The atomic mass NUMBER equals the number of protons and neutrons in an atom. DO NOT confuse this with the mass of an atom.
tetrahederal
in the third shell, an electron has more energy and is further from the nucleus
The second electron shell of an atom can hold a maximum of 8 electrons.
Maximum of 32 electrons.
Iodine has 7 valence electrons. I- contains 8 valence electron.
The maximum number of electron shells in an atom is seven. Each shell can hold a certain number of electrons determined by the formula 2n^2, where n represents the shell number (1, 2, 3, ...).
the valence electron number equals the group number. the principal energy level equals the period number it's located in.
The number of protons in an atom's nucleus determines its position as an element on the periodic table. This number is known as the element's atomic number. Each element has a unique atomic number, which corresponds to its unique position on the periodic table.
The maximum number of orbits in an atom is seven. These orbits are known as energy levels or electron shells, and electrons can occupy up to seven of them based on their energy level and distance from the nucleus.
In an atom, the number of electrons with quantum number n equals 2 is determined by the formula 2n^2. For n = 2, the maximum number of electrons is 2(2)^2 = 8.
the no. of electron shells in an atom varies for every element in the periodic table, depending on its no. of electrons in the atom. the no. of shells of an atom of an element ca be derived through the period of the periodic table. elements in the 1st period has only 1 shell and so forth.
Scientists have designated electrons as having a negative charge and protons as having a positive charge. One positive proton can hold one negative electron in orbit. Thus, an atom with one proton in its nucleus normally will have one electron in orbit (and be labeled a hydrogen atom); an atom with ninety-four protons in its nucleus will normally have ninety-four electrons orbiting it (and be labeled a plutonium atom).
If you are asking about the number of electrons then it would be 8. The first shell can hold a maximum number of 2 electrons. The second and third shell would have a maximum of 8 electrons each.
You can determine how many valence electrons an atom has by what family the element of the atom is in. For instance, if the element is in family 8A, the number of valence electrons will be 8. Or, if the element is in family 2A, the number of valence electrons for the atom will be 2. So, whatever number family the atom is in, the number of valence electrons equals that.
