It is constant for elements. IT depends on number of protons that atom has.

Each element has its own characteristic atom in which a. the atomic weight is constant b. the atomic number is constant c. the mass number is constant?

b. the atomic number is constant. The mass number is not constant because there are isotopes of an element that have the same number of protons but different number of neutrons. Likewise, there are isotopes of the same element with different atomic weights.


What changes in atomic number and mass number occur in beta emission?

Electron (beta minus) decay: the atomic mass remain approx. constant, the atomic number will be greater with 1 Positron (beta plus) and electron capture decay: the atomic mass remain approx. constant, the atomic number decrease with 1 Double beta decay: the atomic mass remain approx. constant, the atomic number will be greater with 2


Do all atoms of argon have the same atomic number?

Yes, all atoms of argon have the same atomic number, which is 18. Atomic number refers to the number of protons in the nucleus of an atom, and for argon, it always remains constant at 18.


Do all of atoms of argon have same atomic number?

Yes


Identical atomic number but different mass?

I'm assuming you ask about the situation when isotopes has the same atomic number but different masses; this is normal because the number of neutrons in the isotopes of the same element is variable. But the number of protons (identical to atomic number) remain constant.


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.


Why is atomic mass not a constant number?

The atomic mass is the average of all of the different isotopes of the element present in the sample. Samles taken from aound the worlld for some elements have slightly different isotope ratios and therefore have different atomic masses.


Does the atomic number of the element change when its atom forms ion?

No. Atomic Number is defined as the number of positive protons, and when a ion is formed(irrespective of cation or anion) only negative electrons will be lost or added hence the proton number is constant.

What number remains constant in every atom of an element?

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 electronsWhen 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


What does atomic number represent?

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
