How much neutrons, protons and electrons does al3+ have?

Protons = 13

Electrons= 10

Neutrons = 14

Explanation: This problem is an ion of Al which has a charge of +3

For this ion the atomic number for Al is 13 and its mass number is 27.

The atomic number indicates the number of protons which is 13. The number of electrons is changed due to loss of electrons since it was ionized. It loses 3 electrons so the total number of electrons is 13-3 = 10.

The number of neutrons can be calculated using

Atomic mass - atomic number

27- 13 = 14 neutrons

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

d.) circle motion requires a force to give it a centripetal acceleration.
