We have to get the maximum number of electrons in an atom that can have the given quantum numbers.
(a) The maximum number of electrons in an atom that can have quantum number n = 5, l = 3,
= +3 is 2 (two).
(b) The maximum number of electrons in an atom that can have quantum number n = 3, l = 1,
= -1 is 2 (two).
Here, n= principal quantum number, l= azimuthal quantum number and
= magnetic quantum number.
l= 0 to (n-1) and
= -l to +l including 0.
(a) n = 5, l = 3,
= +3, this set of quantum number represents one 5f orbital which can contain maximum two electron of opposite spins.
(b) n = 3, l = 1,
= -1, this set of quantum number represents one 3p orbital which can contain maximum two electron of opposite spins.
Answer:
The empirical formula is =
Explanation:
Given that:- Mass of nickel = 2.241 g
Mass of the oxide formed = 2.852 g
Mass of the oxygen reacted = Mass of the oxide formed - Mass of nickel = 2.852 g - 2.241 g = 0.611 g
Molar mass of nickel = 58.6934 g/mol
Moles of nickel =
= 0.03818 mol
Molar mass of oxygen = 15.999 g/mol
Moles of nickel =
= 0.03818 mol
Taking the simplest ratio for Ni and O as:
0.03818 : 0.03818 = 1 : 1
<u>The empirical formula is =
</u>
Answer:O D to protect the environment from harmful chemicals

Answer: Scientific Theory
Explanation:
A scientific theory is a broad explanation for events that is widely accepted as true. To become a theory, a hypothesis must be tested over and over again, and it must be supported by a great deal of evidence. People commonly use the word theory to describe a guess about how or why something happens.
