True or False: Matter exists only in two states: solid and liquid.

False. Matter exists in three primary states: solid, liquid, and gas.

What are the characteristics of particles in the solid state of matter?

In the solid state, particles are closely packed in a fixed, orderly arrangement, have a definite shape and volume, and exhibit limited movement due to strong intermolecular forces.

Gases have a definite shape and volume. True or False?

False. Gases have neither a definite shape nor volume; they expand to fill their container.

What occurs in Bose-Einstein Condensate (BEC) at temperatures close to absolute zero?

Particles occupy the same space and quantum state, acting as a single quantum entity.

Fill in the blank: The temperature at which a solid turns into a liquid is known as the ___.

Melting point

True or False: Combustion is the process of burning in the absence of oxygen.

False. Combustion occurs in the presence of oxygen.

The modern atomic theory states that atoms are the smallest units of matter that ___ and ___ when chemical reactions occur.

Cannot be created or destroyed, can combine in fixed ratios

True or False: J.J. Thomson proposed the nuclear model of the atom.

False; J.J. Thomson proposed the 'plum pudding' model, while Ernest Rutherford proposed the nuclear model.

What distinguishes a homogeneous mixture from a heterogeneous mixture?

A homogeneous mixture has a uniform composition throughout, while a heterogeneous mixture retains distinct individual properties.

Atoms consist of a nucleus containing ___ and ___, surrounded by ___ in various energy levels.

Protons and neutrons; electrons

True or False: Ionic bonds are formed by the sharing of electrons between atoms.

False; Ionic bonds are formed by the transfer of electrons from one atom to another.

True or False: The atomic radius increases across a period from left to right.

False - The atomic radius decreases across a period due to increasing nuclear charge.

The metallic character of elements ___ across a period and ___ down a group.

Decreases; increases
