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

Why is the liquid oxygen machine producing less liquid oxygen than normal?
Nataly_w [17]

Answer:

Liquid oxygen evaporates at only a slightly higher temperature than liquid nitrogen because they have similarly low attraction between molecules. This would mean less liquid oxygen is coming out of tank 3 because some of it is evaporating as a gas instead.

Leviafan [203]

Answer:

52.00 AMU

Explanation:

(49.946 * 0.043) + (51.941 * 0.838) + (52.941 * 0.095) + (53.939 * 0.024) = 51.998

Make sure to round, 52.00 AMU.
