it is neutral
and may not exist independently
atom X+1
it is ion which has a charge on it positive or negative

Calcium has the greatest mass of the first twenty elements with a mass of approximately 40.08
Convert mole to gram by multiplying the molar mass of sodium
0.500mol Na x 22.990g = 11.495g of Na
High temperature and pressure produce the highest rate of reaction. However, this must be balanced with the high cost of the energy needed to maintain these conditions. Catalysts increase the rate of reaction without affecting the yield. This can help create processes which work well even at lower temperatures.
I hope this helps you.
