41 of the 118 known elements have names associated with, or specifically named for, places around the world or among astronomical objects. 32 of these have names tied to the places on Earth, and the other nine are named after to Solar System objects: helium for the Sun; tellurium for the Earth; selenium for the Moon; mercury (indirectly), uranium, neptunium and plutonium after planets (Pluto ...
The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows ("periods") and columns ("groups"). It is an icon of chemistry and is widely used in physics and other sciences.
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [1] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
Latin grammar. In linguistics and grammar, conjugation has two basic meanings. [1] One meaning is the creation of derived forms of a verb from basic forms, or principal parts. The second meaning of the word conjugation is a group of verbs which all have the same pattern of inflections. Thus all those Latin verbs which in the present tense have ...
This is a list of Latin words with derivatives in English (and other modern languages). Ancient orthography did not distinguish between i and j or between u and v. Many modern works distinguish u from v but not i from j. In this article, both distinctions are shown as they are helpful when tracing the origin of English words.
People. Chemical elements are sometimes named after people, especially the synthetic elements discovered (created) after c. 1940. Very few are named after their discoverers, and only two have been named after living people: the element seaborgium was named after Glenn Seaborg, who was alive at the time of naming in 1997; [5] and in 2016 ...
Latin phonology is the system of sounds used in various kinds of Latin. This article largely deals with what features can be deduced for Classical Latin as it was spoken by the educated from the late Roman Republic to the early Empire. Evidence comes in the form of comments from Roman grammarians, common spelling mistakes, transcriptions into ...
This is a list of chemical elements and their atomic properties, ordered by Atomic number. Since valence electrons are not clearly defined for the d-block and f-block elements, there not being a clear point at which further ionisation becomes unprofitable, a purely formal definition as number of electrons in the outermost shell has been used.
