Front

What is Electronegativity?

Back

Electronegativity is the tendency for an atom of an element to attract the electrons of another element when they are chemically combined.

Front

How many neutrons does a Carbon-13 atom have?

Back

A Carbon-13 atom has 7 neutrons.

Front

What state of matter has no fixed volume or shape and fills its entire container uniformly?

Back

Gas.

Front

What is the formula for the ionic compound formed between magnesium and iodine?

Back

MgI₂.

Front

What is Ionization Energy?

Back

Ionization Energy is the energy needed to remove an electron from an atom.

Front

Define Atomic Radius.

Back

Atomic Radius is the distance from the nucleus of an atom to the outermost shell of electrons.

Front

What is the difference between a solid and a liquid?

Back

A solid has a fixed shape and volume, while a liquid has a fixed volume but takes the shape of its container.

Front

What is the Shielding Effect?

Back

The Shielding Effect is the phenomenon where inner electrons shield outer electrons from the full effect of the nucleus's positive charge.

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?

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.
