Question

Copper has two stable isotopes, Cu and electrons in Copper-65? Cu. How many protons, neutrons and 29 protons, 34 neutrons and 29 electrons 65 protons, 29 neutrons and 65 electrons 29 protons, 36 neutrons and 29 electrons 36 protons, 29 neutrons and 36 electrons

Answer 1

65 B In Copper cu isotope, 29 Protons = 29. neutrons = (mon Moss no Pacton no (65-29) = 36 electrons = 29 11 8 The false about electrons and the energy levels they occupy in the structure of an atom in when the electrons are acquired or donated by an individual atom, the identity of the atóm changes. The other 3 statements are correct Chemist has interest to 1A-8A fo the main group elements because :- The group number Reveals the number of valance electrons for all the elements in that group. unreactive 8 The noble gosses reffered to as inest or Chemically → Their outermost ene energy levels already full of electrons and therefore did not participate participate in the transfer Sharing of electrons with other elements. are they Q2
