What is the sine value of π? -1/2 1/2 0 1

As we know that the value of trigonometric functions depends on the quadrant.

For example the value of sin in first quadrant is positive , in second quadrant its negative.

The value of sin, cos and tan can also be find using the trigonometric Table.

For the given problem, we can write from the trigonometric table that

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
