Zinc has ten 3d electrons.
Ten 3d electrons are in the atom of Zn.
the electrons and protons are always the same as the atomic #. so whatever the atomic # is, that's the answer. hope this helps :) source: studying for a cheemistry test that i have tomorrow :/
Yes, from atom number 21 (Sc) to 30 (Zn) are the 3d-transition-elements, group 3 to 12 in period IV of the periodic table.
Zn +2, Cl -1
the same as normal zinc it's just lost 2 electrons.
66 amu will be its mass
35 neutrons
2 electrons. The electron configuration of Zn is 2.8.18.2

Yes. Zn is a metal atom.
Yes, from atom number 21 (Sc) to 30 (Zn) are the 3d-transition-elements, group 3 to 12 in period IV of the periodic table.
The MnO2 would like to take electrons from the Zn much the same way that a bully would like to take someones lunch money. The problem for MnO2 is that it is not touching the Zn. The MnO2 is touching the graphite electrode and is trying to pull off the graphite electrons. Graphite is tougher than Zn and will not give up electrons but there is a tug. The graphite makes the positive electrode of the cell. On the Zn side, the Zn is the electrode and the electrons are not held very well by Zn. So the Zn electrode has pressure of electrons wanting to leave and the graphite electrode has suction that wants more electrons. The pressure difference can be measured as 1.5 volts. Volts are used to measure electrical pressure. When a light bulb or something is connected then electrons from the Zn electrode have a path to go to the graphite electrode. The graphite is willing to give electrons to MnO2 because it can get them back from the Zn through the circuit. Also when the Zn electrode loses 2 electrons a Zn atom turns into an ion and dissolves in the electrolyte. Because of its positive charge it is attracted to the correspondingly formed negative charge at the graphite when MnO2 took an electron.
Iron (Fe), 26 electrons in neutral atom, 23 in Fe3+. Rust, Fe203 has Fe3+ ions.
There are : 1 zinc atom 2 chlorine atoms 6 oxygen atoms in this zinc chlorate molecule.
One atom per molecule.
No, that electron configuration does not exist. After the 3p orbital fills with electrons, the next lowest energy orbital is 4s. After 4s contains 2 electrons, then 3d can accept electrons, upto 10. The element with this electron configuration is zinc, one of the transitional metals. Although 3d is full, those electrons can be 'valence' electrons and given to non-metals to form ions, such as Zn+2 or Zn+4. So 3d really acts like a 4th shell orbital and will still be quite reactive even when full. To see just how reactive these electrons are, look at the youtube videos embedded in this site: http://www.chemicool.com/elements/zinc.html.
