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 else can I help you with?
What are atoms that have the same number but different weights?
Atoms that have the same number of protons but different weights are called isotopes. Isotopes of an element have the same atomic number (number of protons), but a different atomic mass (sum of protons and neutrons) due to varying numbers of neutrons.
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 atoms with mor neutrons than protons?
Atoms with more protons than neutrons are simply isotopes of an element. Atoms of an element always have the same number of protons. However, the number of neutrons can vary and can be higher, lower, or equal to the number of protons.
Can isotopes of an element have the same number of neutrons?
Two different isotopes of an element have different numbers of neutrons. That's what an isotope is. So, no, isotopes of an element can not have the same number of neutrons.
Why Halogens are not identical?
The atomic weights are different. This means more protons and neutrons in the nucleus and thus more total electrons. This in turn means the outer electrons are further away from the nucleus and not as tightly bound which cahnges the reactivity and electronegativity.
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.
What are atoms that have the same number but different weights?
Atoms that have the same number of protons but different weights are called isotopes. Isotopes of an element have the same atomic number (number of protons), but a different atomic mass (sum of protons and neutrons) due to varying numbers of neutrons.
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 atoms with mor neutrons than protons?
Atoms with more protons than neutrons are simply isotopes of an element. Atoms of an element always have the same number of protons. However, the number of neutrons can vary and can be higher, lower, or equal to the number of protons.
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
Can isotopes of an element have the same number of neutrons?
Two different isotopes of an element have different numbers of neutrons. That's what an isotope is. So, no, isotopes of an element can not have the same number 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.
Why Halogens are not identical?
The atomic weights are different. This means more protons and neutrons in the nucleus and thus more total electrons. This in turn means the outer electrons are further away from the nucleus and not as tightly bound which cahnges the reactivity and electronegativity.
What are element that differ in the number of neutrons known as?
Isotopes are elements that differ in the number of neutrons they have. Isotopes of an element have the same number of protons in their nuclei but different numbers of neutrons, resulting in varying atomic weights.
What are atoms that have the same number of protons but different mass number?
Atoms with the same number of protons but different mass numbers are called isotopes. Isotopes have the same atomic number but different atomic weights due to variations in the number of neutrons in the nucleus.
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.
