D Question 10 Why is Bra smaller atom than As? Br is actually larger than As because it has more protons. As is larger because it has more protons and electrons. Br has more protons to pull the electrons in closer. Br is smaller because it has less protons and electrons making it smaller. Br is actually larger than As because it has a larger atomic mass.

Ionization energy (Ei) is the amount of energy required to remove an electron from a neutral...
Ionization energy (Ei) is the amount of energy required to remove an electron from a neutral gaseous atom or gaseous ion. Electrons are attracted to the positively charged nucleus; therefore removing an electron requires energy. The process is endothermic, and so ionization energies have a positive value. The first ionization energy (Ei1) is the energy associated with the removal of an electron from the neutral gaseous atom. The reaction is represented for the generalized atom X as X→X++e− The amount...
