Final Assessment S.1

Front

Which atom has a larger atomic radius?

Back

Sb (Antimony) has a larger atomic radius compared to Cl (Chlorine), Br (Bromine), and O (Oxygen) due to its position in the periodic table.

Front

What charge does a cation have and why?

Back

A cation has a positive charge because it has lost electrons.

Front

What are nonpolar bonds?

Back

Nonpolar bonds are bonds that share a pair of electrons equally between two atoms.

Front

What is matter?

Back

Matter is anything that has mass and occupies space.

Front

What are ions?

Back

Ions are atoms or groups of atoms that have a positive or negative charge.

Front

What is the trend of atomic radius in the periodic table?

Back

Atomic radius increases down a group and decreases across a period from left to right.

Front

What is the difference between cations and anions?

Back

Cations are positively charged ions formed by losing electrons, while anions are negatively charged ions formed by gaining electrons.

Front

What is electronegativity?

Back

Electronegativity is the ability of an atom to attract electrons in a chemical bond.

Front

What is 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.

Front

What is a polar bond?

Back

A polar bond is a covalent bond between two atoms where the electrons are shared unequally, resulting in a partial positive and negative charge.
