Consider the following neutral electron configurations in which n has a constant value. which configuration would belong to the element with the most negative electron affinity, eea? view available hint(s) consider the following neutral electron configurations in which n has a constant value. which configuration would belong to the element with the most negative electron affinity, ? ns2 ns2np2 ns2np5 ns2np6

b i think it’s a water wheel turning in a stream

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

you didnt put any of the following
