When you talk about an isotope, the number that follows the element name is the number of neutrons. So, 27 neutrons. Every cobalt has 27 protons. If the number of protons were to change (which doesn't happen naturally), then it would no longer be cobalt. Having the same number of protons as neutrons, however, would not make this an isotope. What you are talking about is normal cobalt.
Chlorine, atomic number 17, has 17 protons. So an uncharged atom has 17 electrons.But when Chlorine takes on 1 electron, which often happens in ionic bonds, it has 18 electrons, which fills the outer shell of electrons.
In the Periodic Table aluminium is described as [27/13]Al 27 is the atomic mass ; the total of all the neutrons protons (nucleons) 13 is the atomic number ; the total of all the protons in the nucleus. Hencethe total neutrons is the mass subtracted from the number. 27 - 13 = 14 is the total number of neutrons in aluminium.
The symbol Mn indicates a manganese atom, which always has 25 protons. The electroneutrality required for any atom requires the presence of 25 electrons to balance the electrical charge of the 25 protons. The mass number, 52 in this instances, is the sum of the numbers of protons and neutrons. Therefore, the number of neutrons in the isotope is 52 - 25 or 27.
All parts of the atom weigh something but when doing calculations electrons are said to have a mass of 0. This is because they actually have a mass of 1/1836 amu which is insignificantly small and so it is disregarded.
Mass number = proton number + neutron number SO, Mass number(Aluminium) = 13+ 14 =27
The neutral atom has 27 electrons.
In a cobalt atom, there are 27 electrons. This number is found by looking at the atomic number of cobalt on the periodic table, which is 27. Electrons are equal in number to the protons in a neutral atom.
The cobalt neutral atom (57Co) contain 25 protons, 25 electrons and 32 neutrons.
Yes, the atom will be electrically neutral. This is because the number of protons (positive charge) is equal to the number of electrons (negative charge), balancing out the overall charge of the atom.
The neutral atom of cobalt has 27 electrons. The number can vary up or down depending on the chemistry of the sample of cobalt. A link is provided to the Wikipedia article on the element cobalt.
Cobalt, with atomic number 27, has 27 protons and 27 electrons in a neutral atom. The number of neutrons in cobalt can vary depending on the isotope. The most common isotope, cobalt-59, has 32 neutrons.
A cobalt atom with have 27 electrons regardless of the isotope.
If the atom of Cobalt is neutral, it's amount of electrons will be the same as the number of protons. The number of protons in the atom is the same as the mass number (the number you see on the Periodic Table). However, if it is not a neutral atom, there could be an infinite amount of possibilities. The above answer is true in that the number of electrons of an element will normally equal the number of protons. However, it is the atomic number, not the mass number, that tells you the number of protons (and, therefore, electrons) in a single atom of an element. The atomic number of Cobalt is 27, therefore 27 protons, 27 electrons. Its average atomic weight is 58.9 which is the combined weight of its protons and neutrons - all other sub-atomic particles such as electrons are presumed to weigh nothing, or nearly so. Cobalt has many isotopes, of which Co58 is one, but each will have the same number of protons and electrons. They will differ in atomic weight due to a difference in the number of neutrons.
The mass number is 59; this element s cobalt.
Cobalt-60 has 27 protons, (Cobalt has an atomic number of 27) 33 neutrons (mass number less atomic number) 27 electrons in the neutral atom (balancing the charge of the 27 protons)
In a cadmium atom, all 27 s orbitals are filled with electrons. Cadmium has 48 electrons, and the s sublevel can hold a total of 2 electrons per orbital, so 27 orbitals are needed to accommodate all the electrons.
The mass number of an atom is the sum of its protons and neutrons. In this case, the atom has 27 protons and 33 neutrons, so the mass number would be 27 + 33 = 60.
