Solutions are homogeneous mixtures.

Consider neutral atom which has 11 protons and 12 neutrons in the nucleus. The atomic number of the element is [1] 11. The mass number for this atom is [2] 23. The number of electrons is [3] 11. The name of element is [4] sodium which has symbol [5] Na.

Metals are elements which always from cations – positive ions. Metal atoms loose electrons when bond with other atoms.

Particles in solids and liquids are close to each other in a sample causing solids and liquids to have definite volume and being compressible.

Element is the simplest type of matter – it cannot be broken down to any simpler substances.
