Question

1. physical properties: a. what type of elements are good conductors of heat & electricity b. what type of elements are poor conductors of heat & electricity c. magnetism: what elements are magnetic? (i can see nick) d. solubility: solubility increases as temperature ____________ e. boiling point & melting point: what state of matter is this property best used to identify? 8. what is the smallest unit of an element? 9. what three subatomic particles make up an atom? 10. which 2 subatomic particles are found in the nucleus of an atom? 11. where can you find the electrons in an atom?

Explanation:

a. Metals are good conductors due to their free - moving electrons.
b. Non - metals are poor conductors as they lack freely moving charge carriers.
c. Iron, nickel, and cobalt are common magnetic elements.
d. For most solids dissolved in liquids, solubility increases as temperature increases.
e. Boiling and melting points are used to identify substances in the solid and liquid states.
