The charge of an electron is always −1.602176487(40)×10−19 Coulomb. If an electron is ejected from it's orbital the energy it absorbs is in the form of kinetic energy i.e. how fast it moves. If the electron goes back into an orbital it will only be allowed in an orbital that allows for it's energy. If an atom has an electron and that electron absorbs the energy from an incoming photon it may jump up to a higher orbital or it may be ejected. The ejected electron is the principle of the photo-electric effect.

What are the Three examples of properties that are quantized at the scale of an electron?
Electrical charge is quantized. (negative in an electron, as an electron has exactly -1 fundamental unit of charge) The other two would be the energy levels in the atoms and the emitted energy.
What is quantum of electric charge?
The quantum of electric charge is the smallest unit of electric charge, carried by a single electron or proton. It is approximately equal to 1.602 x 10^-19 coulombs. This value determines how charges are quantized in nature.
Does an electron or proton have a larger charge?
No. The electron and proton have the same amount of charge. Its just that the electron's charge is negative and the proton's charge is positive.
Is the charge of a electron always equal to the charge on a neutron?
The charge on an electron is never equal to the charge on a neutron. An electron carries one negative charge and a neutron has no net charge.
The charge on an electron?
The charge on an electron is -1.602 x 10^-19 coulombs.

What is meant by saying charging is quantized?
Electric charge comes in multiples of an electron , 1.6E-19 Coulombs.
What did Robert milikan discover?
Millikan's oil-drop experiment demonstrated that charge is quantized, and that the quantum of charge ... the 'elementary' charge ... is 1.6 x 10-19 Coulomb.
To say that electric charge quantized is to say that the charge on an object is?
restricted to discrete multiples of a fundamental unit of charge (elementary charge). This means that charge can only exist in specific, whole number multiples of this unit, and cannot exist as a continuous range of values.
What is quantum of electric charge?
The quantum of electric charge is the smallest unit of electric charge, carried by a single electron or proton. It is approximately equal to 1.602 x 10^-19 coulombs. This value determines how charges are quantized in nature.
What was the significance of the oil drop experiment conducted by Millikan in determining the charge of an electron?
The oil drop experiment by Millikan was significant in determining the charge of an electron because it allowed for the measurement of the charge of individual electrons. By observing the motion of oil droplets in an electric field, Millikan was able to calculate the charge of each droplet and determine that the charge was always a multiple of a fundamental unit, which turned out to be the charge of a single electron. This experiment provided a precise value for the charge of an electron and helped to establish the concept of quantized electric charge.
What does is mean to say a charge is quantized?
It means the charge is an integer multiple of some basic charge. If the charge consists of a certain number electrons, you can have 1 electron, 2 electrons, 3 electrons, etc., but you can't have 1.5 electrons, or pi electrons.
Why charge is quantized?
Charge is quantized because it is always found in discrete amounts, typically in units of the elementary charge, e. This quantization of charge is a fundamental property of matter observed in experiments and explained through theories like quantum mechanics. The existence of quantized charge leads to fundamental physical phenomena, such as the Coulomb force between charged particles.
Based on the data gathered in Millikan's oil-drop experiments the concept of atomic structure was modified Which of the following aspects of the structure of atom was validated by these experiment?
Millikan's oil-drop experiments validated the existence of discrete, quantized electrical charges on particles within the atom. This supported the idea proposed by Thomson that electrons are fundamental particles with a specific charge.
What charge does an electron have?
An electron has a negative charge.
Does an electron have a positive charge?
No, an electron has a negative charge.
What is meant by quantization in physics?
When a quantity is "quantized," it means that the quantity exists in discrete indivisible units. For example, the magnitude of electric charge is quantized, and the quantum of electric charge is the charge of the electron e. There is no known free particle with a charge of 1/2 e or 9.1254e, only particles with charges of 1e, 2e, 5e, 99e, 423425e, etc.There are numerous other quantities that can be quantized including angular momentum, energy, and even electrical conductance.
