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
