Reference the atomic number of the atom on the Periodic Table. The electron count is generally equal to the number of protons
To calculate the number of valence electrons in an atom, you look at the group number of the element on the periodic table. The group number tells you how many valence electrons the atom has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
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.
Look up the atomic number of the element. The atomic number is the number of protons, in a neutral atom this is the same as the number of electrons.
the Atomic Mass number is the number of protons/electrons in an atom
the Atomic Mass number is the number of protons/electrons in an atom
The net charge of an atom or ion is determined by the balance of protons and electrons. Protons, which have a positive charge, and electrons, which have a negative charge, contribute to the overall charge of the atom. To calculate the net charge, subtract the number of electrons from the number of protons: ( \text{Net Charge} = \text{Protons} - \text{Electrons} ). If an atom has more protons than electrons, it is positively charged (cation), while more electrons than protons result in a negative charge (anion).
calculate the current due to revolution of electron in the outermost orbit of the Na atom, if the time period of revolution of electron is 2 micro second
the atomic mass number is the number of protons/electrons in an atom
First shell contains atmost two electrons. The formula is 2n. where n is the no. of shell u want to calculate its capacity of no of electrons..thanku
To calculate the mass of an atom, you can add up the masses of its protons, neutrons, and electrons. Protons and neutrons have a mass of about 1 atomic mass unit each, while electrons have a much smaller mass that can usually be ignored. The total mass of an atom is usually given in atomic mass units (amu).
A nitrogen atom has seven electrons.
For each element, the number of protons it has is equal to the number of electrons it has. However, if the atom has a different amount of electrons, then the charge will tell you that. If the charge is negative (-) then that says how many electrons the atom has gained, and if the charge is positive (+) then that says how many electrons the atom has lost.
