Explanation:
solution:
The atomic number of Ni is 28 (periodic table), therefore the number of protons is 28. The atomic weight is 59 therefore the number of neutrons plus protons is 59. 59-28=31 neutrons
I'm assuming the Ni has a 2+ charge, so the number of electron would be 26.
Answer:
A
Explanation:
Air lower in the atmosphere is more dense than air above, so air pressure down low is greater than air pressure higher up. (Remember those acrobats; there's a lot more pressure on the one on bottom than on the one on top.) Temperature also makes changes in air pressure.
