8 electrons which equals the atomic number
Which particle in atom dose not contain oxygen?
An atomic nucleus contain protons, neutrons and electrons - not oxygen.
What dose the atomic number tells you?
The Atomic Number tells us the position of the element in the Periodic Table. It also tells us the number of protons and electrons in an atom of that element. The Atomic Mass/Weight is different. The Atomic Mass is the total numbers of nucleons ( protons and neutrons) in the nucleus of an atom. For a given element the atomic mass can vary. This is because the nucleus may have a different number of neutrons. These different masses of a given element are named 'Isotopes'.
What dose the atomic number of an element represent?
The atomic number of an element represents the number of protons in the nucleus of an atom of that element. It is a unique identifying characteristic of an element because different elements have a unique number of protons in their nuclei.
How many electrons dose a chlorine atom have?
The chlorine atom has 17 protons and electrons.
How many protons dose a atom have?
The number of protons in an atom is different for every element. If you look at the periodic table, then the number labeled "atomic number" is the number of protons.
How many electrons dose Mn plus 2 have?
Mn2+ has 25 electrons. Mn2+ means that the manganese atom has lost two electrons, resulting in a +2 charge. Mn is the symbol for manganese, which has an atomic number of 25, indicating that it normally has 25 electrons in its neutral state.
How many protons dose calcium have?
A calcium atom (Ca) has 20 protons.Another way of saying this is: the atomic number of calcium is 20.
How many electrons dose Ni2- have?
Nickel is a metal element. There are 28 electrons in a single atom.
What dose the atomic number tell us?
the # of protons
How many protons electrons and neutrons dose francium contain?
Francium has 87 protons and electrons; the number of neutrons is different for each isotope and francium has ca. 40 isotopes ad isomers. Number of neutrons = Atomic mass of the isotope - 87
What dose Fe has 26 protons how many neutrons or electrons dose it have?
Iron has 26 electrons; the number of neutrons is different for each isotope (number of neutrons = mass number - 26).
