Why would it be more difficult to inject the nucleus of uranium with a proton?
nasty-shy [4]

Answer:

Because there are already 92 protons in the

uranium nucleus, combining their repulsive power to reject the one new one. However, if the energy of the incoming proton is sufficiently great, then at extremely close distance, the uranium nucleus will attract the proton and draw it into the nucleus. This is called the strong force.

If an element has an atomic number of 20 and a mass number of 41, what is the :
iVinArrow [24]

Answer:

20 protons, 20 electrons, and 21 neutrons

Explanation:

The atomic number of an atom is the number of protons it has. If the atomic number is 20 then we know the atom has 20 protons.

•The mass number of an atom is the total number of protons and neutrons the atom contains. The mass number is 41 and the number of protons is 20, just subtract 20 from 41 and you will get the number of neutrons: 41 - 20= 21. The atoms has 21 neutrons.

•The number of electrons found in an atom is equal to the number of protons. The atoms has 20 protons which means it has 20 electrons.

So, the answer is:

20 protons, 20 electrons, and 21 neutrons
