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.

Which isotope contains the greatest number of protons?
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
An atom of gold with 79 protons 79 electrons and 118 neutrons. What's the mass number?
Atomic mass is the number of protons plus the number of neutrons so, in the case of gold, the mass number = 79+118 which is 197
Definition of atomic number?
if u mean the atomic number of a chemical element it is the number of electrons and protons it has the other number is the number of neutrons e.g ununoctium number 118 is the atomic number the other number i think is 7
How many protons neutrons and electrons does ununseptium have?
protons 114 electrons 114 number of neutrons: atomic mass of an isotope - atomic number of the element; Uuq has many isotopes, each with a different number of neutrons.
How many boxes are there in the periodic table?
There are 118 elements known and hence there are 118 boxes in the modern periodic table. Each box represent a given element.
How many electrons are in an ununoctium?
118 protons and 118 electrons, as its atomic number is 118.
How many atoms does electrons have?
Atoms have 1 to 118 electrons. For a neutral atom the number of electrons is equal to the number of protons (atomic number).
What number represents the number of protons you an atom?
The atomic number. Look on the periodic table, the atomic numbers are the integers from 1 to 118.

How can you use the periodic table to find the amount of protons and electrons for an element?
The atomic number of an element is the number of protons in the nuclei of its atoms, and the elements are arranged according to their atomic numbers from 1 to 118. A neutral atom has the same number of electrons as protons.
What does a periodic table have?
a modern periodic table should have the 118 elements, their atomic numbers, and their masses. to find the number of protons and electrons, they are the same as the atomic number. to find the neutrons, subtract the protons from the mass.
How many protons neutrons and electrons does ununseptium have?
protons 114 electrons 114 number of neutrons: atomic mass of an isotope - atomic number of the element; Uuq has many isotopes, each with a different number of neutrons.

There are 118 elements known and hence there are 118 boxes in the modern periodic table. Each box represent a given element.
How many neutrons are in an atom of gold?
79 protons, 118 neutrons, atomic mass;197.967
An atom with 68 neutrons and 50 protons has a mass number of?
An element with 68-neutrons (n) and 50-protons (p) would have a mass number of 118-atomic mass units (amu). Amu equals the sum of the proton and neutron numbers for any element. In this case atomic number 50 also signifies that it is an atom of tin (Sn).
