Any atom is most stable when it’s outermost energy level contains
slamgirl [31]

Explanation:

Atoms are at their most stable when their outermost energy level is either empty of electrons or filled with electrons. Sodium atoms have 11 electrons. Two of these are in the lowest energy level, eight are in the second energy level and then one electron is in the third energy level.

Calcium chloride contains calcium and chloride ions. Write the ground-state electron configuration for the calcium ion.
Drupady [299]

Answer:

1s2 2s2 2p6 3s2 3p6

Explanation:

Calcium is the 20th element. It has 20 electrons in it's neutral state. The electronic configuration is given as;

1s2 2s2 2p6 3s2 3p6 4s2

However in the compound; calcium chloride, it does not exist in it's neutral state.

CaCl2 --> Ca2+   +   Cl-

In Ca2+ state, it has lost two electrons, The total number of electrons becomes; 20 - 2 = 18 electrons.

The electronic configuration is given as;

1s2 2s2 2p6 3s2 3p6

Calculate the Ka of your acetic acid solution. Discuss this calculation. Based on the value of Ka, is acetic acid a strong acid
lord [1]

Based on our knowledge of strong and weak acids, we can confirm that the Ka value for acetic acid will be relatively low since it is a weak acid.

Acids can be strong or weak. This is determined by its <u><em>tendency to break apart into ions or stay together to form molecules.</em></u> Although somewhat counter-intuitive, strong acids are those that are most likely to break apart and therefore contain a <em><u>high number of </u></em><em><u>ions </u></em><em><u>within their solutions</u></em>.

Weak acids, on the other hand, are those that<em><u> tend to stay together in the form of </u></em><em><u>molecules </u></em><em><u>and therefore possess very </u></em><em><u>low ion counts </u></em><em><u>in their solutions.</u></em> The acid dissociation constant, Kₐ, is used to measure whether an acid is weak or strong and how much so. In the case of Acetic acid, the ka measurement will offer a low value, indicating a weak acid.
