The protons and neutrons that make up the nucleus are much heavier than an electron. Protons and neutrons are almost the same weight as each other and are just over 1800 times as heavy as an electron. there are the same number of electrons as protons in a neutral atom and typically a number of neutrons as well, so the percentage by weight of electrons is very small.
What else can I help you with?
Why does the number of electrons have little effect on the overal mass of an atom?
Electrons are very light. Protons are approx. 1800 X the mass (rest mass to be presice). Neutrons are about the same mass a protons. So the mass of all the electrons has little effect.
If an atom contains 15 electrons it will also have 15?
Protons, because electrons are equal to the atomic number and protons are equal to the number of electrons.
What determines the overall charge of an element if an electron charge is negative and a proton has a positive charge?
The overall charge of an element is determined by the number of protons in the nucleus. Protons have a positive charge, while electrons have a negative charge. In a neutral atom, the number of protons is equal to the number of electrons, resulting in no overall charge.
The overall charge of an atom is negative if the number of electrons is less than the number of protons?
No, the overall charge of an atom is negative only if the number of electrons is greater than the number of protons. An atom becomes negatively charged when it gains extra electrons, causing an imbalance in the positive charge of the protons and the negative charge of the electrons.
Why do you calculate the number of electrons by the atomic mass and number?
You calculate the number of electrons by the atomic mass and number because elements have the same number of electrons as they do protons. The atomic number tells you the number of protons, which is also the number of electrons in a neutral atom. By using the atomic mass to find the number of neutrons, you can determine the overall charge and number of electrons in an atom.

In an atom with a neutral overall charge the number of protons is equal to the .?
Number of electrons.
What is the overall charge of the oxygen atom?
The overall charge of any atom is 0. This is because the overall charge is number of protons - number of electrons. For every atom the number of electrons is equal to the number of protons so it is 0.
How do you find the overall of an atom?
(Atomic number) - (Number of electrons present) = (overall electrical charge of atom)
Atomic mass is number of protons added to the number of neutrons. Why is number of electrons not included in it?
Because electrons are very light particles and do not effect the mass, if proton and neutrons are elephant then electrons are ants , how ants effect the mass and weight of elephant ?
If an atom contains 15 electrons it will also have 15?
Protons, because electrons are equal to the atomic number and protons are equal to the number of electrons.
What determines the overall charge of an element if an electron charge is negative and a proton has a positive charge?
The overall charge of an element is determined by the number of protons in the nucleus. Protons have a positive charge, while electrons have a negative charge. In a neutral atom, the number of protons is equal to the number of electrons, resulting in no overall charge.
Why the overall charge of the oxygen atom is zero?
The overall charge of any atom is 0. This is because the overall charge is number of protons - number of electrons. For every atom the number of electrons is equal to the number of protons so it is 0.
The overall charge of an atom is negative if the number of electrons is less than the number of protons?
No, the overall charge of an atom is negative only if the number of electrons is greater than the number of protons. An atom becomes negatively charged when it gains extra electrons, causing an imbalance in the positive charge of the protons and the negative charge of the electrons.

How many electrons does an atom of this element contain?
The number of electrons in an atom of an element is equal to its atomic number, which is the number of protons in its nucleus. For example, if the atomic number of the element is 6, it contains 6 electrons. In a neutral atom, the number of electrons matches the number of protons, ensuring overall electrical neutrality.
In a neutral atom what is the relationship between the number of protons and electrons?
They are equal.
