The atomic number is a measure of the number of protons in an atom's nucleus. It determines the element's identity on the Periodic Table.
What else can I help you with?
What is the atomic number measure of?
Is equal to the number of electrons
If there is a difference between a substance's atomic number and its atomic mass and which measure must be the larger number?
The atomic number represents the number of protons in an atom, while the atomic mass represents the sum of protons and neutrons. Generally, the atomic mass is larger than the atomic number for most elements since it includes both protons and neutrons.
What is the relationship of atomic size and atomic number of elements?
R = r0A1/3 Where R is nuclear radius (I'm assuming this is your chosen measure of size), r0 is the constant 1.05fm and A is the nucleon number, or mass number.
What is the atomic number of F plus the atomic number of Na?
The atomic number of fluorine is 9.The atomic number of sodium is 11.
What is an example of Atomic Number?
Atomic number= number of protons. Hydrogen atomic number=1
What is the atomic number measure of?
Is equal to the number of electrons
If there is a difference between a substance atomic number and its atomic mass which measure must be the larger number?
The atomic mass number must be higher as that represent the number of protons and neutrons in an element. Whereas only the number of protons are represented in the Atomic Number.
What unit of measure would be use to measure the mass of a proton?
You Use Atomic Mass Number
If there is a difference between a substance's atomic number and its atomic mass and which measure must be the larger number?
The atomic number represents the number of protons in an atom, while the atomic mass represents the sum of protons and neutrons. Generally, the atomic mass is larger than the atomic number for most elements since it includes both protons and neutrons.
When does atomic number occur?
It doesn't occur its just the way an way they measure atoms in an element
What is the relationship of atomic size and atomic number of elements?
R = r0A1/3 Where R is nuclear radius (I'm assuming this is your chosen measure of size), r0 is the constant 1.05fm and A is the nucleon number, or mass number.
This element has an atomic number that is double the atomic number of silicon?
this elemnt has an atomic number that is double the atomic number of silicon?
How can you find number of neutrons in an atom when the mass number is not given?
You cannot, just by looking. The mass number is the number is the number of protons PLUS the number of neutrons -- but if you are not given the mass number, you have little to begin with except to look up the number of neutrons yourself. ---------------------------------------------------------------------- The other way to do it would be to measure the number of protons and neutrons in the laboratory. --------------------------------------------------------------------- Isn't it amazing about these people who say "there is no way of knowing" (as this answer formerly said), when the real answer is YOU CAN GO MEASURE IT ! That is the real way to find out nearly anything in chemistry and physics. D.A.W.
What units do you use to measure atomic mass?
A mole (mol). You can convert to kilograms using Avagadros number.
What is the number of protons in the neucleus called?
the answer is that it is called a atomic number.
Atomic number in the atomic nucleus?
The atomic number is equal to the number of the protons in the atomic nucleus.
This element has the atomic number that is double the atomic number of silicon?
The element with an atomic number that is double the atomic number of silicon is germanium, with an atomic number of 32. Silicon has an atomic number of 14.
