A substance floats or sinks in another because of its relative density. Take ice floating in water for example. Water is more dense than ice so ice floats.
Mass is incorrect as the buoyancy or ability of an object to float depends on the mass per volume, which is equivalent to density.
Answer:
D
Explanation:
Silicon, element number 14 is the fourth element in the third period in the periodic table. Its electronic configuration is 1s^2 2s^2 2p^6 3s^2 3p^2.
The elemental symbol of the previous noble gas preceding the atom is replaced by the arrangement of the remaining electrons to form a noble gas configuration of an atom.
So for Silicon, we substitute [Ne] 1s^2 2s^2 2p^6 and the noble gas configuration can now be [Ne] 3s^2 3p^2.
