b. 98 electronsThe maximum number of electrons in a shell is 2n², where n is the principle quantum number. Hence, an element of period 7 (n = 7) can hold up to a maximum of 98 electrons.
Molecularity in chemistry is the number of molecules that come together to react in an elementary reaction and is equal to the sum of stoichiometric coefficients of reactants in this elementary reaction. Depending on how many molecules come together, a reaction can be unimolecular, bimolecular or trimolecular.
cooking oil is a colloid and when we combine the two it will also form colloi? heterogeneous which means it is not uniform
