D. Electrons orbit in a fixed shell
Considering that scientific notation has to move the decimal over so there is only one digit in the Tens place, that is the scientific notation.
Answer:
5 000 000 (5 million atoms)
Explanation:
Let us assume that a vanadium atom has a spherical shape.
diameter of a sphere = 2 x radius of the sphere
Thus,
Radius of a vanadium atom = 130 pm
= 130 x
m
The diameter of a vanadium atom = 2 x radius
= 2 x 130 x
= 260 x
m
Given a distance of 1.30 mm = 1.30 x
m,
The number of vanadium atoms required to span the distance = 
= 5000000
Therefore, the number of vanadium atom that would span a distance of 1.30 mm is 5 million.
Answer:urenium
Explanation: because his atomic number is 235
Answer:
I would say operation or symbol
Explanation:
But more an operation I'm sorry I don't really know what your learning so I can't say I know for sure
