Beryllium has an atomic number of 4, so a beryllium atom has 4 protons in its nucleus.

Since the charge of 1 proton is +1 and neutrons in the nucleus have 0 charge, the correct answer is (4) +4.

Hope this helps~

Answer:

The light emitted by a light bulb is a form of radiation that occurs when the filament heats up and its thermal emission gains enough energy to move into the visible spectrum.

Explanation:

Light bulbs contain a filament which is heated up electrically. When this filament is heated up,energy in the form of heat is imparted to the electrons in the filament.

This thermal excitation of electrons ultimately leads to emission of light in the viable spectrum. This light is now radiated through a light bulb.
