A boron atom has three electrons in its second energy level.

The second shell in an atom contains 4 orbitals and can hold up to 8 electrons.
eight

A star at the celestial equator will move 15 degrees in altitude per hour, and 15 arcseconds in 1 second of time. This is because the celestial equator intersects the celestial sphere at 90 degrees from the north and south celestial poles, so the stars appear to move in circles around the celestial poles.
The second orbit of an atom can hold up to 8 electrons.
An atom with seven electrons will have five electrons in the second energy level.
The second shell is 2S, 2P which can hold 8 total (2+6).
3. 2 in the first shell, 1 in the second
5. If it is more or less than 5 protons then it is not boron.
a sulfur atom has 3 energy levels. 2 on the first. 8 on the second and 6 on the third
