If an atom of Copper has a charge of +4 how many electrons and protons does it have
P=29
E=25
Which nonmetals are highly unreactive?

Which non metal is more reactive, Chlorine or Selenium
What is Chlorine
What is the electron configuration for Mercury (use the short hand)
[Xe]6s2 4f14 5d10
How many unpaired electrons does Cobalt have
what is 4
If Bromine has a charge of -1 how many protons and electrons
P=35
E=36
If I have a -3 charge on an atom do I have more electrons then protons or more protons then electrons?
What is more electrons then protons
Why does the atomic radius of atoms increase going right to left
What is there are more protons on the right most atoms that pull the electrons closer to the nucleus then on the left side, so the atoms on the left have a large electron configuration.
What is the element for [Kr]5s2 4d10 5p1
How many valence electrons does Cesium have
Why can we not change the number of protons?
Because it defines the element
Mercury- give the symbol, atomic number, protons, neutrons and electrons when the mass is 201 and it has a +5 charge.
Hg
A#=80
P=80
N=121
E=75
Why does the atomic radius increase doing down the periodic table
Because there are more energy levels as you go down, so the radius increase
