Scot has a 50 g sample of sandstone. the sandstone is formed by sedimentation, compaction, and cementation of 50-g of sand particles. based on this information, what can scot conclude?
a) mass is conserved in the rock cycle.
b) the structure of sand remains the same.
c) the sand retains its properties within sandstone
d) the volume of the parts is conserved in the rock cycle.

answer; blank (1); /// (2)///(3)///highblank(4)//low;

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
