how to find the electron of element
Answers
Answer:
The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules.
The number of protons in the nucleus of the atom is equal to the atomic number (Z).
The number of electrons in a neutral atom is equal to the number of protons.
Answer:
Protons are particles in the nucleus of an atom that have a positive charge equal to +1. Electrons are particles that have a negative charge equal to -1. Therefore, an element in a neutral state will have the same number of protons and electrons.
For example, boron (B) has an atomic number of 5, therefore it has 5 protons and 5 electrons.
However, if the element includes a negative or positive ion, then the protons and electrons will not be the same. You will have to calculate them. The ion number will appear as a small superscript after the element.
