How does the radius of a positive and negative ion compare to a neutral atom?

Mathematics
1 answer:
Tanzania [10]3 years ago
4 0

A neutral atom contains equal amount of proton and electron.

A negative ion contains extra electrons hence there is additional outer shell so it is expected that the radius is bigger than that of a neutral atom.

While a positive ion contains less electron so there is less outer shell so the radius is smaller than that of a neutral atom.

 

Arranging the radius in increasing order:

<span>positive ion, neutral atom, negative ion</span>

What postulate can be used to prove the triangles are congruent?
Komok [63]
The HL Postulate

You know that the two hypotenuses are congruent and that the two triangles each contain a shared segment in the middle (so by the reflexive property they are congruent). You have two congruent hypotenuses and two congruent legs, so you can conclude congruency by HL.
