Which of the following elements would most likely have the physical property of malleability?
a. n
b. he
c. cu
d. p

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
