Answer : The correct option is, (A) 8
Explanation :
Octet rule : It is the tendency of atoms to have eight electrons in the valence shell. When the atoms have fewer than eight electrons then they tend to react and form the more stable compounds.
Or we can say that the atoms attempt to get a noble gas electron configuration, which is eight valence electrons.
For example : As we know that the sodium has one valence electron, so if giving it up then the result in the same electron configuration as the neon and chlorine has seven valence electrons, so if it takes one it will have eight and the result in the same electronic configuration as the argon.
Hence, the correct option is, (A) 8

Answer:
Li2O+H2O---->(2)LiOH
Explanation:
you have to balance the equation and not all the blanks have to be filled all the time but if it makes it easier for you in the first 2 question marks you can put a 1 which isnt necessary but if ur a visual person it will help.
hope this helps im litterally learning the same thing as u lol
Answer:
1,1,2
Explanation:
this was correct for me, if it wasnt correct check if youre on the right question
Answer : The correct option is, meter
Explanation :
S.I : It is known as the international System of Units. It is defined as a scientific method to express the magnitude of the several basics units.
There are seven basic units in the system from which the other units are derived.
The seven base unit are, meter for length, kilogram for mass, second for time, ampere for current, kelvin for temperature, mole for amount of substance and candela for intensity.
As per question, the S.I unit of length of a strip of zinc metal is, meter.
Hence, the correct option is, meter
The Si unit for length is meters.
B) nitrogen (N)
C) silicon (Si)
D) sulphur (S)
The element that has four total electrons in its outer P orbitals is
Sulphur (s) (answer D)
Sulphur is in group 16 and period 3 in the periodic table therefore Sulphur is in atomic number 16.
Sulphur (S) electronic configuration is 1S2 2S2 2P6 3S2 3P4 or [Ne] 3S2 3P4 therefore the 3P4 subshell of sulphur has only 4 electrons.
