name the following polymers name the following polymers name the following polymers name the following polymers name the following polymers name the following polymers name the following polymers name the following polymers 2.11 please ionic bonding. The Na and Clions have electron structures that are identieal to which two inert gases? The Periodic Table 29 With regard to electron configuration, what do all the elements in Group VIIA of the periodic table have in common? 210 To what group in the periodic table would an element with atomic number 114 belong? 2.11 Without consulting Figure 2.6 or Table 2.2, deter- muEY mine whether each of the following electron con- figurations is an inert gas, a halogen, an alkali metal, an alkaline earth metal, or a transition metal. Justify your choices (b) 132 2p 3 3p (e) 122p (d) 1 2s 2p 3Explanation / Answer
(2.9)
Group VII A is called the halogen family group. All the elements in this group have one thing in common, they all have same number of electrons (equal to 7) in their outermost shell.
(2.10)
Element with atomic number 114 will be placed in the group 14 (group IV A) of the periodic table.
(2.11)
(a) This is a transition element, because it has complete outer shell but incomplete inner shell.
(b) This is an inert gas, because it has 8 electrons in the outermost shell.
(c) This is a halogen, because it has 7 electrons in the outermost shell.
(d) This is alkaline earth metal because it has 2 electrons in the outermost shell.
(e) This is a transition element, because it has complete outer shell but incomplete inner shell.
(f) This is an alkali metal because it has 1 electron in the outermost shell.
Hope this helps !
