The excited atom can be described as electrically neutral because from its electron configuration ;
From the electron configuration 2-7-2 the number of electrons equals ( 2 + 7 + 2 ) = 11 electrons, also the number of protons will be = 11 for the atom to be neutral. While the number of Neutron is not significant in the positivity or negativity of atoms.
The subatomic particles contained in an atom are protons, neutrons and electrons ( which are present in the outer most shell ) and represents the electron configuration of an atom. while the number of neutrons is determined by the Isotope.
Hence we can conclude that The excited atom can be described as electrically neutral because from its electron configuration ; The number of electrons = Number of protons .

Answer:
Number of electrons: 11
Number of protons: 11
Number of neutrons : not enough information.
Explanation:
an atom contains sub atomic particles electrons, protons and neutrons.
Electrons are present in the outer shells.
The given atom contains eleven electrons.
The atom is neutral so the number of electrons will be equal to number of protons. The number of protons will be 11.
The number of neutrons will depend upon the type of isotope.
Which describes a way to speed up the collisions between hydrogen and oxygen molecules to produce more water?
a. Use a less-intense source of heat on the reactants.
b. Maintain the same temperature of the reactants.
c. Place the reactants in a smaller container.
d. Reduce the concentration of the reactants.
Answer: C place the reactants in a smaller container
Explanation: took the quiz
colloids
solute
precipitant
Answer: The substance which is dissolved in a solution is called solute.
Explanation:
Solution is made up two parts:
1) Solute : The substance which is dissolves in a solvent to give a solution.
2) Solvent : The liquid substance in which solute is dissolved is known as solvent.
Solution = Solute + Solvent
For example : Salt as solute and water as solvent in salt solution.
Sodium is a very highly reactive metal that does not occur in free state in nature.
Sodium is a group 1 element. It has a very negative electrode potential which implies that it is highly reactive. Being a highly reactive element, sodium can not occur in free state in nature. It always occurs in combined form as compounds.
Hence, it is impossible to pick up sodium from any secret river in the mountains. Sodium metal is highly reactive hence it has to be stored under paraffin oil. The whole set up is indeed a scam.

Answer:
Explanation:
The reason this is a scam is because they are selling sodium and to sell this product you must have a licence to do so. And secondly, you cant tell the reader that it is from a secret river and sell them a product that reacts when it touches water.
