Yes - it is the first element in the Periodic Table
H2(hydrogen)
It is neither and EXAMPLE Nor a MIXTURE. It is an elemental gas , found in the Periodic Table in position No. .1.
An example of a gas element is helium, which is a noble gas commonly used in party balloons and airships.
No, HBr is not an element. It is a compound made up of the elements hydrogen (H) and bromine (Br).
For example, water reacts with zinc, releasing hydrogen, an element.
it's an element!
Hydrogen is an element. So the only element in hydrogen is hydrogen.
Take the element "Iron" then the symbol for the element is "Fe" and "Fe" is also the symbol for a single atom of the element in a chemical equation.
Not quite. You can have an atom of an element, for example an atom of Hydrogen, but not a Hydrogen of an atom. The parts of an atom are protons (positively charged), neutrons (no charge), and electrons (negatively charged).

Formula HBr represents the compound hydrogen bromide, which is an example of a binary acid. Binary acids consist of hydrogen and one other element from Group 16, typically a halogen such as bromine in the case of HBr.
Oxygen, carbon, nitrogen, hydrogen, calcium are all elements.
