As a chlorine atom becomes a negative ion, the atom

gains an electron and its radius increases

gains an electron and its radius decreases

loses an electron and its radius increases

loses an electron and its radius decreases

The bonds in BaO are best described as

ionic, because valence electrons are transferred

covalent, because valence electrons are shared

covalent, because valence electrons are transferred

ionic, because valence electrons are shared

Which property best accounts for the conductivity of metals?

the free electrons in the valence energy levels

the relatively high first ionization energy

the malleability of most metals

the filled inner electron energy levels

Why is a molecule of CO₂ nonpolar even though the bonds between the carbon atom and the oxygen atoms are polar?

The shape of the CO₂ molecule is symmetrical.

The shape of the CO₂ molecule is asymmetrical.

The CO₂ molecule has a deficiency of electrons.

The CO₂ molecule has an excess of electrons.

In aqueous solution, a chloride ion is attracted to which end of the water molecule?

the hydrogen end, which is the positive pole

the hydrogen end, which is the negative pole

the oxygen end, which is the positive pole

the oxygen end, which is the negative pole

Two fluorine atoms are held together by a covalent bond. Which statement correctly describes this bond?

It is nonpolar and forms a nonpolar molecule.

It is polar and forms a polar molecule.

It is polar and forms a nonpolar molecule.

It is nonpolar and forms a polar molecule.

c) Explain why the particles of this substance are nonconductors of electricity.

The particles have no free electrons or ions to carry charge.

The particles are too large to move and conduct electricity.

The particles are made of insulating material.

The particles are in a gaseous state, preventing conduction.

Base your answer to the following question on the information below. Explain why Lewis electron-dot diagrams are generally more suitable than electron-shell diagrams for illustrating chemical bonding.

Lewis diagrams focus on valence electrons which are involved in bonding.

Electron-shell diagrams show all electrons, making it complex.

Lewis diagrams are simpler and highlight bonding interactions.

Electron-shell diagrams are more detailed but less focused on bonding.

The formula unit for a certain ionic compound contains parentheses. What must be true?

The formula unit contains more than one of the same polyatomic ion.

The formula unit contains no polyatomic ions.

The formula unit contains two different polyatomic ions.

The formula unit contains either a polyatomic cation or a polyatomic anion, but not both.

Metals all typically form what charge?

Varies within S, P, D, and F blocks

Positive in S & P block varies in the D block

Halogens all typically form what charge?

Negative one, written as a -1 superscript

Positive one Written as a 1+ superscript

Negative one, written as a 1- subscript

Positive 1 written as a 1+ subscript
