Answer:
I believe the molecular formula is MnBr2·4H2O or Br2H8MnO4
Explanation:
The Geiger Counter. Geiger counters are used to detect radioactive emissions, most commonly beta particles and gamma rays. The counter consists of a tube filled with an inert gas that becomes conductive of electricity when it is impacted by a high-energy particle.
Hope That Helps!!!

Answer:
Hydrogen-1
Explanation:
Not sure what kind of explanation is needed for your question, because it doesnt specify.
The easiest should be:
Average mass of an element is calculated as the sum of the multiplication of each isotope by its percentage
And the mass of the hydrogen is 1, therefore the more abundant is hydrogen-1
I guess examples of solid and gas???? You have to be more descriptive.....
Copper is formed of copper atoms, which are closely clustered together. If observed closely, one could witness the movement of electrons between the atoms of the copper. Each copper atom turns into a positive ion by losing one electron. Thus, copper is a lattice of positive copper ions with the movement of free electrons among them.
Due to movement of electrons freely through the metal, they are also known as conduction electrons. The presence of these conduction electrons makes the copper a good conductor of electricity and heat.
