The ability to attract an electron in a chemical bond
electronegativity
electron affinity
metallic character
ionization energy
The energy it takes to remove an electron from an atom in the gas phase
electron affinity
electronegativity
metallic character
ionization energy
Ionization energy increases
from L to R and from bottom to top
from L to R and from top to bottom
from R to L and from bottom to top
from R to L and from top to bottom
Atomic radius decreases from left to right across a period because from left to right there is
increasing number of valence electrons
increasing shielding
increasing effective nuclear charge
increasing number of protons in the nucleus
The element with the highest electronegativity is -
At
F
Cl
Br
The ionization energy of Na is larger than Cs because...
Na has a greater effective nuclear charge
Na has fewer energy levels and less shielding
Cs has a greater effective nuclear charge than Na
Cs has more valence electrons than Na
Fluorine has a smaller atomic radius than B because...
F has more valence e- than B
F has more shielding than B
F has a larger atomic number than B
F has a greater effective nuclear charge than B
