A xenon atom has a diameter of approximately 216 pm. If xenon atoms were placed into a straight line, how many would it take to span a distance of 1 inch?
How many moles of xenon atoms would that be? (1 pm = 1 x 10-12 m; 1 in =
0.0254 m)

A) 1.18 x 108 atoms/in
1.95 x 10-16 mol

B) 2.36 x 108 atoms/in
9.75 x 10-17 mol

C) 1.18 < 1010 atoms/in
1.95 x 10-14 mol

D) 2.36 1010 atoms/in
9.75 × 10-15 mol

I think A A) 1.18 x 108 atoms/in

1.95 x 10-16 mol

Explanation:

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
