Unit 6: Ionic Bonds

Front

What is an 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 electron configuration of a magnesium ion (Mg²⁺)?

Back

1s² 2s² 2p⁶ (Magnesium loses two electrons to achieve a stable electron configuration similar to neon.)

Front

What is the chemical formula for the compound formed from calcium and sulfur?

Back

CaS (Calcium sulfide is formed when calcium donates two electrons to sulfur.)

Front

What is the net charge of any ionic compound?

Back

0 (Ionic compounds are electrically neutral overall, meaning the total positive charge equals the total negative charge.)

Front

What is an electron dot structure?

Back

A representation that shows the valence electrons of an atom as dots around the element's symbol.

Front

What is the correct name for Zn₃P₂?

Back

Zinc phosphide (This compound consists of zinc and phosphorus in a 3:2 ratio.)

Front

What is the role of valence electrons in ionic bonding?

Back

Valence electrons are the outermost electrons involved in forming bonds; they are transferred from metals to non-metals in ionic bonds.

Front

How do you determine the formula of an ionic compound?

Back

The formula is determined by balancing the total positive and negative charges of the ions involved.

Front

What is the significance of the octet rule in ionic bonding?

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 stability.

Front

What is a cation?

Back

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