It is when 2 surfaces touch each other and the electrons move from one object to another.
Half of the land sides to the right and the other too the left.
Answer: If an Atom has 12 Electrons then if it is a Neutral atom then the Atomic Number of the Atom will be 12.
The Electronic Configuration of Element with Atomic Number 12 will be :
⇒ 1s² 2s² 2p⁶ 3s²
We can notice from the Electronic Configuration that :
Given atom has 2 electrons in the 1st shell.
⇒ In the Shell : n = 1
Number of Electrons = 2
In the similar way : Number of Electrons in 2nd shell = 2 + 6 = 8
⇒ In the Shell : n = 2
Number of Electrons = 8
In the similar way : Number of Electrons in 3rd shell = 2
⇒ In the Shell : n = 3
Number of Electrons = 2
Explanation:
The number 250 mg tablets of Metronidazole that are needed to make 150 ml of suspension containing 100 mg/ml
250mg= 150 ml
what about 100 ml = ? Mg
by cross multiplication
150 ml x 250 mg/100 ml = 60 Mg of 250 mg is needed
