The ground state electron configuration of aluminum is 1s² 2s²2p⁶ 3s² 3p¹

The ground state electron configuration of lithium is  1s² 2s¹

The ground state electron configuration of phosphorous is  1s² 2s²2p⁶ 3s² 3p³

The ground state electron configuration of scandium is  1s² 2s²2p⁶ 3s² 3p⁶3d¹ 4s²

In the ground state Al has 3 valence electrons, 2 electrons in the 3s orbital and 1 electron in the 3p orbital. The valence shell of Al is 3.

How does ph affect photosynthesis?
liraira [26]
Photosynthesis is the process by which plants create their food. It involves the operation of enzymes in the plant cells , and they work best at certainpH levels. ... Thus, as the plant's pH drifts away from the best pH, the rate of photosynthesis will decrease.

Which response includes all of the following processes that are accompanied by an increase in entropy?
dlinn [17]

Answer:

1 and 3.

Explanation:

The entropy measures the randomness of the system, as higher is it, as higher is the entropy. The randomness is associated with the movement and the arrangement of the molecules. Thus, if the molecules are moving faster and are more disorganized, the randomness is greater.

So, the entropy (S) of the phases increases by:

S solid < S liquid < S gases.

1. The substance is going from solid to gas, thus the entropy is increasing.

2. The substance is going from a disorganized way (the molecules of I are disorganized) to an organized way (the molecules join together to form I2), thus the entropy is decreasing.

3. The molecules go from an organized way (the atom are joined together) to a disorganized way, thus the entropy increases.

4. The ions are disorganized and react to form a more organized molecule, thus the entropy decreases.
