Only the atomic radius is equivalent - 128 pm.
Cu
The atomic mass of Cu (Copper) is 63.546 amu (atomic mass unit).
Copper is a metal element. Atomic mass of it is 64.
Copper is a meta element. Atomic mass of it is 64.
Ni atomic number 28, between Co and Cu
The atomic mass of Cu is: 63.546 g.mol The atomic mass of Cl2 is: 35.453 g.mol So your answer would be: Cu has the largest Atomic mass.
Cu
The atomic mass of Cu (Copper) is 63.546 amu (atomic mass unit).
Copper (Cu) and Silver (Ag) are in the same group, and so would be expected to have the same number of valence electrons, and behave similarly in a chemical reaction. Ag is in a higher period, and so has its valence electrons further away from the nucleus, and so has a greater atomic radius than Cu, and also weighs more than Cu. They are both transition metals.
the atomic symbol of copper is Cu.
The answer is: CU
Copper is a meta element. Atomic number of it is 29.
Copper is a metal element. Atomic mass of it is 64.
Multiply 564 grams of copper by 1 mole over the atomic mass of copper (represented in grams). 564 g Cu * 1 mol Cu / (atomic mass) g Cu The atomic mass is located on the periodic table and represented in atomic units. The same value is used here, but with the unit as grams.
Copper is a meta element. Atomic mass of it is 64.
Ni atomic number 28, between Co and Cu
