Electrons ruminate around the nucleus in particular circular path known as orbit called shell.
Electronic configuration is the dispense of electrons.
Electronic configuration is also known as electronic structure.
Also termed as spatial methodize.
More than one orbital in the electron shell is known as subshell, they have similar energy level.
In Electronic configuration there are four shell present namely k,l,m,n and there are 4 sub-shell namely s,p,d,f.
As we know that every subshell fills gradually s max 2 electrons p - 6 , d - 10 and f - 14.
So,
According to questions,
Thge element has configuration 1s2 2s2 2p4 hence 8 electrons.

Explanation:
Hot air balloons work because hot air rises. By heating the air inside the balloon with the burner, it becomes lighter than the cooler air on the outside. This causes the balloon to float upwards, as if it were in water.
Answer:
None of the species in the equation have undergone either oxidation or reduction
Explanation:
The easiest way to see if oxidation or reduction has happened is to compare oxidation numbers of each and every species before and after the reaction.
Calcium is two before the reaction and two after the reaction
Hydrogen is -1 before the reaction and -1 after the reaction
Sodium is one before the reaction and one after the reaction
Iodine is -1 before the reaction and -1 after the reaction.
For an oxidation to happen an increase in oxidation number has to happen.
For a reduction to happen, a decrease in oxidation number has to happen. None have happened
Answer:
Symbol is Sn
Explanation:
From the periodic table, the element that has an ionic number of 50 and electronic structure of 1s² 2s² 2p^(6) 3s² 3p^(6) 3d^(10) 4s² 4p^(6) 4d^(10) 5s² is known to be Tin.
The symbol for Tin is written as Sn
MO Diagram of C₂⁻ is shown below,
Bond order is calculated as,
Bond Order = [# of e⁻s in BMO]-[#of e⁻s in ABMO] / 2
Where,
BMO = Bonding Molecular Orbital
ABMO = Anti-Bonding Molecular Orbital
Putting values,
Bond Order = [9]-[4] / 2
Bond Order = 5 / 2
Bond Order = 2.5
