Electron Configuration is what?
The arrangement of electrons in an atom.
100
Which type of bond results from the SHARING of electron pairs between two atoms?
Covalent bond
100
How many electrons does it take to completely fill a d orbital and f orbital combined?
10 + 14 = 24 electrons
200
What element is least electronegative O or Cs?
Cs
200
Name the formula for carbon dioxide
CO2
200
What 2 elements are rule breakers in the D block?
Copper and Chronium
200
What do ionic bonds form?
Cations and anions
200
Why do ionic compounds dissolve in water?
Water is a polar molecule. The positive cation from the ionic solid is attracted to the negative end of the water molecule (oxygen) and the negative anion of the ionic solid is attracted to the positive end of the water molecule (hydrogen).
