Camila and Ana Maria are arguing which one is the correct molecular formula for a compound. Camila claims that the compound should be Na2O (where Na is Na+, and O is O-2). Ana María says that it shoud be NaO3 (where Na is Na+3 and O is O-1).
Who is correct?
Camila, because the stable ions for Na and O are Na+ and O-2
Ana María, because the O atom becomes stable after gaining 1 electron, as in O-
Camila, because both Na+ and Na+3 are correct and stable ions.
Ana María, because O is electronegative, so it can attract many electrons.
This sketch shows the atomic radius trends in the periodic table. Select the correct option
Atomic radius is correct, because it grows to the left and downward.
Atomic radius is wrong, as it grows to the right and downward.
Atomic radius is wrong, because it grows from left to right.
Atomic radius is wrong, because it grows from bottom to top.
Which one(s) of the following substances aren't likely to be found
Mg2O3 (Mg = Mg+3, O = O-2)
H3O (H=+1, O = -3)
Si2F3 (Si = Si+3, F=F-2)
MgO (Mg = Mg+2, O = O-2)
NCl3 (N = N+3, Cl = Cl-)
