What is a atomic number in a element?
The atomic number of an element refers to the number of protons in the nucleus of the atom of that element, and is unique to each element. The atomic weight is the weight of an atom of the element compared with the weight of a single proton, and consists of number of protons and neutrons in the nucleus of the atom of that element, and different atoms of the same element can have different numbers of neutrons, and therefore more than one atomic weight: it is usually given as an average. the atomic number on an element is simply the number of protons and electrons in the element. however, it is not the total number of them.
Can neon have more than one element?
No, neon is a chemical element on its own with the symbol Ne and atomic number 10. It is a noble gas that exists as a single element in the periodic table.

What is the difference between atomic size and atomic number?
The atomic number of an element determines the number of protons that are present in that element. The atomic size refers to the distance that the outermost valence electrons are from the nucleus.
What element has one more proton then argon?
The element with one more proton than argon is potassium, which has atomic number 19. Argon has an atomic number of 18.
Can the atomic number of an particular element ever change?
No, the atomic number of an element can't change. Because, we can identify an element by its atomic number and atomic mass. and hence they have been arranged in the periodic table on the basis of their mass number and atomic mass so , it couldn't be changed. Every element has a fixed atomic number..
What is the atomic number and atomic mass of this element?
Atomic number is the number of protons. Atomic mass is (mostly) the sum of the masses of the protons and neutrons (more or less).
What is the atomic number of Carbon?
The atomic number of carbon (C) is 6.The atomic weight of C is 12.011 grams per mole.The atomic number of an element is the number of protons in the element. Carbon has 6 protons and therefore has an atomic number of 6(See the Related Links below this answer for a periodic table with more information about this element)
