leading zeroes to the left of a decimal point. andtrailingzerostotheleftofaninvisibledecimalpoint.
Explanation:
All nonzero digits are significant figures. Example: 713 has three significant figures. 18,991 has five significant figures.
Zeros located between two nonzero digits are significant figures. Example: 505 has three significant figures. 17,009 has five significant figures.
Zeros at the ends of numbers are only significant if there is a decimal point in the number. Example:502.00 has five significant figures (5,0,2,0,0). 5020 has three significant figures (5,0,2) 100,000 has one significant figure (1)
Zeros that come before the first nonzero digit are not significant. Example:0.0007 has one significant figure (7). 0.0970 has three significant figures (9,7,0)
Like stratovolcanoes, they can produce violent, explosive eruptions, but their lava generally does not flow far from the originating vent. Cryptodomes The 1980 eruption of Mount St. Helens was an example; lava beneath the surface of the mountain created an upward bulge which slid down the north side of the mountain.
Answer:34.55 explanation:number of neutrons=mass number-atomic number the mass number for copper is 63.55 so you do 63.55-29 (29 is the atomic number) and you would get 34.55
