The element is gold (Au). The atomic number (79) tells us the number of protons in the nucleus, which is equal to the number of electrons in a neutral atom. The Atomic Mass (179) is the sum of the protons and neutrons in the nucleus.
The atomic number of Br 79 is 35, as it is the number of protons in the nucleus. The atomic mass of Br 79 is approximately 79, as it is the sum of protons and neutrons in the nucleus.
The atomic number of gold (Au) is 79.The atomic weight of gold is 196.9665 grams per mole.Gold has 79 protons, 118 neutrons and 79 electrons.See the Web Links and the Related Questions to the left of this answer for a periodic table and more information about this element.Gold is a very rare element. Atomic number of it is 79.Gold is a d block element. atomic number of gold is 79.
59 = # of protons and # of electons 59 protons make up 59 of the mass number (electons have an insignificant mass), so the rest of the mass must be from neutrons: 96 - 59 = 37 neutrons
Gold's mass number is 197. This indicates the total number of protons and neutrons in the nucleus of a gold atom.
gold is a metal element. atomic number of it is 79.
The atomic number of Br 79 is 35, as it is the number of protons in the nucleus. The atomic mass of Br 79 is approximately 79, as it is the sum of protons and neutrons in the nucleus.
mass number is simply the addition of the proton number and neutron number. we also know that proton number of the element is similar to atomic number. we also know that 79 + (197-79) is the no. of neutron no. of the gold. hence when atomic no. of the gold is 79 its atomic mass or mass number is 197.

An atom of selenium with an atomic number of 34 has 34 electrons. The mass number of 79 suggests that the total number of protons and neutrons in the nucleus is 79. Since the atomic number (protons) is given as 34, the number of neutrons can be calculated as 79 - 34 = 45.
The radioactive isotope 198Au has the mass number 198.
79; the mass number is the sum of the protons and neutrons, and the atomic number is the number of protons. So if you take the mass number (protons + neutrons) minus the atomic number (protons), you get the number of neutrons.
An atom with an atomic number of 79 has 79 protons in its nucleus. Since the atomic number represents the number of protons, this atom also has 79 electrons. The mass number (197) represents the sum of protons and neutrons, so subtracting the number of protons (79) gives the number of neutrons: 197 - 79 = 118 neutrons.
The only stable, and only naturally-occurring isotope of gold has mass number of 197. This is the number of protons and neutrons in each nucleus. Gold's atomic number is 79. This is the number of protons found in each gold atom. This determines its place in the periodic table, and its chemical properties: it is the defining property of gold. A nucleus with a different number of neutrons and the same 79 protons would be a different isotope with a different mass number; a nucleus with a different number of protons would not be gold, but some other element.
59 = # of protons and # of electons 59 protons make up 59 of the mass number (electons have an insignificant mass), so the rest of the mass must be from neutrons: 96 - 59 = 37 neutrons
For gold-197, there are 79 protons (equal to the atomic number), 79 electrons (since atoms are electrically neutral), and 118 neutrons (subtracted from the mass number - atomic number = 197 - 79 = 118).
The number of protons in an atom of any atomic number is the same as the atomic number, because that is the definition of atomic number. Therefore, in the given question, the answer is 34; the mass number is not needed to answer.
The mass number of an atom is the sum of its protons and neutrons. Since bromine (Br) has 35 protons, the mass number of Br-79 is 79 (35 protons + 44 neutrons).
