Hydrogen is the first element in the periodic table. It is a very light gas with unique properties. Hydrogen has a low density and is colorless, odorless, and tasteless. It is highly flammable and can react explosively with oxygen. In nature, hydrogen is found in various forms. It is pres...
Help Dr. One get the periodic table ready in time! By directly observing the elements’ characteristics, testing their flame color, and investigating trends in atomic properties, your mission is to figure out where a number of fallen out elements belong. ...

Learn the definition of diatomic elements, where to find diatomic elements on the periodic table, how diatomic elements are formed, and how to remember them. Related to this Question What is the chemical formula for fluorine gas? What is the chemical formula of fluorine in standard state?
S2), which is built from periodic table and summarizes the most fundamental chemical properties of elements and microscopic associations among elements. The key innovation in Matformer lies in Multi-scale Atom-attention (MSA) for understanding the interactions between different defined atoms in a ...
Nitrogen is the first member in Group 15 (VA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to one another. Nitrogen is in a family group named after itself. Other elements in the nitrogen family are phosphorus, arsenic, antimony, and bi...
Upon Ramsay’s discovery of the remaining natural noble gases and his proper positioning of this new family of elements within Mendeleev’s periodic system, visionaries came forth who espoused the Periodic Table and noted trends within it that suggested the possibility of compound formation by ...
Chemical investigations of superheavy elements in the gas-phase, i.e. elements with Z≥104, allow assessing the influence of relativistic effects on their chemical properties. Furthermore, for some superheavy elements and their compounds quite unique gas-phase chemical properties were predicted. The...
