Answer:

The element is oxygen.

1s² 2s² 2p⁴

Explanation:

Let's consider the electron configuration of the excited state.

1s² 2s² 2p³ 3s¹

According to the Aufbau principle, the electron in 3s should occupy the shell with lower energy. The ground-state electron configuration is:

1s² 2s² 2p⁴

The differential electron is in the level 2. Then, the element is in the period 2.

The electrons in the last level are 2 + 4 = 6. Then, the element is in the group VIA or 16.

The element is oxygen.

At which type of tectonic plate boundary is a volcano least likely to occur?
Katena32 [7]

Answer:

A divergent boundary is when the plates move apart from each other. When the plates part, magma from under either plate rises and forms a volcano. A hotspot is the third place a volcano can form. This particular type is the least common.
