Using the integer tiles interactive, what steps do you need to do to evaluate the following expression?
Select two options.
-5(-2)
Help me pls. O Drag 5 sets of -2 tiles to the window.
Drag zero pairs to the window.
Remove the 5 groups of -2 tiles.
Remove 5 negative tiles from the window.

the answer will be

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.
