The radius of a hydrogen atom is 0.0000000529177 a millimeter. Express this number as an approximation
The radius of a hydrogen atom is approximately 5.29177 × 10^-11 meters.
To express the radius of a hydrogen atom, which is 0.0000000529177 millimeters, as an approximation, we can round the number to a more manageable format.
Rounding to two decimal places, the approximation would be 0.00 millimeters.
To express the given radius of a hydrogen atom as an approximation, we can use scientific notation.
Scientific notation represents a number as a product of a coefficient (between 1 and 10) and a power of 10. In this case, the coefficient will be between 1 and 9.99, and the power of 10 will be determined by the number of decimal places to move the decimal point in the original number to obtain a coefficient between 1 and 10.
The given radius is 0.0000000529177 millimeters. To express this as an approximation, we can use scientific notation as follows:
0.0000000529177 = 5.29177 × 10^(-8)
In this representation, the coefficient is 5.29177, and the power of 10 is -8, indicating that the decimal point should be moved 8 places to the left.
So, the approximation of the radius of a hydrogen atom is approximately 5.29177 × 10^(-8) millimeters.
