Answer:
Element in the same group have similar chemical properties.
Answer:
The answer is 'All of the above'
Explanation:
because the hydrogen ions are represented by the symbol H+, they increase the PH value of a solution if less amount is added but they decrease the PH value of a solution if a larger amount of hydrogen ions are added but still they increase the PH value, and of course, they contribute to a solution by a base.
H2O has a bent structure. The oxygen atom is in the center, and the hydrogen atoms are attached but pointing downward. It's not linear because there are two unshared pairs of electrons on oxygen that take up their own spaces.
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 = ±
.
