The number of protons (each has charge = +1) in an atom identify the element, e.g. hydrogen (1 proton), helium (2 protons), etc. If the number of electrons is the same, then the atom is neutral (total charge = 0).
For example, a lithium atom has three protons in the nucleus (charge = +3) and three electrons (charges -1,-1,-1). The total charge is +3 -1 -1 -1 = 0. If the number of electrons is different than the number of protons, as when lithium would lose an electron, we say the lithium atom has been ionized--it is now a lithium ion and the charge is +3 -1 -1 = +1. If the lithium ion loses another electron, we would say it is doubly ionized or twice ionized and the charge would be +3 -1 = +2.

How many electrons versus protons in an atom?
The number of electrons should = the number of protons.
How would you figure the number of protons or electrons in an atom?
The number of protons in an atom is equal to its atomic number. In a neutral atom, the number of electrons is equal to that of protons. If the atom is negatively charged, add it to the number of electrons; and if positive, subtract.
How you can use the atoms mass number and atomic number to determine the number of protons electrons and neutrons in the atom?
The numbers of protons and of electrons in an atom are both the same as the atomic number, and the difference between the mass number and the atomic number is the number of neutrons in the atom.
How many electrons and protons are there in potassium?
A potassium atom has 19 protons and 19 electrons. This is because the number of protons in an atom is equal to its atomic number, which for potassium is 19. Electrons in a neutral atom are equal to the number of protons.
What is the relationshp of protons and electrons in a neutral atom?
In any neutral atom, the number of protons = the number of electrons.
In a neutral atom the number of electrons equals the number of what?
The number of electrons should equal the number of protons, otherwise you have an ion.
How many electrons versus protons in an atom?
The number of electrons should = the number of protons.
How many protons and electrons are contained in an atom of element ruthenium?
An atom of ruthenium contains 44 protons and 44 electrons. This is because the number of protons in an atom determines its identity, and for a neutral atom, the number of protons equals the number of electrons.
How would you figure the number of protons or electrons in an atom?
The number of protons in an atom is equal to its atomic number. In a neutral atom, the number of electrons is equal to that of protons. If the atom is negatively charged, add it to the number of electrons; and if positive, subtract.

What is the relationshp of protons and electrons in a neutral atom?
In any neutral atom, the number of protons = the number of electrons.
How many electrons has an atom?
An atom has the same number of electrons as it does protons, and the number of protons determines what element it is.
What must be true of the number of protons and the number of electrons in an atom if the atom has no charge?
The number of protons must equal the number of electrons in an atom for it to have no charge. Protons are positively charged particles, and electrons are negatively charged particles. A balanced number of protons and electrons results in an atom with a neutral overall charge.
How is an atoms atomic number related to it's number of protons to electrons?
The atomic number of an atom is the number of protons in the nucleus of that atom. The number of electrons will equal the number of protons in that atom if that atom is a neutral one. Other than that, we would have to know the atomic number (which is the number of protons that atom has), and the overall charge of the atom. With that information, we could discover how many electrons that atom had by simple mathematics. If an atom had 11 protons and a charge of +1, it would have one less electron than the number of protons, or 10 electrons. If an atom had 53 protons and a charge of -1, it would have 54 electrons. The ratio from atomic number to the number of protons in an atom is 1:1. The elements are categorized by the number of protons they have, as that is the difference between two elements. Conceptually, atomic number and proton number are the same.
What is the relationship between the atomic number and the electrons in neutral atom?
In a neutral atom the number of protons is equal to the number of electrons. And by definition the atomic number of an atom is equal to the number of protons in it. So the atomic number of a neutral atom is equal to the number of protons or the number of electrons in the atom.
What is the charge of a model atom element?
The charge of an atom is the difference between the number of protons and the number of electrons. Normally they balance, so the charge is 0. If there are extra electrons, the atom is an ion, and is considered negative. Conversely, an excess of electrons means positive.
