Answer:

ii) the energy of the electron on the outer shell

iv) the overall size of an orbital

Explanation:

There are four quantum numbers to define the position and energy level of an electron in an atom

a) Principal : The principal quantum number (n) is to know the energy of an electron in an atom and its possible distance from the nucleus.

b) Azimuthal: It refers to the shape of the subshell or orbital of the electron and thus the angular distribution.

c) Magnetic: It refers to the number of orbits and their orientation in the subshell.

d) spin: It refers to the spin of the electron.

I’m confused because this is the answer key and I don’t know how they got the answer to number 1)

Question One

It's more a question of unscrambling what is there. The answer is correct.

If you look at your periodic table, there is such an element as Na which I suspect might be the problem.

It has an atomic mass of 23. It's atomic number is 11 which means it is the 11th member (by mass) on the periodic table. The other 2 are oxygen and hydrogen.  So Oxygen has an atomic mass of 16 and Hydrogen has an atomic  mass of 1.

Oxygen is number 8 on the periodic table and hydrogen is number 1.

Molecular Mass

Na = 23

O = 16

H = 1

Total 40, just as the answer key says. I've probably given you more than you wanted to know, but if you still have trouble, leave a note.

If the hydroxide ion concentration of a solution is 3.26 x 10-6 M, is it an acidic or a basic solution?
sladkih [1.3K]

Answer: It is a basic solution with pH =8.51

Explanation:

We were given that hydroxide ion concentration [OH-] as 3.26 x 10-6 M

But We know thar

[OH-] [H+] = 1 × 10^-14

To get the Hydrogen ion [H+] concentration, we have that

[H+] = 1 × 10^-14 M/[OH-]

= 1 × 10^-14 M/3.26 x 10-6 M

    =  3.067 x 10^-9 M

But, pH = - log [H+]

Therefore,

pH = - log (3.067 x 10^-9)

pH=8.51

when  pH > 7, The solution is basic, therefore a solution with pH =8.51 is basic.
