To satisfy the law of conservation of mass
The highest sequence for this shell is the number 2, preceding both the s and p in the diagram. This means that the outermost shell is the second level shell. In this shell, there are 7 electrons, 2 in the 2s orbital and 5 in the 2p orbital.
As a side note (not sure if this is a typo), the electron structure for fluorine begins with a 1s2, not a 1s1.
Answer: if this is true or false, then this is false, something that is cold has slow moving particles, fast moving ones generate heat which will make it warm, this object has potential energy not kinetic.
Answer:
<u><em>Pangaea</em></u>
<u><em>Alfred Wegner</em></u>
<u><em>plate tectonics</em></u>
Explanation:
What did Earth look like 250 million years ago? The continents of Earth were clustered together in formation that a scientist named<em> </em><u>Pangaea</u><u><em>.</em></u>The scientist that named "Pangaea" was a German scientist by the name of <u>Alfred Wegner.</u> He theorized that "Pangaea" split apart and the different landmasses, or continents, drifted to their current locations on the globe. Wegener's theories of plate movement became the basis for the development of the theory of <u>plate tectonics.</u>
