It has a -1 charge, so it would gain one!
First, let us define Electronegativity. Electronegativity is "the ability of an atom to attract electrons." In addition, electronegativity increases in elements from left to right, while on the other hand, electronegativity decreases from top to bottom in an element group. It decreases because the atomic radius increases as we go downward an element in the group.
<u>Answer:</u> The correct answer is Option d.
<u>Explanation:</u>
Nuclear fission reaction is defined as the reaction in which 1 heavier nuclei splits into two or more smaller nuclei.
As, nuclear fission reactors require a large amount of energy to split the nucleus, hence it is bombarded with a particle in order to star the reaction.
In a nuclear reaction, a large fissile atomic nucleus like Uranium-235
or Plutonium-239
when absorbs a neutron, it undergoes nuclear fission reaction.
Hence, in the given options, uranium-235 is absorbing a neutron. Therefore, the correct answer is Option d.
The correct answer is C. We know this is true since the number of protons an atom has is its atomic number. Since this atom has 9 protons, look for the element on the periodic table that has an atomic number of 9. The element that has an atomic number of 9 is flouring.
I hope this helps.
