The correct answer Organism
Some elements that are not abbreviated with one or two letters on the periodic table are Ununoctium (Uuo) and Ununtrium (Uut).
In order to find out the number of electrons present in s orbital of Phosphorous we have to write the electronic configuration of phosphorous.
As the Atomic number of Phosphorous is 15 so it will have 15 electrons in neutral state. So,
P = 15 = 1s², 2s², 2p⁶, 3s², 3p³
Now analyzing electronic configuration, we found that it contains 3 s orbitals, i.e. 1s, 2s and 3s, and each s orbital is completely filled with two electrons each.
Result:
Therefore, a total of six electrons are present in all s orbitals of neutral Phosphorous Atom.
Answer:
D
Explanation:
because convex lenses bend light inward
Answer:
The Earth:
- Is tilted 23 1/2° on its axis
.
-
Rotates from west to east
.
-
Bulges slightly at the equator
.
-
Revolves around the sun once every 365 1/4 days
.
Explanation:
The only option that is incorrect is the first one - The Earth has a circular orbit around the sun-. Although the Earth has an orbit around the sun, this one is not circular, it is elliptical, this is similar to an inclined oval, and the planet rotates in this orbit with an inclination on its axis of 23 1/2º.
As well as the shape of the orbit is not circular, the shape of the Earth is not equal in all its parts, it is wider in the equator in comparison with the North and South Poles.
It rotates from west to east in its axis, and it takes 365 1/4 days to complete a round in its orbital.
