The English scientist John Dalton were one of the early scientists who paved the way to science, particularly in atomic chemistry. His atomic theory jumpstarted further developments made by J.J Thomson, Rutherford, Bohr, Schrodinger and many more.
Dalton's atomic theory can be summarized in 5 key points:
1. Atoms are tiny, indivisible and indestructible particles of an element.
2. Atoms of different elements vary in size and mass.
3. Atoms of an element are uniform in size and mass.
4. Compounds are formulated by a fixed ratio of individual atoms of elements.
5. Reactions undergo by rearranging the atoms of the reactants to form the products.
From the choices, the acceptable answer would be: <span>The ratio of atoms in a compound is fixed. </span>
Answer: Colloid
Explanation:
A suspension comprises of a substance that is dispersed in a liquid. Colloid may result when oil is mixed with water. In colloid , the other substance is merely scattered in a another and form a lower layer when the colloid is left to stand. A dispersion oil in water is called an emulsion. It is a type of colloid.
Answer:
A base forms hydroxide ions in water.

Answer: Solubility.
Explanation:
Solubility is defined as the maximum amount of solute dissolved per 100 g of the solvent at a certain fixed temperature to form a saturated solution.
STP condition is Standard Temperature and Pressure condition which is temperature of 273 K and pressure of 1 atm.
Thus the scientific term for "the number of grams of solute dissolved in 100 g of the solvent to form a saturated solution at STP" is called as Solubility.
