Which element has mass number of 23?
Sodium is a metal element. Atomic mass of it is 23.
Why can an atom have more then one mass number but only one atomic number?
First of all, an atom can not literally have either more than one mass number or more than one atomic number. Different atoms of the same element can have different mass numbers but the same atomic number because the atomic number is the defining characteristic of an element, but many elements have isotopes that have different numbers of neutrons in their nuclei and therefore different mass numbers: Mass numbers are the sum of the numbers of protons and neutrons in the nucleus.
Does the atomic number of an element determine its mass?
Not by itself. The mass number is the sum of the numbers of protons and neutrons in he nucleus for each isotope of the element, or for elements with more than one stable isotope is an average depending on the natural abundance of the stable isotopes of the element.
What is the relationship between a atomic number and an atomic mass number?
Atomic number: number of protons in a nucleus unique to an element Atomic mass number: number of protons + number of neutrons in a nucleus. May be a small range of values for a given element. Very roughly the atomic mass number is double the atomic number. For large elements it is more than double.
Why does tellirium has a larger mass number than iodine?
Iodine is a non metal element. Atomic mass number of it is 127.
Which element has mass number of 23?
Sodium is a metal element. Atomic mass of it is 23.
What element can have the atomic number 118 and also the mass number 50?
No element can have those features; the mass can never be less than the atomic number in any element.
Which is usually the larger number the mass number of an element or the formula mass of a compound that contains the element?
The formula mass of a compound that contains the element would be a larger number than the mass number of the individual element. The individual element would simply be the mass of just that one atom, where as the compound would be the mass of that atom plus the other masses of the other atoms that make up the compound. ex. Oxygen-O has a mass number of about 16 grams. Water-H2O has a formula mass of 2 x mass of Hydrogen-H (about 1) + the mass of Oxygen-O 16 = 18 grams. A formula mass of 18 g is more than a mass number of 16 g.

Distinguish between the atomic number and mass number of an element?
The atomic number of an element is the number of protons in the nucleus of each atom of the element. Mass number is a property of a particular isotope of the element rather than of the element itself: The mass number is the sum of the numbers of protons and neutrons in the nucleus of each atom of the isotope.
Does the atomic number of an element determine its mass?
Not by itself. The mass number is the sum of the numbers of protons and neutrons in he nucleus for each isotope of the element, or for elements with more than one stable isotope is an average depending on the natural abundance of the stable isotopes of the element.
What is an aton with a different mass number than normal?
An isotope of the element. The mass number is the number of protons and neutrons in the nucleus.
What is the relationship between the atomic number and the atomic mass number?
Atomic number: number of protons in a nucleus unique to an element Atomic Mass number: number of protons + number of neutrons in a nucleus. May be a small range of values for a given element. Very roughly the atomic mass number is double the atomic number. For large elements it is more than double.

Is the sum of the numbers of protons and the number neutrons in an atom is the mass number?
It is the mass number for that particular form of the atom - that particular isotope. An element can exist as more than one isotope and the atom's mass number is the (weighted) average of the mass numbers of all its isotopes.
Why does tellirium has a larger mass number than iodine?
Iodine is a non metal element. Atomic mass number of it is 127.
Why is the mass number bigger than the atomic number?
The atomic number of an element is the number of protonsin its atom's nucleus. The mass number of an element is the number of nucleons (protons or neutrons) in its atom's nucleus. Except in the case of hydrogen, which has no neutrons, the mass number will always be higher.
