30 The atomic number is the number of protons
The mass number of an atom is the sum of its protons and neutrons. Copper has an atomic number of 29, which means it has 29 protons in its nucleus. If it has 36 neutrons, then its mass number would be 29 (protons) + 36 (neutrons) = 65.
A mass number is the sum of numbers of protons and neutrons in an atom. Therefore, an element with a mass number of 65 and 36 neutrons contains (65 - 36) or 29 protons and is therefore an atom of copper.
The atomic number of zinc (Zn) is 30. The atomic weight of Zn is 65.39 grams per mole. See the Web Links and the Related Questions to the left of this answer for a periodic table and more information about this element.
No, each atom does not have the same mass. The mass of an atom is determined by the number of protons, neutrons, and electrons it contains. Different elements have different numbers of these subatomic particles, resulting in variations in atomic mass.
30 The atomic number is the number of protons
The mass number of an atom is the sum of its protons and neutrons. Copper has an atomic number of 29, which means it has 29 protons in its nucleus. If it has 36 neutrons, then its mass number would be 29 (protons) + 36 (neutrons) = 65.
An atom of copper-65 has 35 neutrons in its nucleus. This is calculated by subtracting the atomic number (which is 29 for copper) from the mass number (which is 65 for copper-65), as neutrons and protons together make up the mass number.
AnswerThere are 30 electrons, 25 neutrons, 30 protons,the atomic number is 30 and the atomic mass is about 65.
An atom with a mass number of 65 and 35 neutrons would have 30 protons. This is because the mass number is the total number of protons and neutrons in the nucleus, and the number of neutrons is subtracted from this to find the number of protons.
36 The answer of this question is there are 30 protons and 35 neutrons
All tin isotopes have 50 protons. For neutral atoms, the number of electrons will also be 50. The neutron number is 119 - 50, which is 69.
A mass number is the sum of numbers of protons and neutrons in an atom. Therefore, an element with a mass number of 65 and 36 neutrons contains (65 - 36) or 29 protons and is therefore an atom of copper.
Cadmium has an atomic number of 48, therefore it has 48 protons in the nucleus and 48 electrons in the neutral atom. There are a number of isotopes (list from wikipedia article Cadmium) 106Cd 58 neutrons 108Cd 60 neutrons 111Cd 63 neutrons 112Cd 64 neutrons 113Cd 65 neutrons 114Cd 66 neutrons 116Cd 68 neutrons
Cu 65 has the same number of protons as any other copper, which is 29. It also has 29 electrons since the charge is neutral. The number 65 only changes the number of neutrons, which in this case would be 36.
Protons- 30 Electrons- 30 Neutrons- 35 Zn-65 means the atomic number plus the number of neutrons equals 65. Zinc always has 30 protons; therefore, it's atomic number is 30 and it has 30 protons and electrons. The remaining number is the neutrons: 65-30= 35
Being Cu-64 says it is copper. Copper has 29 protons in the nucleus. Since there are the same number of electrons as protons it must have 29 electrons. The number 64 indicates there are 64 particles in the nucleus. Sine 29 are protons, the rest must be neutrons so there must be 35 of these.
