Henry Moseley
atomic numbers
If the elements are arranged in the order of their increasing atomic numbers, there properties are repeated in a periodic manner.
basically? how they react.some scientist guy who was good with calculations predicted qualitys of elements like, ages ago, before they were discovered.he basically designed the periodic table.if you notice, its in groupsthe first column, alkali metals, get nasty with water or anything more acidicsodium + water = firesodium + pure sulfuric acid = boom-------------------------------------They are arranged in increasing number of protons, and with respect to the number of electrons in the outer electron shell.
The elements in the periodic table are arranged by their atomic number, which represents the number of protons in the nucleus of an atom. This arrangement helps to group elements with similar properties together in columns known as groups or families.
He arranged the elements in the increasing order of atomic mass and repeating periodic properties.
In the periodic table, the elements are arranged in order of increasing atomic number from left to right and top to bottom. This arrangement allows elements with similar chemical properties to be grouped together in columns known as groups or families.
Mendeleev's Periodic Table was different from Moseley's in that Mendeleev arranged the elements inÊthe table according to atomic masses while Mosley's periodic table was arranged accordingÊto atomic numbers that were increasing.ÊÊThe modern periodic table used today is based on the Moseley model.
The elements are arranged in order of increasing atomic number in the Periodic Table. The rows are called periods and the columns are called groups.
In the modern form of periodic table, all elements are arranged in increasing order of their atomic numbers. The periodic properties of elements are functions of their atomic weights.
Dmitri Mendeleev arranged the elements in his periodic table in order of increasing atomic mass and grouped elements with similar properties together. This arrangement helped him to identify periodic trends and predict the properties of undiscovered elements.
Mosley arranged elements in order of increasing atomic number
If elements are arranged in the increasing order of their atomic numbers after specific intervals elements having same number of valence electrons lies in the same group which shows they have same chemical properties.
