The Number of Protons from Electrons. For a neutral atom, the number of protons and the number of electrons are equal. This is what makes the atom charge-free. Therefore, you can determine the number of protons if the number of electrons is given. For example, identify the element of an atom with 54 electrons.

Hydrogen ion. A hydrogen ion is created when a hydrogen atom loses an electron. A positively charged hydrogen ion (or proton) can readily combine with other particles and therefore is only seen isolated when it is in a gaseous state or a nearly particle-free space. [1]
29 lip 2022 · Describe the locations, charges, and masses of the three main subatomic particles. Determine the number of protons and electrons in an atom. Write and interpret symbols that depict the atomic number, mass number, and charge of an atom or ion. Define the atomic mass unit and average atomic mass.
30 sty 2023 · The periodic table is arranged in columns and rows based on the number of electrons and where these electrons are located, providing a tool to understand how electrons are distributed in the outer shell of an atom.
Number of protons = number of electrons = atomic number. Number of neutrons = mass number – atomic number. Key fact. Remember that Protons are Positive, and Neutrons are Neutral....
Atoms are electrically neutral with the same number of positively charged protons and negatively charged electrons. When the numbers of these subatomic particles are not equal, the atom is electrically charged and is called an ion. Atomic or ionic charge = number of protons − number of electrons.
