Answer: They are typically smaller than spiral galaxies.
Some show evidence for prior collision or close encounter with another galaxy.
They exhibit vigorous star-forming activity.
Irregular galaxies are typically smaller than spiral or normal ellipticals, of irregular form, and without spiral arms. Irr I galaxies are often characterized by lots of gas, dust, and associated star formation. Irr II galaxies have forms that indicate prior collisions or close encounters with other galaxies. Irregular galaxies are one of the most common types of galaxies.
Please don’t listen to those people who always put links those are scams. The answer is the kidney, ureters, bladder, and urethra. This system filters your blood,removing waste and excess water. Your welcome!
Proton, the gold foil experiment indicated that the nucleus has a positive charge.
A visual representation of covalent bonding which represents the valence shell electrons in the molecule is said to be a Lewis structure. The lines represents the shared electron pairs and dots represents the electrons that are not involved in the bonding i.e lone pairs.
Number of valence electrons in each atom:
For Carbon,
= 4
For Hydrogen,
= 1
For Nitrogen,
= 5
The Lewis structure of
is shown in the attached image.
The formula of calculating formula charge =
-(1)
where, F.C is formal charge, V.E is number of valence electrons, N.E is number of non-bonding electrons and B.E is number of bonding electrons.
Now, calculating the formal charge:
