If the atomic number is 118, the number of protons is 118. Atomic number is the number of protons in the nucleus of an atom. The elements are arranged in increasing order of atomic number. All of the atoms of an individual element have the same atomic number. Atomic number identifies an element.
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).
Au-197 has 79 protons, 79 electrons, and 118 neutrons. The atomic number of gold (Au) is 79, indicating the number of protons. The isotope Au-197 specifies the atomic mass, which is the sum of protons and neutrons. So, subtracting the atomic number from the atomic mass gives the number of neutrons.
Gold, with the atomic number 79, has 79 protons in its nucleus. In a neutral atom, the number of electrons is equal to the number of protons, so gold also has 79 electrons. The number of neutrons can be calculated by subtracting the atomic number from the atomic mass of gold, which is typically around 197. This gives gold approximately 118 neutrons.
Gold 198 has 118 neutrons. This is determined by subtracting the atomic number (number of protons) from the atomic mass number (sum of protons and neutrons). In the case of gold, the atomic number is 79, so 198 - 79 = 119 neutrons.
Atomic number is a measure of protons and electrons. extra or less Neutrons are what make an isotope and are not included in atomic number. therefore element with the highest atomic number will also be the isotope with the highest atomic number. on my periodic table it is lawrencium at 103. (note although this might have extra neutrons making it an isotope, it will always have the same atomic number - atomic number isn't what determines an isotope it is mass number) if you meant mass number (which is what determines an isotope), you can subtract the atomic number from the mass number to find out how many neutrons there are and determine whether it is an isotope or not
118 protons and 118 electrons, as its atomic number is 118.
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).
Au-197 has 79 protons, 79 electrons, and 118 neutrons. The atomic number of gold (Au) is 79, indicating the number of protons. The isotope Au-197 specifies the atomic mass, which is the sum of protons and neutrons. So, subtracting the atomic number from the atomic mass gives the number of neutrons.
Gold, with the atomic number 79, has 79 protons in its nucleus. In a neutral atom, the number of electrons is equal to the number of protons, so gold also has 79 electrons. The number of neutrons can be calculated by subtracting the atomic number from the atomic mass of gold, which is typically around 197. This gives gold approximately 118 neutrons.
Atoms have 1 to 118 electrons. For a neutral atom the number of electrons is equal to the number of protons (atomic number).
The atomic number. Look on the periodic table, the atomic numbers are the integers from 1 to 118.
Gold 198 has 118 neutrons. This is determined by subtracting the atomic number (number of protons) from the atomic mass number (sum of protons and neutrons). In the case of gold, the atomic number is 79, so 198 - 79 = 119 neutrons.

An Osimum atom with mass number 188 has 118 protons (atomic number for Osmium). To find the number of neutrons, we subtract the atomic number from the mass number: 188 - 118 = 70 neutrons.
For gold (Au), atomic number = 79, so it has 79 protons and 79 electrons. The number of neutrons can vary depending on the isotope of gold, but a common isotope, Au-197, has 118 neutrons.
The mass number is the sum of protons and neutrons in the nucleus of an atom. In this case, an atom of gold with 79 protons and 118 neutrons would have a mass number of 197 (79 protons + 118 neutrons = 197 mass number).
Platinum is a metal element. atomic number of it is 78.
