms either lose electrons, forming ions with negative charges, or gain electrons, forming lons with positive charges. D. Atoms either lose electrons, forming ions with positive charges, or gain electrons. forming lons with negative charges. 10. 11. If you add an additional neutron to an atom, what do you create? A. a new element B. an isotope C. a reaction D. an ion Which element behaves the MOST like calcium and why? A. K, because it is in the same period and only has one less valence electron. B. Ba, because it is in the same group and has same number of valence electrons. C. Br, because it is in the same period and has more valance electrons. D. Sc, because it is in the same period and has one more valence electron. 12. 13. Which of the following lists of elements is ordered by increasing number of valence electrons? A. LI, C, O, F B. F.O, N, C C. O. S, Se, Te D. Sr, Ca. Mg. Be
