atomic weights is usually the number that has decimal points. so whenever you see a number with decimal point on Periodic Table, then that is the Atomic Mass.

What subatomic particle makes the periodic table in the order of elements that it is in?

The order of the periodic table is made according to the atomic weights of the elements. The number of protons and neutrons in the nucleus make the atomic weight. Protons make the elements in order of the periodic table.


What are the masses on the periodic table mostly not whole numbers?

1. First cause: the atomic weight is the sum of the weights of protons, neutrons ans electrons.; they don't have masses as integers. 2. Second cause: also occurs the so-called mass defect. Note: no atomic masses for elements but atomic weights is correct.


Two isotopes of an element have different?

Two isotopes of an element have the same atomic number (number of protons) but have different mass numbers (sum of protons and neutrons). This means that they will differ in the number of neutrons despite being the same element.


What basic information is contained in the Periodic table of elements?

The periodic table include only chemical elements each has a unique atomic number that represents the number of protons in its nucleus. Most elements have differing numbers of neutrons among different atoms these are referred to as isotopes.


What is unique about an isotope?

Isotopes of an element differ from each other by having different numbers of neutrons. For example: 1H (hydrogen), 2H (deuterium), 3H (tritium) are isotopes. They have the same number of protons (1) but different numbers of neutrons (0, 1, and 2 respectively).

How many protons are there in carbon?

There are 6 protons in carbon. The weights of the different isotopes are due to different numbers of neutrons.

How many neutrons and protons are there in an atom?

The number of protons is equivalent to the atomic number which can be got from the periodic table. The number of neutrons is the atomic weight minus the number of protons. Again, this information is available from the periodic table.


Total number of protons and neutrons in the atom is?

The total number of neutrons in an atom is known as its atomic mass. The sum of all the atomic weights of isotopes of a particular element is known as an element's atomic weight. Atomic weights are decimal numbers for this reason.

The importance of periodic table-of-elements?

u can easily apply the knowledge of periodic table say, atomic weights, atomic numbers, no. of protons or electrons, no. of neutrons, many more to fill the s,p,d,f shells, to identify an element when it's group or period number is given through 2,8,8,18,18,32 method

What is a example of a non atomic number?

Mass number is the sum of neutrons and protons. It is equals to total of their weights. As an example hidrogen-2 (deuterium) has a mass number of 2.

Why is atomic mass for an element an average on the periodic table?

The atomic mass is an average because most atoms have isotopes sometimes up to 10 or more. These all have different numbers of neutrons and subsiquently different weights. For this reason an average of these weights needs to be used for the atomic mass.
