What are the units of measurement for atomic radius?

Units used to measure atomic radius:

Angstroms (Å): This the most common unit used. Equivalent to 1.0 x 10-10 meters.

Nanometer (nm): Equivalent to 1.0 x 10-9 meters.

Picometer (pm): Equivalent to 1.0 x 10-12 meters.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
