Ionic Compounds & Periodic Trends

Front

What is an alkali metal?

Back

An alkali metal is any of the elements in Group 1 of the periodic table, which are highly reactive and include lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).

What does the oxidation number indicate?

Back

The oxidation number indicates the number of electrons an atom has gained, lost, or shared when forming a chemical bond. It helps in determining the charge of an ion.

Front

What is the charge of an ionic compound?

Back

An ionic compound is neutral (no charge) overall, as it is formed from the combination of positively charged cations and negatively charged anions.

Front

How many electrons does a phosphorus atom need to gain to achieve a full octet?

Back

A phosphorus atom needs to gain 3 electrons to achieve a full octet.

Front

What period is Bromine located in on the periodic table?

Back

Bromine is located in period 4 of the periodic table.

Front

Define ionic bond.

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically between a metal and a non-metal.

Front

What is the significance of the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons, leading to greater stability.

Front

What are the properties of ionic compounds?

Back

Ionic compounds typically have high melting and boiling points, are soluble in water, and conduct electricity when dissolved or molten.

Front

What is a cation?

Back

A cation is a positively charged ion that is formed when an atom loses one or more electrons.

Front

What is an anion?

Back

An anion is a negatively charged ion that is formed when an atom gains one or more electrons.
