Question

What happens if a proton is added to lithium-7?

Answer 1

How do I do to add a proton to an atom?

Answer 2

The question is asking hypothetically what would happen if it had an extra proton

Answer 3

we can increase the atomic number, of an atom, by \(1\) unit, through this nuclear process:
\[\Large n \to p + {e^ - } + {{\bar \nu }_e}\]
namely a neutron transforms into a proton plus an electron pplus an electronic anti-neutrino
So, mass number is unchanged, whereas the atomic number is increased by \(1 \) unit:
\(Z \to Z+1\)

Answer 4

plus*

Answer 5

Well, we haven't studied the processes or anything. It is only a question about what would happen if lithium-7, which has 3 protons, 4 neutrons, and 3 electrons, had 4 protons, 4 neutrons, and 3 electrons.

Answer 6

I understand, I have written that explanation, since I like nuclear physics.
Nevertheless, after that process, we get an atom with \(4\) protons and \(3\) neutrons, and, of course \(3\) electrons

Answer 7

Does it become a different element after the change?

Answer 8

as we can see, it becomes a positive ion

Answer 9

What happens if a neutron was added to lithium-7?

Answer 10

here, we have to consider an analogous nuclear process:
\[\Large p \to n + {e^ + } + {\nu _e}\]
namely a neutron transforms into a proton plus a positron (positive electron) plu an electronic neutrino

Answer 11

so, after that process, again the mass number is unchanged, whereas the atomic number is decreased by \(1\) unit: \( Z \to Z-1\)

Answer 12

so, we get an atom with \(3-1=2\) protons and \(4+1=5\) neutrons, the same atomic number of helium

Answer 13

I see. Thank you!

Answer 14

for previous question, we get an element with the same atomic number of Berillium
