How many protons neutrons and electrons are in CU?

Copper has an atomic number of 29, so it contains 29 protons and 29 electrons. The atomic weight (sometimes called atomic mass) of an atom is approximated by the sum of the number of protons and the number of neutrons in the nucleus of the atom.

Just so, how many protons are in CU?


How many electrons protons and neutrons are there in an atom of copper 63?

EXAMPLE: Copper has an atomic number of 29. Its two main isotopes have mass numbers of 63 and 65. How many neutrons does each of the isotopes have? The 63Cu isotope has 63 – 29 = 34 neutrons.

How many valence electrons are in CU?

In addition, it has more than one oxidation state. Like many of the transition elements, copper has a colored ion. Copper typically forms a bluish green solution. Copper (Cu) has two valences Cu I (cuprous) has one valence electron and Cu II (cupric) has two valence electrons.
