What is the electronegativity of hydrogen?Question:What is the electronegativity of hydrogen?Hydrogen:Hydrogen is the most common element in the known universe. It is represented by H and has the atomic number 1. It is classified as a reactive nonmetal and is a colorless gas.Answer...
of each element. Each row is a period and each column is a group. All groups are given a specific number and many of them are also given a specific name. Elements in a group share certain common chemical properties, including the number of valence electrons present in their neutral atoms....
Producing hydrogen takes energy because hydrogen atoms don't exist on their own — they are almost always stuck to another atom, often another element. (On earth, hydrogen is particularly abundant in the form of water, or H2O.) Creating pure hydrogen requires breaking those molecular bonds. In...

The meaning of an ‘element’ is a favourite topic for argument among off-duty chemists. We agree (right?) that hydrogen is an element – but what do we mean by that? Is molecular hydrogen gas an element? Or the isolated hydrogen atom? Or are we referring not to some actual substance...
Like hydrogen, it is a colorless and odorless gas. However, it is an unreactive element, and the lightest of the group called the "noble gases." It therefore doesn't play a role in biology, and isn't used in many chemical processes in industry (aside from as an inert substance), ...
Carbon makes up the backbone of fats, carbohydrates and proteins, so this element is a major building block of the body and the foods we use to fuel it. Related: How many organs are in the human body? Coming in at No. 3 is hydrogen. There are more hydrogen atoms in the human body...

Step 1: Determine the total number of valence electrons in the Formaldehyde. Hydrogen, a Group IA element, has one electron in its outer shell. Oxygen, a Group VIA element, has six electrons in its outer shell. Carbon is a Group IVA element with four electrons in its outer shell. Hence...
