Aline has a slope of 1/4.what is a slope parallel to it? what slope is perpendicular?

The perpendicular slope will be -4.

Step-by-step explanation:

In order to find perpendicular slope, you first need to flip the fraction. So, 1/4 becomes 4/1 or 4. Then you negate it. So, 4 becomes -4.

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.
