Unit 7 Review - Bonding

Front

What is the Lewis dot structure for calcium chloride (CaCl2)?

Back

The correct Lewis dot structure shows calcium (Ca) with 2 valence electrons and two chlorine (Cl) atoms, each with 7 valence electrons, forming ionic bonds.

Front

What rule do atoms follow to gain or lose electrons to achieve stability?

Back

The octet rule states that atoms gain, lose, or share electrons to have a full valence shell of 8 electrons.

Front

Which element has a full valence shell?

Back

Neon (Ne) has a full valence shell with 8 electrons.

Front

What is the name of the compound MgS?

Back

The compound MgS is named Magnesium Sulfide.

Front

What charge does a sodium atom acquire when it loses an electron?

Back

When a sodium atom loses an electron, it becomes positively charged.

Front

Define ionic bond.

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions.

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed when two atoms share one or more pairs of electrons.

Front

What is the significance of the octet rule in bonding?

Back

The octet rule helps predict how atoms will bond by indicating that atoms tend to achieve a full outer shell of 8 electrons.

Front

What is the difference between a cation and an anion?

Back

A cation is a positively charged ion, while an anion is a negatively charged ion.

Front

How do you determine the number of valence electrons in an element?

Back

The number of valence electrons can be determined by the group number of the element in the periodic table.
