Fluorine is in the period 2, group 17 of the Periodic Table of Mendeleev.
The f-block elements in period 7 are known as the actinides.
To determine the energy level of the f-orbital in a particular period, consider the principal quantum number (n) of the period. The energy level of the f-orbital follows the pattern 4n, where n is the principal quantum number. This means that for each period, the energy level of the f-orbital will be 4 times the principal quantum number of that period.
The f-block elements in period 7 are known as the actinides.
The f-block elements have 14 elements in a period because the f orbital in the f-block can hold a maximum of 14 electrons. This results in 14 elements being accommodated in one row or period of the f-block in the periodic table.
The period of a wave is the reciprocal of the frequency. ( '1' divided by the frequency)
T=Period F=frequency T=1/F Period=1/F
4. P'=P/a where Period of f(x) = P and period of f(ax) = P'
The f-block elements in period 7 are known as the actinides.
The equation that relates frequency (f) and period (T) is: f = 1/T or T = 1/f. This means that the frequency is the reciprocal of the period, and vice versa.
The period (T) and frequency (f) formula for a simple harmonic oscillator is: T 1 / f where T is the period in seconds and f is the frequency in hertz.
Br (Bromine) is a period 4 element in the same group as F.
The period of a wave can be directly calculated from the frequency of the wave. The period is the inverse of frequency (T = 1/f), where T is the period in seconds and f is the frequency in hertz.
Frequency (f) is the inverse of period (T), so the equation relating the two is: f = 1/T
The frequency is proportional to the reciprocal of the period and vice versa. Generally this proportion is 2*pi*f = 1/t and t = 1/(2*pi*f) where the frequency is f and the period is t.
The periods are the rows, and the groups are the columns, so Fluorine, F, is in Period 2 (and Group 7).
The halogen in the 2nd period is fluorine (F).
To determine the energy level of the f-orbital in a particular period, consider the principal quantum number (n) of the period. The energy level of the f-orbital follows the pattern 4n, where n is the principal quantum number. This means that for each period, the energy level of the f-orbital will be 4 times the principal quantum number of that period.
