What English physicist placed the elements according to their proton number?
Henry Mosely
What is the order of elements based on?
Proton number
What is the proton number also called?
The proton number is the atomic number.
Are elements organized by atomic weight and physical properties?
Elements are scientificaly organised according to their Proton numbers. Those with smaller proton numbers come first.
How is the no of proton determined in the proton?
You need to clarify this question. Do you mean, "How is the number of protons determined in the periodic table of the elements?"
Which of the 117 elements has a proton number of 53?
Iodine has 53 protons.
What elements have a lower proton number than fluorine?
Elements with a lower proton number than fluorine on the periodic table include elements such as helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, and neon. These elements have fewer protons in their nucleus than fluorine, which has 9 protons. The proton number, also known as the atomic number, determines the identity of an element on the periodic table.
Have scientists ever found elements with same number of protons?
Well, when two elements have the same number of protons, they are atoms of the same element. Each element has its unique proton number. If an atom has 1 atom, it is called Hydrogen. If it has 2, it is called Helium. If it has 20, it is called Calcium. However, the number of neutrons may differ. For example, in the case of Hydrogen, it may have no neutron, 1 neutron or 2 neutrons, and still be called Hydrogen. However, they are called 'isotopes', meaning members of the same element(same number of proton), but having different neutron numbers.
How does the periodic table list elements?
Elements are listed by the number of protons they contain starting with Hydrogen which has one proton.
What is the difference between isobar and isotope?
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
What is the proton number called when referring to the periodic table?
The proton number is also known as the atomic number when referring to the periodic table. It represents the number of protons in the nucleus of an atom, which determines its chemical properties and its unique place on the periodic table.
Are elements in a period arranged alphabetically?
NO!!! Elements in a Period are arranged by Atomic No. / Proton No. If we take PERIOD 1. . the two elements are Hydrogen and Helium, in that order. H**ydrogen , Hel**ium are NOT in alphabetical order.
