What is the electron configuration of an element with a full d-block orbital in the 4th energy level?
1s22s23p63s23p64s23d10
Which elements and ions are isoelectronic with each other: Mg2+ and S, I- and Cs+, Ca2+ and F-?
I- and Cs+
Which element is a solid nonmetal at room temperature: Re, B, S, Po?
Sulfur
Why does Br- have a greater atomic radius than Sr2+?
Sr2+ has lost 2 electrons, and remains with more protons which pull the electrons in closer, while Br- gains an electron and has fewer protons than electrons, meaning the protons cannot pull the electrons as close.
