What is the element? A. Protons/Electrons is 82 and neutrons is 110. B. Neutrons is 36 and Atomic Number is 29 and it has a charge of +1.
The number of protons is the same as the atomic number and the sum total of protons and neutrons is the atomic mass of an element.
A. Protons: 82 and neutrons: 110
Thus, atomic number is 82 and mass is 110 + 82 = 192.
Lead has an atomic number of 82 and a mass of 207.
The given element is an isotope of lead. In fact, it is one of the unstable isotopes of lead with a half life of 3.5 minutes. In comparison stable isotopes of lead such as those with atomic mass of 204, 206, 207 and 208 are very stable.
B. Atomic Number = 29, Neutrons = 36, Charge = +1
Atomic mass = 29 + 36 = 65
Copper has an atomic number of 29 and atomic mass of 63.
The given element is an isotope of copper with an atomic mass of 65.
