Why can certain kinds of light eject electrons from metals and others cant?

Electrons that are loosely bounded to the Atom, are probable to ejected by providing enough energy, that may be in the form of light(photon) of suitable energy or heat.
Protons and Neutrons are tightly bounded to the nucleus by Strong nuclear force.
and for a Light of any frequency it is unable to overcome to Strong nuclear force to eject it.

According to the particle model of light certain kinds of light cannot eject electrons from metals because?
The energy of the light is too low.
Could you use a highly intense beam of red light to eject electrons from the surface of a metal?
Yes, this is called the photoelectric effect. Discovered my Einstein.
The photoelectric effect refers to what?
The waves have to be considered as made up of small packets of energy bundles called as quanta (photons). As these photons fall on a substance they eject electrons right from the surface.
What is the ability of light to eject an electron from a metal according to albert Einstein?
This is a phenomenon known as the photoelectric effect. Light arrives at the metal and gives energy to the electrons, causing them to be ejected from the metal.
What is the noun form of the word eject?
The noun forms of the verb to eject are ejector, ejection, and the gerund, ejecting.
According to the particle model of light certain kinds of light cannot eject electrons from metals because?
The energy of the light is too low.
It takes 254 kJmol to eject electrons from a certain metal surface What is the longest wavelength of light nm that can be used to eject electrons from the surface of this metal via the photoelectr?
472nm
Is is true that the frequency of photons must be larger than a certain minimum value in order to eject electrons from the metal?
YES.
Atoms of metals do what with electrons to become stable while atoms nonmetals tend to do what to electrons to become stable?
Choices: a) eject, retain B) lose, gain c) retain,gain d) gain, lose e) lose, retain
Does the intensity of light determine whether radiation will eject electrons?
No. The wavelength of the light determines whether an electron will be ejected from an atom.
Will bright blue light eject more electrons than dim light of the same frequency?
Brighter light has more energy.
Could you use a highly intense beam of red light to eject electrons from the surface of a metal?
Yes, this is called the photoelectric effect. Discovered my Einstein.
Do radio waves cause an electron to be ejected from cobolt?
The individual photons in radio waves have way too little energy to eject electrons out of ANYTHING.

What is the Gaelic for 'eject'?
In Irish Gaelic: díchuir (eject, expell; disperse,excrete); cuir amach ('put out', emit, send, etc.) caith amach (throw out, project) In Scottish Gaelic: caith a-mach (eject) tilg-a-mach (eject) as-àitich (eject/evacuate/displace) dìobair (eject/banish/abandon) fògair (eject/exile/banish)
Red light CANNOT cause an electron to be ejected from a potassium atom because of?
the energy of red light is not sufficient to eject electrons from the valence shell of the potassium atom.
What is the past tense of eject?
Ejected is the past tense of eject.
