Chapter 11 review

how many dots would a dot diagram for selenium, one of the group 16 elements, have

6

use the periodic table to classify the elements potassium (k), bromine (Br), and argon according to how likely their atoms are to do the following: (a) loose electrons to form positive ions (B) gain electrons to form negative ions (c) neither gain nor lose electrons

A) Potassium is able to lose an electron, but only to form a positive ion B)Bromine is most likely to gain 1 electron to become stable and also become a negative ion C)Argon is already stable and is most likely to neither lose or gain electrons.

which is the correct electron dot diagram for boron, one of the group 13 elements

A.

which best describes an atom represented by this diagram

It is not likely to bond because it's already stable

describe the change that is shown in this illustration. how does this change affect the stability of the atom

Nitrogen was unstable at first but when the 3 electrons were added to it, it became stable.

Atoms lose, gain, or share electrons and become as chemically stable as

a noble gas

which would most likely be joined by an ionic bond

a positive metal ion and a negative nonmetal ion

what would make bromine, a group 17 element more similar to a noble gas

gaining one electron

which group of elements on the periodic table forms covalent compounds with other nonmetals

group 18

if an electron transfers from one atom to another atom, what type of bond will most likely form

ionic

what change would make an atom represented by the diagram have the same electron arrangement as a noble gas

losing two electrons
