What charge does an ion have if it has more protons than electrons? A. A net negative charge
B. Neutral, since protons are inside the nucleus
C. No charge
D. A net positive charge

D. A net positive charge

Explanation:

Because the electrons have negative charge and protons have positive charge, so if the ion have more protons it means it have more positive charge

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
