Elements on the Periodic Table are arranged by atomic number. This refers to the number of protons in the nucleus of that atom. Generally, atoms with higher atomic numbers will have a higher mass (due to more protons); however, the number of neutrons in the nucleus (isotopes of each element) will also affect the mass. An element with a lower atomic number but extra neutrons could have a higher Atomic Mass than an element with a higher atomic number. The atomic mass listed on the periodic table is an average of the naturally occurring distribution of isotopes of that element. For example, Cobalt (element #27) has an atomic mass of 58.9332 amu, whereas Nickle (element #28) actually has a lower atomic mass of 58.6934 amu.
They are arranged by increasing atomic number. Generally, there is also an increase in mass along groups and periods.
increasing atomic number (Z) as we look from left to right, the lighter metals appear on the left
false
Yes it is
The periodic law states that when the elements are arranged by increasing atomic number, there will be periodic repetition.
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
Now modern periodic table is arranged in order of increasing atomic number. The properties are found to be periodic when arranged in this pattern.
Atomic Number (amount of protons)
The present periodic table is arranged in order of increasing atomic numbers not the atomic weights , before modern periodic law the elements were arranged on the basis of atomic weights.
The periodic table used to be arranged by increasing atomic mass. Now, it is arranged by increasing atomic number (number of protons in an atom of element).
The elements are arranged in the increasing order of their atomic number and repeating properties.
The atomic number of each element is on the periodic table. The elements are arranged on the periodic table in order of increasing atomic number.
Elements are arranged in order of increasing atomic number. The atomic number is the number found at the top of each box on the Periodic Table. The atomic number is the number of protons in the nucleus of each atom of each element.
The periodic law states that when the elements are arranged by increasing atomic number, there will be periodic repetition.
the atomic number is the number of protons in a certain element. elements are arranged on the periodic table by atomic number in increasing order
In modern periodic table, elements are listed by increasing atomic number.
Periodic table contains elements arranged in rows and columns. It is done according to increasing atomic number.
He arranged the elements in the increasing order of their atomic masses and repeating periodic properties.
As the periodic table is arranged in order of increasing atomic number hydrogen is the first element in the periodic table as it has only one electron.
Now modern periodic table is arranged in order of increasing atomic number. The properties are found to be periodic when arranged in this pattern.
It is element 29 on the periodic table. The elements in the periodic table are arranged according to increasing atomic number. The atomic number is the number of protons in the element's atoms.
