Answer:
B
Explanation:
Light travels faster than sound.
Explanation:
It is known that the maximum value of ml is equal to the vale of l. But the minimum value of n is as follows.
n = l + 1
where, n = principle quantum number
l = azimuthal quantum number
Values of n can be 1, 2, 3, 4 and so on. Whereas the values of l is 0 for s, 1 for p, 2 for d, 3 for f, and so on.
Also, "m" is known as magnetic quantum number whose values can be equal to -l and +l.
- Electronic configuration of Rb is . So here, n = 5, l = 0, m = 0 and s = ± .
- Electronic configuration of is . So here, n = 3, l = 1, m = -1, 0, +1, and s = ± .
- Electronic configuration of is . So here, n = 4, l = 2, m = -2, -1, 0, +1, +2 and s = ± .
- Electronic configuration of F is . So here, n = 2, l = 1, m = -1, 0, +1, and s = ± .
Answer:
This involves negatively charged particles (electrons) jumping to positively charged objects. When you rub the balloons against the fabric they become negatively charged. They take some of the electrons from the fabric and leave them positively charged.
Explanation:
Negative charges attract to positive charges. If a balloon is not rubbed with the wool cloth, it has an equal amount of negative to positive charges, so it will attract to a rubbed balloon. When both balloons are rubbed with the wool cloth, the both receive negative charges, so they will repel each other.
