Definition of cobalt - the chemical element of atomic number 27, a hard silvery-white magnetic metal definition of cobalt - the chemical element of atomic number 27, a hard silvery-white magnetic metal dictionary as he tilted his head back and looked up at the star-dusted cobalt sky’ ‘the softly tailored look is also very much in. Isotope of an element is defined by the sum of the number of protons and neutrons in its nucleus elements have more than one isotope with varying numbers of neutrons for example, there are two common isotopes of carbon, 12 c and 13 c which have 6 and 7 neutrons respectively.
The number of protons determines the element, but the number of neutrons in the atom of any one element can vary each variation is an isotope ten radioactive isotopes of cobalt are known also.

Cobalt is a chemical element with symbol co and atomic number 27 like nickel, cobalt in the earth's crust is found only in chemically combined form, save for. For example, the element cobalt (co) has an atomic number of 27 this atomic number is also the number of protons in the atom this atomic number is also the number of protons in the atom therefore, co has 27 protons. Cobalt you can use the periodic table to find answers to questions like this its super easy- protons are the same as the atomic number, so whatever the atomic number is of the element on the. The number of protons determines the element, but the number of cobalt's use in magnetic alloys is critical for devices that must hold a magnetic field, such as electric motors neutrons in the atom of any one element can vary.
Based upon that oxidation number, an electronic configuration is also given but note that for more exotic compounds you should view this as a guide only in compounds of cobalt (where known), the most common oxidation numbers of cobalt are: 3, and 2.
