yes
The atomic number is the number of protons that the element has.
Yes. There are 117 of them that have been observed. They are organized into the Periodic Table of Elements based on the number of protons in the in nucleus.
It depends on what atom it is...If it is a Hydrogen atom, it is 1If it is a Helium atom, it is 2...Find the element you want on the Periodic Table of Elements, and there should be two numbers by that element. The smaller of the two numbers tells you the number of protons that the element has.
The modern periodic table does a lot of things. It organizes elements in order of electron orbitals for one thing (1s, 2s, 2p, 3s, 3p, 4s, ect..). It also has all noble gases stacked on top of each other helping to determine the columns of 1-8 valence electrons. It seperates all metals from nonmetals and elements in the same column will have similar physical and chemical properties.
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.
The atomic number is equal to the number of protons in the nucleus.
the number of protons in the nucleus.
The number of protons in a nucleus depends on the specific atom. In the Periodic Table of elements, the number of protons a given element has is equal to its atomic number.
The number of protons in a nucleus depends on the specific atom. In the Periodic Table of elements, the number of protons a given element has is equal to its atomic number.
The number of protons in a nucleus depends on the specific atom. In the periodic table of elements, the number of protons a given element has is equal to its atomic number.
Number of protons in the nucleus (=atomic number)
Mass number - the number of protons and neutrons present in the nucleus.
The atomic number (number of protons in the nucleus)
Periodic Table
The atomic number is the number of protons in the nucleus of an element. It defines the element. No two different elements can have the same number of protons. It is used to lay out the periodic table because the table shows the elements in increasing numbers of protons.
