The electron configuration of Americium ( Am ) has to be depicted using noble gas and spdf notation. Concept Introduction: Electronic configuration: The electronic configuration is the distribution of electrons of a given molecule or respective atoms in atomic or molecular orbitals. The important there rules for electronic configuration given below: Aufbau principle: This rule statues that ground state of an atom or ions electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels. If consider the 1s shell is filled the 2s subshell is occupied. Hund's Rule: The every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin. Pauli exclusion rule: an atomic orbital may describe at most two electrons, each with opposite spin direction.

Definition Definition Number of protons in the nucleus of an atom. It uniquely identifies an element, as the number of protons determines the element's properties. The periodic table of elements is arranged based on increasing atomic numbers, allowing scientists to easily locate and study elements.

Interpretation Introduction
Interpretation:
The electron configuration of Americium (Am) has to be depicted using noble gas and spdf notation.
Concept Introduction:
Electronic configuration: The electronic configuration is the distribution of electrons of a given molecule or respective atoms in atomic or molecular orbitals.
The important there rules for electronic configuration given below:
Aufbau principle: This rule statues that ground state of an atom or ions electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels. If consider the 1s shell is filled the 2s subshell is occupied.
Hund's Rule: The every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.
Pauli exclusion rule: an atomic orbital may describe at most two electrons, each with opposite spin direction.
Addition of one electron gives the bromine atom a (less or more) stable electron configuration of [Kr], the noble gas next to it in the periodic table.Addition of an electron to a barium atom would produce a (less or more) stable electron configuration since it does not achieve the configuration of a nearby noble gas.
There are many chemical concepts to explain the behavior of electrons. Electron affinity and ionization energy are two such concepts in chemistry.
1)Determine the group of element R
2)Determine the electron configuration of element R.
A group of students at College of the Canyons conducted an experiment. Two reactors contained different reagents.
Reactor 1: sodium metal + argon gas
Reactor 2: sodium metal + chlorine gas
When the reactor was heated, reactor 1 did not show a chemical reaction between the sodium metal and argon gas. However, reactor 2 showed a vigorous reaction between sodium metal and chlorine gas to form sodium chloride at the same reaction condition.
A) Write the electron configurations (noble-gas core notation) each for argon and chlorine atom.
Ar: ____________________
Cl: _____________________
B) Explain the difference in the reactivity of the gases with sodium metal.
Hint: Use the electron configurations in A).
