I think B or D because an eye obviously doesn't have a lense, mirror..maybe sorry for not giving u straight forward response
Electrons are responsible for the transfer of charge.
Electric energy converted to light energy
Explanation:
A column on the periodic table represents a period.
These are some of the variations observed across a period;
- Atomic radii decreases progressively from left to right due to the progressive increase in the nuclear charge without an attendant increase in the number of electronic shells.
- Ionization energy increases progressively from left to right due to decreasing atomic radii.
- Electronegativity increases from left to right.
- Electropositivity decreases across a period.
