Bexause its similar with the Atomic Mass
What else can I help you with?
Why is the atomic mass of an element not a whole number while the atomic number is?
The atomic number refers to the number of protons in the atom. Since the proton cannot be an in-between number, the atomic number will have to be a whole number. On the other hand, the atomic mass does not have to be a whole number because it is the mass of an atom and is roughly equivalent to the number of protons plus the average number of neutrons in that particular element.
What is the difference between Mass number and Relative of atomic mass?
Atomic mass is the average of the masses of the naturally existing (i.e. mixture of) isotopes of one specific element.The atomic mass number is the sum of the protons and neutrons in the nucleus of an atom (specific for one specific isotope).
What is the nearest whole number of atomic mass of potassium?
The nearest Whole number of atomic mass of potassium is 69
Atomic mass differnet from the atomic mass number why is that?
The atomic mass is an average, allowing for the relative abundances of different isotopes.
What is the Relative atomic mass of chromium?
Chromium is a meta element. Atomic mass of it is 52.
Why is the relative atomic mass of chloride not a whole number?
Because relitive atomic masses are NEVER whole numbers.
Can explain in terms of isotopes why the relative atomic mass of atomic number 17 is not a whole number?
Mass number is the average of all the naturally occurring isotopes of that element. When calculated, this average is not a whole number.
Why is the atomic mass of an element not a whole number while the atomic number is?
The atomic number refers to the number of protons in the atom. Since the proton cannot be an in-between number, the atomic number will have to be a whole number. On the other hand, the atomic mass does not have to be a whole number because it is the mass of an atom and is roughly equivalent to the number of protons plus the average number of neutrons in that particular element.
What is the atomic mass on the periodic table?
Each element on the periodic table has two numbers: the atomic number and the relative atomic mass. The atomic number is the number of protons in the nucleus, and the relative atomic mass is the total number of protons and neutrons (so the difference between them is the number of neutrons). The relative atomic mass is always the higher of the two.
Hydrogens atomic mass number and relative atomic mass?
Hydrogen is a non metal element. Atomic mass number of it is 12.
What is the difference between Mass number and Relative of atomic mass?
Atomic mass is the average of the masses of the naturally existing (i.e. mixture of) isotopes of one specific element.The atomic mass number is the sum of the protons and neutrons in the nucleus of an atom (specific for one specific isotope).
The number of an element determines its?
it depends which number you are referring to. in the periodic table, the numbers referr to number of protons and then relative atomic mass. the larger number is relative atomic mass and the smaller number is the number of protons for example, chlorine, has a relative atomic mass of 35.5 and a proton number of 17
What do you do with an atomic number and an atomic mass?
The atomic number is the number of a chemical element in the periodic table of Mendeleev; the atomic number is equal to the number of protons and electrons. The atomic mass is the mass of an atom expressed in relative atomic mass units.
What is the mass number in argon?
The relative atomic mass is 39.95
What is the number of atomic mass in an atom?
Relative mass number of an electron is 0
What is the nearest whole number of atomic mass of potassium?
The nearest Whole number of atomic mass of potassium is 69
Atomic mass differnet from the atomic mass number why is that?
The atomic mass is an average, allowing for the relative abundances of different isotopes.
