Write the electron configuration for the neutral atom or ion
indicated in the space provided. It is OK to use the condensed
notation in which the noble-gas core is represented using the
appropriate symbol in square brackets. For example, the electron
configuration of Al is [Ne]3s23p1
(a) Write the electron configuration of Sn
(Z = 50).
(b) Write the electron configuration of Ni2+
(Z = 28).
(c) Write the electron configuration of Te2–
(Z = 52).
(d) Write the electron...

unpaired electrons are there in the ground state of this atom?
A neutral atom has the following electronic configuration:
1s2 2s2 2p6 3s23p5How many protons are in the atomic nucleus and to which group of
the periodic table does this element belong?
The electron configuration of a neutral atom in the ground state
is 1s^2 2s^2 2p^6 3s^2.
a) Write a complete set of quantum numbers for each of the
electrons and name the element.
