Explanation / Answer
What does the symbol Mg2+ represent? A magnesium atom that has lost 2 electrons (electrons arenegative, and an atom cannot acquire protons) Select the correct description of valence electrons. Electrons that occupy the outer energy level (definition ofvalence electrons) Atoms A and B have achieved the noble gas structure by sharingelectrons. Select the correct statement about A and B. A and B have formed a covalent bond (only covalent bondsinvolve the actual sharing of electrons) What type of reaction has the general form XY + Z XZ +Y. Replacement (In this reaction, Z is replacing Y in thecompound with X) Natural radiation from radioactive elements consistsof Alpha, beta, or gamma rays (definition of alpha, beta, andgamma rays).
