Not necessarily. The atomic number is the same amount as the protons found in a certain element. remember that the number of protons are equal to the number of electrons as well.
EX - Calcium's atomic number is 20 so therefore there are 20 protons and 20 electrons in the element.
The atomic number also helps you find any valence electrons
EX- oxygen's atomic number is 8 so you have 2 electrons filling the 1st orbital and 6 filling the 2 orbital. but the 2nd orbital is supposed to have 8 electron so there are 6 valence electrons.

What are the atomic number of an element in a particle?
The number of protons in the nucleus of an atom determines an element's atomic number. In other words, each element has a unique number that identifies how many protons are in one atom of that element. For example, all hydrogen atoms, and only hydrogen atoms, contain one proton and have an atomic number of 1. All carbon atoms, and only carbon atoms, contain six protons and have an atomic number of 6. Oxygen atoms contain 8 protons and have an atomic number of 8. The atomic number of an element never changes, meaning that the number of protons in the nucleus of every atom in an element is always the same.
What is the atomic number of diamond?
Diamond does not technically have an atomic number as it is not an element. a diamond is a crystal made from many atoms of carbon which has an atomic number of 6.
Definition of atomic mass and atomic number?
the atomic number: The number of protons in the nucleus of an atom determines an element's atomic number. In other words, each element has a unique number that identifies how many protons are in one atom of that element. For example, all hydrogen atoms, and only hydrogen atoms, contain one proton and have an atomic number of 1. All carbon atoms, and only carbon atoms, contain six protons and have an atomic number of 6. Oxygen atoms contain 8 protons and have an atomic number of 8. The atomic number of an element never changes, meaning that the number of protons in the nucleus of every atom in an element is always the same. the atomic mass: it's the sum of neutrons and protons electrons in a single atom. to sum it up the atomic number is the number of protons and the mass number is the total number of every thing in an atom!
Does the atomic mass tell how many atoms are in an element?
The atomic mass tells how much amu one atom of an element weighs. It, minus the atomic number, rounded to the nearest one, gives you the number of neutrons in an atom. The atomic number is the number of electrons and protons. Protons have a positive charge, electrons have a negative charge, and neutrons are neutral.
Why aren't there many more than 100 occurring elements?
Because scientists just simply add a proton to an element, and they get the next element. For example, of you had one sodium atom (all sodium atoms have an atomic number of 11), and added a proton to it, you would get magnesium atom (all magnesium atoms have an atomic number of 12). So if scientists did this with element 99, they get element 100.
How many electrons are in an oxygen atom that hasan atomic number of 8?
The atomic number of an element _is_ the number of electrons in one of its atoms. Indeed, a sample of an element can be defined as any combination of atoms with the same atomic number. Oxygen is the element with atomic number 8. It is the element whose atoms have 8 electrons in their neutral state (and 8 protons).

How many atoms do there be in sulfur?
there are 16 atoms in sulfur, because the number of atoms in an element is equal to its atomic number, which is the number at the top of the square which is bolded
How many different types of atoms have atomic number 26?
Only one type of atom have atomic number 26, which is iron, Fe. The atomic number is unique to each element and is the number of protons in the atomic nuclei of that element. The number of protons identifies an element.
What determines the atomic number of a substance?
The atomic number is the number of protons in the nucleus of an atom, while the atomic mass is the total mass of the nucleus (both protons and neutrons)
How many atoms neutrons and protons are in a element with an atomic number of 8?
15.999 or 16.000
How many protons will you have if your atomic number is 118?
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.
How do you determine how many protons are in an element?
Experimentally, I'm not sure, but I know you can look at your periodic chart, the large number over the symbol of each element is teh number of protons in that element.
How many electrons do oxygen atoms have?
The electrons in an element is the same as the protons and the atomic number. 8
What on the periodic table of elements represents how many protons the atoms of each element have?
The atomic number.
What do whole numbers on the periodic table represent?
The whole number, the one at the top, above the element's symbol in the element box, is the atomic number. The atomic number is the number of protons per atom in that particular element. The bottom number, that is always a decimal, is the atomic mass.
