Hydrogen is the first element in theperiodic table, meaning it has anatomic numberof 1 or 1 proton in each hydrogen atom. The name of the element comes from the Greek wordshydrofor "water" andgenesfor "forming," since hydrogen bonds with oxygen to form water (H2O). Robert Boyle produced ...
Just the facts Atomic number (number of protons in the nucleus): 1 Atomic symbol (on the Periodic Table of Elements): H Atomic weight (average mass of the atom): 1.00794 Density: 0.00008988 grams per cubic centimeter Phase at room temperature: Gas ...
Location of H on the Periodic Table Hydrogen Atom Properties Hydrogen Uses Hydrogen Facts Lesson Summary Frequently Asked Questions What is hydrogen made of? Hydrogen is an element, so it is a pure substance. Its atom is extremely simple with only one electron and one proton. ...
This arrangement displays more patterns and connections between the elements than are seen in the regular format. It fits more facts and so gives better guidance to useful predictions.doi:10.1007/s10698-006-9027-5Michael Laing61 Baines Road Durban Republic of South Africa...

Though hydrogen is assigned to the IA group in the periodic table, at low pressure it is similar to halogens rather than alkalis, with a high electronegativity and a tendency to form covalent bond with itself. At ambient conditions it exists as diatomic molecular gas, instead of in a BCC ...
Based on the principle that alloying between the neighbors in periodic table of elements is easy to happen without structural aberration, various foreign metals (M = Ir, Rh, Pd, Ag, and Au) with the period/group adjacent to Pt come into sight. Compared to that of CoP, the calculated...
Give a reason why hydrogen can be placed in group 1[IA] and group 17[vIIA] of the periodic table. 2. What similarities does it show with group 1[IA] and group 17[VIIA]. With special reference to valency electrons and ion formaton and examples. 3. How does hydrogen occur in the ...
