Which of the following are always larger than the neutral atoms from which they are formed?
frosja888 [35]
<span>A. positive ions : Positive ions are formed when a neutral atom loses electrons. When neutral atoms lose electrons, the ions formed are always smaller than the neutral atoms.


B. negative ions : Yes. When the neutral atoms gain electrons to form negative ions, they always become larger, because the addition of one electron increases the electrostatic repulsion of the outermost electrons, forcing them to drift apart.


C. cations  No. Cation is the same that positive ion.

D. none of the above </span>

Which piece of laboratory glassware did you find to be more efficient for the solvent extraction procedure, and why?
Anna [14]

Answer:

Condenser

Explanation:

Condenser is highly efficient when dealing with the vapors of the product are need to be liquified. It is mostly automated and regularly condenses the incoming vapors into liquid. It is very easy to use. All we have to do it to attach incoming and outgoing flow pipes and constantly monitor the flow of cold water through the condenser. It is made up of special kind of PYREX glass so that it won't break when dealing with steam.

What is the second quantum number of the 3p1 electron in aluminum 1s22s22p63s23p1?
Brut [27]
There are 4 quantum numbers that can be used to describe the space of highest probability an electron resides in.
First quantum number is the principal quantum number- n , states the energy level.
Second quantum number states the angular momentum quantum number - l,
states the subshell and the shape of the orbital
values of l for n energy shells are from 0 to n-1
third is magnetic quantum number - m, which tells the specific orbital.
fourth is spin quantum number - s - gives the spin of the electron in the orbital

here we are asked to find l for 3p1
n = 3
and values of l are 0,1 and 2
for p orbitals , l = 1
therefore second orbital for 3p¹ is 1.
