Did mosey make a periodic table based off atomic numbers?
Yes, Moseley made a periodic table depending on atomic number. Elements were arranged in order of atomic number.
What elements did the alchamists think they could make into gold?
Lead stupid or Atomic number 82
What two elements make up the atomic number?
All the elements have an atomic number. The atomic number is the number of protons found in the atom of a certain element. And to equalize themselves the atoms will usually have the same amount of electrons as protons so electrons also equal the atomic number. The atomic number is the number on the top of the box on the periodic table for each element. You must have been asking what two subatomic particles make up the atomic number. In that case it would be the proton and the electron because the neutron is so mall that chemist's usually nullify it.
How have microscopes help make the periodic table?
The periodic Table of elements groups the different elements through their electron configuration and number of Protons (atomic number) and also states atomic mass by adding the number of protons and number of electrons.And all of these are checked by microscopes.
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.
How are elements are arranged on periodic table?
Dmitri Mendeleev and Lothar Meyer first arranged the elements in the increasing order of atomic masses. Bohr and Henry Moseley then arranged the elements in the increasing order of atomic number.
What elements do helium make up?
The only element helium makes up is helium. Atomic number: 2 Atomic weight 4.00260 u (avg)
What contributions did Moseley make to development of The modern periodic table?
Mosley arranged elements in order of increasing atomic number
Why is the atomic number important to the atom?
The atomic number corresponds to the number of protons in an atom. Hydrogen is the first element on the Periodic Table of Elements because it only has one proton. The number of protons in an atom and the number of neutrons in an atom are what make atoms different.
What particles make up the atomic mass number of an element?
The atomic mass number of an element is determined by mass of the nucleus of an atom. Therefore the particles that make up the nucleus determine the mass number. These particles are protons and neutrons.The mass of the protons and neutrons do not vary between elements, but the number of each in the nucleus varies between elements and between isotopes of the same element.
What atom is used as a reference for the atomic masses of all other elements?
Carbon-12 was assigned an exact atomic mass to act as the standard for atomic mass of all other elements
Can germanium bond with other elements?
Yes, Germanium with the atomic number of 32 can combine with chlorine to make silicon phone cases
