The element with 17 protons and 18 neutrons is chlorine, which has the atomic number 17. Its symbol is Cl, and it is located in group 17 (halogens) of the Periodic Table.
No, Mendeleev did not know about protons, neutrons, and electrons. He is best known for creating the periodic table of elements based on the properties of the elements without knowledge of the atomic structure. The discovery of protons, neutrons, and electrons came later with the development of atomic theory.
The table you are referring to is called the periodic table of elements. It organizes elements based on their atomic number, symbol, name, and other properties. It does not typically list the number of protons and neutrons for each element, but this information can be calculated based on an element's atomic number and mass number.
Elements differ in their atomic number, which determines the number of protons in the nucleus; atomic mass, which is the sum of protons and neutrons; and chemical properties based on electron configuration. Elements are arranged on the periodic table based on increasing atomic number and grouped by similar properties. Elements can exist in different forms, known as isotopes, which have the same number of protons but different numbers of neutrons.
All elements are made up of atoms, which consist of protons, neutrons, and electrons. Elements are categorized on the periodic table based on their number of protons, known as the atomic number. Elements can combine to form compounds through chemical reactions.
Protons and neutrons contribute most to the mass of an atom. Electrons have very low mass compared to protons and neutrons, so their contribution to the overall mass of an atom is negligible.
A list of elements, with some of their properties.
The sum of protons and neutrons is the atomic mass.
Because it has the atoms in the protons and neutrons
Cobalt has 27 protons, 27 electrons, and typically 32 neutrons.
no there are different elements, and you can check a periodic table for more information.
All atoms of chemical elements contain protons, neutrons and electrons.
by ectron protons and neutrons
Because it is elemental. That is: it is not an alloy. It has a unique number of protons and neutrons.
No they are made up of Protons, Neutrons and Electrons.
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.
It tells the amount of protons neutrons and electrons are in an atom.
Elements are made of one type of atom. Atoms are made of electrons, neutrons and protons
