13 how did demitri Mendeleev deal with elements that had not bee discovered
he ignored them placing them in the table and shifting others when they were discovered
he gave them names and properties and placed them in the table
he left blanks for them in his periodic table as he predicted they would be discovered
he created them in his lab and placed them in the table
14 which of the following elements have the properties similar to those of astatine
F,Br,I
Na,Mg,Al
Ar,S,P
F,Ar,Ne
15 what istrue of the ionic size of the elements in agroup as one moves from top to bottom in that group
ionic size increases from top to bottom within the group
ionic size stays the same within the group
ionic size does not vary in any predicitable way withni the group
ionic size decreases from top to bottom within the group
16 how many valance electrons are in the outermost shell of the halogens
8
4
1
7
17 which of the following ststements explains why alkali metals sre so highly reactive
alakali metals have 2 valance electrons
the outermost shell of an alkali metal is one electron away from being complete
alakali metals have 8 valance electrons
alkali metals have one valance electron
18chlorine needs one more electron to fill its outer shell what is the name of the group to which chlorine belongs
halogen
alkaline earth metals
alkali metal
noble gas
19 for the A groups (groups 1A to BA) how does the group number relate to the electron arrangement in atoms of the group
the group number is equal to the number of valance electrons
the group number is equal to the charge on the ions
the group number is eqaul to the block number of the sublevel
the group number is equal to the number of electrons in the element
20 what is the electron configuration of an electrically neutral alkali metal
