Question

1. choose the best answers using a periodic table. (see companion material attached.) which of the following is ionically bonded? albr₃ cu₃zn₂ so₃ ccl₄ 13) choose the best answers. magnesium will __ 2 electrons to form a ion called a(n) __. gain, negative, anion lose, positive, cation share, negative, cation 14) choose the best answers.

Explanation:

• Question 12: Ionic bonds form between metals and non - metals. \(AlBr_3\) has a metal (\(Al\)) and non - metals (\(Br\)). \(Cu_3Zn_2\) is an alloy (metallic bonding). \(SO_3\) and \(CCl_4\) are covalent compounds (non - metals only).
• Question 13: Magnesium (\(Mg\)) is a metal. Metals tend to lose electrons. When \(Mg\) loses 2 electrons, it forms a positively charged ion (\(Mg^{2 + }\)). Positively charged ions are called cations.

Answer:

1. \(AlBr_3\)
2. lose; positive; cation
