Units 5 and 6 Review

Front

What is a transition metal?

Back

Transition metals are elements found in groups 3-12 of the periodic table, characterized by their ability to form variable oxidation states and colored compounds. Example: Iron (Fe) is a transition metal.

Front

Which element is a halogen?

Back

Halogens are elements found in group 17 of the periodic table, known for their reactivity and tendency to form salts with metals. Example: Fluorine (F) is a halogen.

Front

What happens to atomic radius as you move down a group in the periodic table?

Back

The atomic radius increases as you move down a group due to the addition of electron shells.

Front

What does it mean for a substance to be polar?

Back

A polar substance has an uneven distribution of charge, resulting in partial positive and negative charges.

Front

What is the molecular geometry of CCl4?

Back

CCl4 has a tetrahedral molecular geometry due to the four bonding pairs of electrons around the central carbon atom.

Front

Define atomic number.

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

What is the significance of the periodic table?

Back

The periodic table organizes elements based on their atomic number, electron configuration, and recurring chemical properties.

Front

What are noble gases?

Back

Noble gases are elements in group 18 of the periodic table, known for their lack of reactivity due to having a full valence shell. Example: Neon (Ne).

Front

What is an ion?

Back

An ion is an atom or molecule that has gained or lost one or more electrons, resulting in a net charge.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.
