Question
Chapter 2, Problem 48P
Interpretation Introduction
Interpretation:
The condensed ground-state electron configuration of He (2) should be written.
Concept Introduction:
The protons and neutrons of an atom are present in the nucleus of an atom whereas the electrons are always moving around the nucleus of an atom that is they possess kinetic energy. The lowest possible energy level of an electron in an atom is its ground state.
The electrons are arranged around the nucleus of an atom in an increasing order of energy levels and this description of orbitals of atom occupied by electrons is known as electronic configuration.

Students have asked these similar questions
3- (a) Write out the full electron configuration of Calcium (Ca). (b) How many electrons are in the n=3
shell of Calcium?
1a. Which ions have the same number of electrons as an atom of argon?
(a) S2- (b) P3- (c) Be2+ (d) Ca2+
1b. Which ions have the same number of electrons as an atom of krypton?
(a) Se2- (b) As3- (c) Ca2+ (d) K+
vi. Answer true or false.
(a) Elements in the same column of the Periodic Table have the
same outer-shell electron configuration.
(b) All Group 1A elements have one electron in their valence
shell.
(c) All Group 6A elements have six electrons in their valence
shell.
(d) All Group 8A elements have eight electrons in their valence
shell.
(e) Period 1 of the Periodic Table has one element, period 2 has
two elements, period 3 has three elements, and so forth.
(1) Period 2 results from filling the 2s and 2p orbitals and,
therefore, there are eight elements in period 2.
(g) Period 3 results from filling the 3s, 3p, and 3d orbitals and,
therefore, there are nine elements in period 3.
(h) The main-group elements are s block and p block elements.
