According to Dalton, if 2 grams of element X combine with 4 grams of element Y to form compound XY, how many grams of element X
adell [148]
The ratio of reactant in grams would be influenced by the reaction equation and the molar mass of the elements. But the ratio of a reactant needed in grams would be same for a reaction.
If 2 grams of element X combine with 4 grams of element Y to form compound XY, it means the ratio of reactant in grams<span> would be 2:4 or 1:2

The number of element X needed for 28grams of element Y would be:
1/2 * 28grams = 14 grams.</span>

What is the quantum number set of the ground-state electron that is found in lithium (Li) but not in helium (He)?
statuscvo [17]
The electron configuration of lithium atom is: Li:[He]2s^1

The number "2" is the value of the principal quantum number "n". Letter "s" is associated with the value of secondary quantum number "l" and it is equal to zero. The value of "m" (or magnetic quantum number) is zero too. The quantum number set for the highest energy electron will be (2, 0, 0, 1/2).
