Sodium is the 11th element in the periodic table so it will have 11 electrons (if you're not sure if something is right always check how many electrons they're are it's like checking your work in math). There are 4 energy "types" in the periodic table: S,P,D and F. Starting from the top left you are in the first energy level 1 (in the S area which is always the first two elements on the left of the table before the transition metals) and there are two elements (hydrogen and helium) so you have 1s^2 then you go down to the second column and you have the first two elements which are Lithium and Beryllium so your next config is 2s^2. Now you have more elements on the left and those are in the "P energy section" and there are 6 elements there so you put 2p^6. Now you move down again and you're in the 3rd energy level and sodium is the 1st element and so you only need to put 3s^1. Your econfig is 1s^2 2s^2 2p^6 and 3s^1

Which of the following statements is true of glare control?

galina1969 [7]

The correct option is B.
Indirect lighting refers to fixtures which direct the light upward to bounce off the wall or ceiling to light a room. This type of lighting is diffusely reflected and create less glare compare to direct lighting. Direct lighting usually direct the light downward, directly on to the surface below to provide illumination.

Organic acids and bases in their ___________ form are soluble in organic solvents, but the corresponding _________ are more wate

gizmo_the_mogwai [7]

Answer:

a. neutral

b. salts

c. salt

Explanation:

Organic salts are a dense number of ionic compounds with innumerable characteristics. They are previously derived from an organic compound, which has undergone a transformation that allows it to be a carrier of a charge, and that in addition, its chemical identity depends on the associated ion.

Organic salts are usually stronger acids or bases than inorganic salts. This is because, for example, in the amine salts, it has a positive charge due to its bond with an additional hydrogen: A + -H. Then, in contact with a base, donate the proton to be a neutral compound again

RA + H + B => RA + HB

H belongs to A, but it is written as it is involved in the neutralization reaction.

On the other hand, RA + can be a large molecule, unable to form solids with a crystalline network stable enough with the hydroxyl anion or oxyhydrile OH–.

When this is so, salt RA + OH– behaves as a strong base; even as basic as NaOH or KOH

Most atoms have no net charge because they have

Ne4ueva [31]

Atoms have no electric charge because the protons and electrons "cancel out" each others charges. Neutrons have no charge. What is the atomic number of an element? The atomic number is the number of protons in the atom's nucleus.

Hope this helps have a great day :)
