Front

What is a characteristic of metallic compounds?

Back

Metallic compounds are typically conductive and malleable, but they are not soluble in water.

Front

What happens to electronegativity as you move left on the periodic table?

Back

Electronegativity increases as you move to the right and decreases as you move down the periodic table.

Front

What is the correct formula for barium chlorate?

Back

Ba(ClO₃)₂

Front

What type of bond is formed when valence electrons are transferred?

Back

Ionic bond.

Front

Which element has the electron configuration [Ne] 3s² 3p⁵?

Back

Chlorine.

Front

Define electronegativity.

Back

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

Front

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

Back

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

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What is the significance of valence electrons?

Back

Valence electrons determine an atom's chemical properties and its ability to bond with other atoms.

Front

What is a common property of ionic compounds?

Back

Ionic compounds typically have high melting and boiling points and are soluble in water.
