Electron configurations correspond to an excited state is 1s₂, 2s₂, 3p₁.The electrical configuration 1s₂, 2s₂, 3s₁ demonstrates that the atom is in the excited state.
What is electronic configuration ?The distribution of an atom's or molecule's electrons in atomic or molecular orbitals is known as the electron configuration in atomic physics and quantum chemistry.
An electron is in an excited state when it momentarily possesses an energy level higher than its ground state. If an electron receives more energy, such as when it absorbs a photon, or packet, of light, or collides with an adjacent atom or particle, it can become excited.
The primary distinction between a system's ground state and excited state is that a system's ground state is any condition in which its electrons are at their lowest potential energy levels, whereas an excited state is any state in which they are at an energy greater than the system's ground state.
Thus option A is correct.

corresponds to excited states whereas [tex]1s^2\ 2s^2\ 3p^6[/tex] corresponds to ground state. The correct answer is option 2.
The electron configuration of an atom describes how its electrons are distributed among the various energy levels and orbitals.
The electron configuration [tex]\rm 1s^2\ 2s^2\ 3p^1[/tex] corresponds to an excited state. This configuration indicates that one of the electrons in the 2p orbital has been excited to a higher energy level.The electron configuration [tex]1s^2\ 2s^2\ 3p^6[/tex] is the ground state configuration of the noble gas argon (Ar).The electron configuration [tex]\rm 1s^2\ 2s^2\ 2p^4\ 3s^1[/tex]corresponds to an excited state. This configuration indicates that one of the electrons in the 3s orbital has been excited to a higher energy level.The electron configuration [tex]\rm [Ar] 4s^2\ 3d^5\ 4p^1[/tex]corresponds to an excited state. This configuration indicates that one of the electrons in the 4p orbital has been excited to a higher energy level.Therefore, the electron configurations [tex]\rm 1s^2\ 2s^2\ 3p^1[/tex], [tex]\rm 1s^2\ 2s^2\ 2p^4\ 3s^1[/tex], and [tex]\rm [Ar] 4s^2\ 3d^5\ 4p^1[/tex]correspond to excited states, while the electron configuration [tex]1s^2\ 2s^2\ 3p^6[/tex] is the ground state configuration of argon.

Indicate whether each statement is true or false: a. Substitutional alloys tend to be more ductile than interstitial alloys. b. Interstitial alloys tend to form between elements with similar ionic radii. c. Nonmetallic elements are never found in alloys.
Answer:
Substitutional alloys tend to be more ductile than interstitial alloys. true
Interstitial alloys tend to form between elements with similar ionic radii.false
Nonmetallic elements are never found in alloys. false
Explanation:
Substitutional alloys consists components having similar atomic(ionic) radii as well as common bonding characteristics. In interstitial alloys, atoms in interstitial positions must have a much smaller covalent radius than the solvent atoms. Interstitial atoms are generally less ductile than substitutional alloys.
Nonmetals are found in alloys. For instance, carbon is a component of the common alloy called steel.

For the elements in the "f-block," how is the row number related to the principal energy level for the last orbital notation of their electron configurations?"
Answer:
See explanation
Explanation:
Given that the row number is the same as the period or energy level(shell) in which the electron is found.
If we designate this row number as "n", we know that the highest principal energy level for the f orbitals is obtained as (n-2) f.
Thus, we obtain the highest principal energy levels for the "f block" elements by subtracting 2 from the row number.

how dose the scientist know the substances goes through a change of state during the time period labeled B on the graph?
Answer:
The temperature remains constant
Explanation:
In a plot of temperature against time, it is easy to spot the points on the graph where a change of state is taking place.
During a change of state, the temperature does not not change with time. These are points that are plateaus on the temperature-time graph.
This is because, during phase change, the heat that is added is used in breaking intermolecular forces therefore a temperature change is not observed until the phase change is complete.
