An electron in an atom moves from a ground state to an excited state when the electron energy increases
Excitation in physics is the addition of a number of discrete energies (called excitation energies) to a system — such as the nucleus of an atom, atom, or molecule — so as to produce a change, usually from the lowest energy state (ground state) to one of the higher energies (excited state).
In nuclear, atomic and molecular systems, excited states do not continue to be distributed but instead have certain discrete energy values. Thus, external energy (excitation energy) can be absorbed in discrete quantities.
Excitation energy is stored in excited atoms and the nucleus that emits light is usually seen from atoms and as gamma radiation from the nucleus because they return to the ground state. This energy can also be lost by collisions.
In the nucleus, energy is absorbed by protons and neutrons which are transferred to an excited state. Within a molecule, energy is absorbed not only by electrons, which are very enthusiastic for higher energy levels but also by whole molecules, which are highly excited for the discrete states of vibration and rotation.

Answer:
Li2O+H2O---->(2)LiOH
Explanation:
you have to balance the equation and not all the blanks have to be filled all the time but if it makes it easier for you in the first 2 question marks you can put a 1 which isnt necessary but if ur a visual person it will help.
hope this helps im litterally learning the same thing as u lol
Answer:
1,1,2
Explanation:
this was correct for me, if it wasnt correct check if youre on the right question
Given:
128g sample ofwater
2808J of heatenergy
Required:
Change intemperature
Solution:
This can be solvedthrough the equation H = mCpTwhere H is the heat, m is the mass, Cp is the specific heat and T is the change in temperature.
The specific heatof the water is 4.18 J/g-K
Plugging in thevalues into the equation
H = mCpT
2808J = (128g)(4.18 J/g-K) T
T= 5.25 K
(2) silver (4) xenon
The element that has atoms that can form halide ions is iodine.
Halogens are nonmetals. At room temperature, fluorine and chlorine are gases, bromine is a liquid and Iodine and astatine are solids. Halogens are very reactive, the reactivity decreases from fluorine to astatine. Halogens do not exist in elemental form in nature. Astatine isotopes are radioactive with short half-lives.
One of the definitive properties of halogens is that they are highly reactive. Due to this nature, they can form different compounds such as halides, interhalogens and polyhalogenated compounds. We will look at them in brief below.
These are compounds formed by the reaction of halogens with metals. Metal halides can be highly ionic compounds, monomeric covalent compounds or polymeric covalentcompounds.
Therefore, The element that has atoms that can form halide ions is iodine.
