What elements are triads?
Döbereiner in 1817 showed that the combining weight, meaning atomic weight, of strontium lies midway between those of calcium and barium, and some years later he showed that other such “ triads ” exist (chlorine, bromine, and iodine [halogens] and lithium, sodium, and potassium [alkali metals]). J.-B.-A. Dumas, L. Gmelin, E. Lenssen, Max von Pettenkofer, and J.P. Cooke expanded Döbereiner’s suggestions between 1827 and 1858 by showing that similar relationships extended further than the triads of elements, fluorine being added to the halogens and magnesium to the alkaline-earth metals, while oxygen, sulfur, selenium, and tellurium were classed as one family and nitrogen, phosphorus, arsenic, antimony, and bismuth as another family of elements.
Why do the elements in the periodic table have different orbits?
The arrangement of the elements in the periodic table comes from the electronic configuration of the elements. Because of the Pauli exclusion principle, no more than two electrons can fill the same orbital. The first row of the periodic table consists of just two elements, hydrogen and helium. As atoms have more electrons, they have more orbits available to fill, and thus the rows contain more elements farther down in the table.
How many protons does hydrogen have?
The atomic number of an element is the number of protons in the nucleus of an atom of that element. Hydrogen has 1 proton, and oganesson has 118.
What are the elements that are related to the first seven?
Newlands proposed classifying the elements in the order of increasing atomic weights, the elements being assigned ordinal numbers from unity upward and divided into seven groups having properties closely related to the first seven of the elements then known: hydrogen, lithium, beryllium, boron, carbon, nitrogen, and oxygen . This relationship was termed the law of octaves, by analogy with the seven intervals of the musical scale.
Who proposed the periodic law?
Then in 1869, as a result of an extensive correlation of the properties and the atomic weights of the elements, with special attention to valency (that is, the number of single bonds the element can form), Mendeleyev proposed the periodic law, by which “the elements arranged according to the magnitude of atomic weights show a periodic change of properties.” Lothar Meyer had independently reached a similar conclusion, published after the appearance of Mendeleyev ’s paper.

The modern periodic table is based on the modern periodic law put forward by the English physicist Henry Moseley, which states that “the properties of elements are periodic functions of their atomic numbers”.
What is the atomic number of an element?
The atomic number of an element is equal to the total number of protons in the nucleus of the atoms of that element. The atomic number can provide insight into the electronic configuration of the element. For example, carbon has an electron configuration of [He] 2s 2 2p 2, since its atomic number is 6.
What is the number of protons in the nucleus called?
The number of protons in the nucleus is called the atomic number. The atomic number of each element is unique.
Why is the atomic number of each element unique?
While the atomic number always stays the same some elements have atoms with different atomic mass numbers. This is because some elements have a different number of neutrons in the nucleus.
How to find the mass of an element?
The number of protons and the number of neutrons shall determine the mass number of an element. Since the isotopes of an element have slightly different mass numbers, it calculates the atomic mass by obtaining the mean of the mass numbers for its isotopes.
How can periodic trends be observed?
Periodic trends in the properties of the elements can be observed down the groups and across the periods of the modern periodic table. Every chemical element has a specific atomic number, which provides insight into the number of protons present within its nucleus.
