Some 1 help me plz!!! Which statement comparing ionic and covalent bonds is correct?

a. Elements in Group 1A are more likely to form covalent bonds than ionic bonds with other atoms.
b. Covalent bonds tend to be less polar than ionic bonds.
c. More electrons are transferred from covalent bonds than ionic bonds.
d. The difference between electronegativities is greater in covalent bonds than for atoms in ionic bonds.

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.

particle   p is an electron and particle q is a neutron

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
