How do you know how many electrons are in an atom?
Except for ions, the number of electrons in an atom are equal to the number of protons. The atomic number will tell you the number of protons, and consequently the number of electrons in an electrically neutral atom. In the case of an ion, adjust the number by the indicated charge; for example Na+1 will have 11 (the atomic number of Na) - 1 (since electrons have a negative charge, you subtract the charge) = 10 electrons.
How do you find electrons in elements on the periodic table?
The number of electrons are equal to the number of protons which is equal to the atomic number. That's if you're trying to find the number of total electrons. If you want to find the number of valence electrons (electrons in the outermost shell) you must look at the group numbers. The group number is equivalent to the number of valence electrons.
The number of protons in one atom of an element determines the atom's what?
Electrovalent bonds
What is a a atomic number?
The atomic number of an atom is the atoms number of protons. The number of protons is same as the number of electrons. on a Periodic Table it is usually on top of the elemental abbreviation
What electric charge is in atoms with equal numbers of electrons and protons?
A proton and an electron possess equal amount of charge (about 1.6e-19 C), except that a proton carries a positive charge and an electron, negative. Hence, the net charge is nil -- the atom is electrically neutral.
Neutral atoms of neon atomic number of 10 have the same number of electrons as each what except?
Argon, it ha 18 electrons.
Is atomic mass number of protons or number of electrons if a neutral atom?
Neither, except for the anomalous hydrogen-1 isotope. The atomic mass number of an atom is the sum of the numbers of protons and neutrons in the atom. If the questioner meant "atomic number" instead of "atomic mass number", the atomic number is fundamentally the number of protons, but if the atoms is neutral, the numbers of protons and electrons are the same.
What indicates the number of an electron in a neutral atom?
Always the Atomic Number = Number of Protons If electrically neutral, Atomic Number = Number of Electrons = Number of Protons

How do you fnd electrons on the periodic table?
Often by the atomic number except for ions.
An atom is electrically neutral because?
An atom has no electrical charge because the negative charge of the electrons counteract the positive charge of the protons and the neutrons in the nucleus have a neutral charge. For example, Carbon has 6 electrons(-6 charge) and has 6 protons(+6 charge). Giving it an atomic weight of 12 and a charge of 0. The 6 neutrons do not change this charge, they keep it the same because they are neutral. (:
How many protons are there in a neutral atom with thirteen electrons?
13. Both have same charge except electron has negative and proton positive. Neutrons are electrically neutral

How do you infer that an atom is electrically neutral or an ion by referring to its number of electrons?
if number of electron and protons are equal(except for H,as it has no proton,so it shoulh has one electron to be electrically neutral).
The number of protons in one atom of an element determines the atom's what?
Electrovalent bonds
Atoms are made of what subatomic particles?
All atoms, except Hydrogen-1 which is only one electron and one proton, are made of three fundamental particles: neutrons, protons, and electrons. Neutrons and protons are also made of up and down quarks. Electrons have very little mass and a charge of negative one while protons and neutrons are more massive and of approximately equal mass. Neutrons have no charge (neutral charge) whereas protons have a charge of positive one.
What is the number of protons plus the number of electrons?
The number of protons plus the number of electrons isn't a recognized figure in chemistry. The number of protons is the atomic number of an element. The number of electrons is the same as the number of protons except when the element is an ion. An ionic compound results in one or more electrons moving from one element to another element. Although this is a simplification, it can be described as the atom gaining or losing electrons. The number of protons plus the number of neutrons is the atomic weight of an element.
