Answer:
10 µm
Explanation:
Magnification = observed size ÷ actual size
So, Actual size = observed size ÷ magnification
In order to convert millimetre to micrometre, multiply by 1000
Actual size = 
∴ The actual size of the nucleus is 10 µm.
Answer:
ionic
Explanation:
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.
There are one valance electron in sodium so it needed to lose one valance electrons to complete the octet while chlorine needed one electron to complete the octet. Thus electrons lost by sodium atom is gained by atom of chlorine and form ionic compound.
2Na + Cl₂ → 2NaCl
Money for Marsupials. The reason for this is because the marsupials population is endangered, like koalas
Well i know you need carbon nitrogen and oxygen but there might be more
Answer:
