Two electrons fit in the first shell out from the nucleus and eight fit in the second. Every element with more protons than the two of Helium needs to work on shells outside the first one. one you get to ten, you have filled the first two shells.
In a water molecule, oxygen forms one covalent bond with EACH of TWO hydrogen atoms. As a result, the oxygen atom has a stable arrangement of 8 valence electrons. Each hydrogen atom forms only one bond because it needs only two electrons to be stable.
The answer should be D) electrical
Key differences between Mass and Weight
The weight may vary, but the mass is constant.
The mass is measured in kilograms (kg), while the weight is measured in newtons (N).
Mass refers to the amount of matter an object has, but the weight refers to the force of gravity acting on an object.
