Answer:
Lithium and francium belong to the same group because they both have the same number of valence electron. Having the same number of valence electron puts them in the same group. Group members possess similar properties. So Lithium and francium have similar properties because they have the same number of valence electron.
Explanation:
Answer: Your code returns a number of 99.123456789 +0.00455679
Ok, you must see where the error starts to affect your number.
In this case, is in the third decimal.
So you will write 99.123 +- 0.004 da da da.
But you must round your results. In the number you can see that after the 3 comes a 4, so the 3 stays as it is.
in the error, after the 4 comes a 5, so it rounds up.
So the final presentation will be 99.123 +- 0.005
you are discarding all the other decimals because the error "domains" them.
I believe it is A bit not completely sure
Inner-belt asteroids tend to be rich in SILICATE, whereas outer-belt asteroids tend to be rich in CARBON. An asteroid is a rocky object (much smaller than a planet), which orbits around the Sun.
The asteroids are composed of different elements (e.g., carbon, nitrogen, hydrogen, oxygen, silicate, etc).
The asteroid belt is a region in the Solar System, located between the orbits of Mars and Jupiter.
The size of the asteroids localized in the asteroid belt range from a few meters to almost 1000 kilometers (km) wide.
Approximately half mass of the asteroid belt is composed of only four asteroids (i.e., Ceres, Vesta, Pallas, and Hygiea).
