Nuclear charge stays the same
Don’t know the answer choose me
What is ionic radius?
Distance from nucleus to the valence electron of ion
Distance from nucleus to the proton
Distance between inner electrons of ion
Distance between nucleus to the valence electron of atom
Which of the following is wrong for the trend of ionic size for non-metal ion?
Larger than original atom since same electron is given
Multiple repulsion between atom because electrons are taken away
Domain of electrons clouds are enlarged
Negative ions are larger than the atom from which they are formed
Which of the following has the smallest ionic size?
Mg2+
Mg
Ca2+
Ca

K, He, Ca, I
He, K, Ca, I
He, I, K, Ca
Ca, K, I, He
Which element was first discovered in the Periodic table?
Gold
Copper
Mercury
Phosphorus
Which element is the largest?
Na
K
Li
Rb
Atomic size increases across the period. This happens because as you move across the period each element has one more (a) in its nucleus than the last one.
