An element will always have the same number of protons. The atomic number(Z) is the number of protons. For example, if you told that an element has 8 protons, all you have to do is look at the Periodic Table for the element that has atomic number 8. In this case it would be Oxygen, with symbol (O).
However, they might have different number of electrons and neutrons.
When they have an electric charge they are called ions. You can calculate the ion charge with this formula:
Ion charge = # of protons - # of electrons
When they have different number of neutrons they are called isotopes. You can calculate the mass number(A) with this formula:
Mass number(A): #of protons + # of neutrons
Every element has a specific number of protons, which is how an element is identified. That gives its atomic number. The number of neutrons can vary, and therefore is not useful in identifying an element.
Every element has its own kind of atom, identifiable from atoms of another element by its number of protons.
It is the number of protons in the nucleus of the atom and it determinnes many properties of the atom. The atomic number is also the number of electrons and is a constant for every element
Yes. Every element has a different number of protons.
Usually on the very top of every element.
Atomic mass increases with the ordered placement of the element of the periodic table. Conveniently, the number of protons, nuetrons and electrons also increase with numbered order on the table. Every element is assigned a number. This number is equal to the number of protons, nuetrons and electrons. I believe it's the nuetrons that make up the mass of the element, but not sure!
Each element has a different number of electrons. All atoms of that element have the same number of electrons. The number of electrons is the same as the number of protons.
True. The number of atoms in a mole of an element is determined by Avogadro's number, which is a constant (6.022 x 10^23) regardless of the element being considered. Each element's molar mass in grams is equal to one mole of that element's atoms.
The atomic number, or number of protons

The atomic number of an element is the number of protons in the nuclei of its atoms. Each element has a unique atomic number.
For every element, the number of protons, electrons, and atomic number are the same.
true
In a series circuit, the current through each element is the same current. Because the total current must flow through every element. In a parallel circuit, the voltage across each element is the same voltage. Because every element is connected individually across the power supply.
