<u>Answer:</u> The nuclear equations for the given process is written below.
<u>Explanation:</u>
The chemical equation for the bombardment of neutron to U-238 isotope follows:

Beta decay is defined as the process in which neutrons get converted into an electron and a proton. The released electron is known as the beta particle.

The chemical equation for the first beta decay process of
follows:

The chemical equation for the second beta decay process of
follows:

Hence, the nuclear equations for the given process is written above.
Answer:
1 kg
Explanation:
prefix nano means 10^-9
kilo 10^3
mili 10^-3
centi 10^-2
the largest amount is 1 kg
Solution:
Since we have ml=-1
it shows that it has two 2e- i;e it fond in 2nd subshell in f orbital. And each subshell can hold 2 e-.
Thus the required answer is 2 electrons hold by an atom.
