  that's way wrong its 27 protons and electrons and 32 neutrons

9 valence electrons

  DOES ANYONE KNOW THE NUMBER OF ELECTRONS IN COBALT FOR MY SON'S PROJECT?

27 electrons, 9 valence electrons if you want to know.

  I just know that it was first discovered in Sweden in 1735-39

George Brandt discovered Cobalt in Sweden in 1735

  what is cobalt wanted for?

Cobalt has many uses for its compounds. First, it has been used for distinctive and attractive color to glass objects. Blue is the most well known shade, but pink and green are also present in glass coloring. The element is also a powerful gamma ray emitter used for radio therapy, leak detection in pipes, and irradiating food to kill bacteria. A gamma ray is a high energy electromagnetic radiation given off by some nuclei. Only some food-processing plants use radiation from Co 60 to kill bacteria in foods. Cobalt Is a very useful radioactive isotope. Cobalt can make various alloys with other metals. When mixed with Iron, Cobalt can produce high temperature steel. With Aluminum and Nickel, it is used in magnets. Carbon and Tungsten, or Chromium and Iron, mixed with Cobalt can formulate hard alloys for drill bits and cutting tools. With those same elements, Cobalt can withstand high temperatures used in gas turbines and jet engines. It is also used in cobalt magnets, MRI machines, electronic devices, and speakers with Aluminum, Nickel, and Iron. Cobalt occurs in the minerals Cobaltite, Smaltite, and Erythirite and is associated with Nickel, Silver, Lead, Copper, and Iron ores. Some other uses include; dental and surgical applications, Catalysts, and Cobalt boats. Catalysts are substances that increase the speed of chemical reaction without being consumed by the reaction. Cobalt is also present in meteorites.

  when was the elemnet of cobalt invented

It wasnt invented but it was discovered in 1735 by george brant in stockholm swedan, but it was named after German miners. Kobald= goblin in german.

  I am doing a science project and I was wondering how many prontons cobalt has, how many electrons cobalt has, and how many neutrions cobalt has.

27 protons
