Solubility: Viscosity: Frequency: Ductile: Malleable: Combustible: Radioactive: Corrosive:

Solubility is a property referring to the ability for a given substance, the solute, to dissolve in a solvent. It is measured in terms of the maximum amount of solute dissolved in a solvent at equilibrium. The resulting solution is called a saturated solution.

the state of being thick, sticky, and semifluid in consistency, due to internal friction.or a quantity expressing the magnitude of internal friction, as measured by the force per unit area resisting a flow in which parallel layers unit distance apart have unit speed relative to one another.

1.  frequency

the rate at which something occurs or is repeated over a particular period of time or in a given sample.

Ductile: of a metal) able to be drawn out into a thin wire.

able to be deformed without losing toughness; pliable, not brittle

Malleable:(of a metal or other material) able to be hammered or pressed permanently out of shape without breaking or cracking.

Combustible:able to catch fire and burn easily.

Radioactive:Radioactivity is the spontaneous emission of radiation in the form of particles or high energy photons resulting from a nuclear reaction. ... A substance that contains unstable atomic nuclei is considered to be radioactive. Radioactive decay is a random or stochastic process that occurs at the level of individual atoms.

Corrosive:t ending to cause corrosion(Corrosion is when a refined metal is naturally converted to a more stable form such as its oxide, hydroxide or sulphide state this leads to deterioration of the material.)

Explanation:

(source: google for all)

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
