Which atom attracts electrons more strongly?
cesium (cs)
bromine (br)
which atom loses an electron more readily?
sodium (na)
chlorine (cl)

Explanation:

1.    Cesium (Cs) is a group 1 element and it has electronic configuration .

On the other hand, bromine is a group 7 element and it has electronic configuration .

Since, Cs is a metal so it will readily lose 1 electron but bromine being a non-metal needs 1 electron to completely fill its orbital.

Hence, bromine atom will attract electrons more strongly.

2.   Sodium (Na) is a a group 1 element and it has electronic configuration .

Whereas, chlorine is a group 7 element and it has electronic configuration .

So, sodium is a metal hence, it readily loses its one electron and chlorine being a non-metal will attract one electron in order to completely fill its orbital.

Thus, we can conclude that sodium (Na) atom loses an electron more readily.
