Use the table below for the next four questions.

ion [a.] symbol cu+1 atomicnumber 29 massnumber [b.] protons [c.] neutrons 34
electrons [d.]

hints:

if an ion has a + charge, that indicates it has more protons (+) than electrons this means the atom has lost electrons.
if an ion has a - charge, that indicates it has more electrons than protons (+). this means the atom has gained electrons.

[a] corresponds with:

a. copper

b. cerium

c. chromium

d. copernicium

[b] corresponds with:

a. 58.933

b. 54.938

c. 63.546

d. none of the above

[c] corresponds with:

[d] corresponds with:

a. 28

b. 29

c. 30

d. none of the above

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
