Which number is the same as 8.7 x 10^-2?<br><br>A.0.087 <br>B.0.08 <br>C.0.0087 <br>D.0.87
Butoxors [25]
This correct option is C.
10^-2 = 0.001
8.7 * 10^-2 = 8.7 * 0.001 = 0.0087
Thus, 8.7 * 10^-2 is equivalent to 0.0087.

How many places are there for electrons in the third shell of an atom?
Dafna1 [17]
Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.
