this elemnt has an atomic number that is double the atomic number of silicon?
Atomic number 27 : Cobalt Atomic number 28 : Nickel Atomic number 29 : Copper Atomic number 30 : Zinc Atomic number 31 : Gallium
You subtract the atomic number from the mass number.
The atomic number is equal to the protons and electrons of an element.
Number of neutrons = Mass number - atomic number
Negative 3.
The number of protons in a atom is equivalent to its atomic number. Hydrogen's atomic number is 1, there fore it has 1 proton. Coppers atomic number is 29 so it has a proton count of 29. And so on.
coppers mass is 64 29protons+35neutrons=64
Yes, an atom of copper contains electrons. copper is a neutral atom, thus the number of protons will equal the number of electrons. coppers atomic number is 29, thus there are 29 electrons and 29 protons in a copper atom.
Group 9
coppers formula is just >Cu<
what is coppers chemical family
coppers state of matter is solid.
the answer is that it is called a atomic number.
The atomic number is equal to the number of the protons in the atomic nucleus.
Atomic weight in atomic mass units = the number of protons + the number of neutrons. The number of protons is your atomic number. Subtract that from the atomic weight for the number of neutrons.
