<span>Na (sodium) is highly electropositive. Its has 1 electron in its outermost orbit which is transferred to an electronegative atom to form an ionic bond.
It only needs to get rid of one valence electron to take part in a reaction. That's how it's highly reactive.</span>
True
It’s true because models are based on real world problems to help grasp a understanding of the problem
Answer:
high electronegativity difference between oxygen and hydrogen
Explanation:
The electronegativity value of O and H are 3.5 and 2.1 respectively. The electronegativity difference of the O-H bond in H₂O is 1.4.
- When the elctronegativity difference between two atoms in bond is below 0.5 the bond is nonpolar covalent.
- When the elctronegativity difference between two atoms in bond is between 0.5 and 2.0 the bond is polar covalent.
- When the elctronegativity difference between two atoms in bond is above 0.5 the bond is ionic.
Thus the O-H is a polar covalent bond. This explains the polarity in water molecules.
Answer:
2000
Explanation:
So the equation of volume of a rectangular solid is:
V= l * w * h
Where l is length w is width and h is height
To find the volume:
V= 40 * 10 * 5
V= 400 * 5 ( multiply 40 and 10 to get 400)
V= 2000 ( multiply 400 and 5 to get 2000)
The unit for volume is in this case.
