Where can you find the mass number of an element on the periodic table?

The mass number or Atomic Mass number of an element is simply the number protons and neutrons in the atom's nucleus. Recall that the number of protons in the nucleus of an atom determines its elemental identity. Recall, also, that the number of neutrons in the nucleus of a given atom of an element can vary giving rise to different isotopes of that element. Hydrogen, the simplest of the elements, has a nucleus of one proton. But some atoms of hydrogen have a proton and a neutron in the nucleus. And there is an even rarer occurance of hydrogen with its proton and two neutrons in the nucleus. The mass numbers for these three isotopes of hydrogen are 1, 2 and 3 respectively. Helium has a nucleus that has two protons in it. Almost all the helium has an atomic mass number of 4, meaning that there are two protons and two neutrons in the nucleus. But there is a tiny percentage of helium that has only one neutron in the nucleus, and has mass number 3. A link to the Wikipedia article entitled Mass Number is provided.

∙ 12y agoIt is actually very simple......what you have to do is that when you look at an element let's say potassium which is in the group I ,left hand side of the Periodic Table it will be given as k- which is the symbol and19 which is written at the bottom and 39which is written at top of the element's symbol and that's the mass no.

∙ 11y agoNo. Mass number refers to a particular isotope of an element. It is the sum of the protons and neutrons in the nucleus of the atoms of the isotope. Atomic weight is found on the periodic table. Atomic weight of an element is the weighted average of the masses of naturally-occurring isotopes of that element.

∙ 9y agoWe can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.

Can you find the atomic number of an element on the periodic table?
Atomic number of an element can be found on the periodic table. It is located at the upper left-hand corner of the table.
How can you find the mass number of an element?
look on the periodic table of the elements
How can you find an element?
I'm assuming you mean "how can you find an element on the periodic table?" The periodic table is strategically placed. You can either look for the atomic number (the number at the top-- the number of the protons in one atom), or you can just look for the Element Symbol. The periodic table from left to right is sorted by increasing atomic number. The periodic table from top to bottom is sorted by increasing number of energy levels (the levels in which the electrons are in).
Can you find the atomic number of an element in the periodic table?
Almost every periodic table includes the atomic number, and even if it doesn't, you could always count.
What is the number of atomic number?
if you look @ the periodic table, you will find the tiny # above the element... that is its atomic #.

How do you find the atomic number of an element?
Look it up in "periodic table of elements" You can find the number of a particular element by looking at the Periodic Table; you can also do this by counting the number of protons in the nucleus.

How do you find the number of neutrons on an element?
use a periodic table look at the atomic number

Where would you find the atomic number of an element on a periodic table?
The top left number is the atomic number
Atomic number is equaled to what on the periodic table?
Atomic number is the bottom number on an element in the periodic table. It is the proton number, so tells you how much protons are in an element. EXTRA: you can find the neutron number by subtracting the mass number from the proton number.
Is silver a suspension?
No, it is a chemical element. You could find it in the periodic table as number 47.
Where do you find the element calcium?
in basically any fruit and number 20 on the periodic table
What is the atomic number of (as)?
