What is the charge on all the ions of non-metals of Group VIIA?
What is the charge on all the ions of non-metals of Group VIIA?
Homework Answers
Ans. -1
group Vll(A) is the group 17 i.e. halogen group having elements like F, Cl, Br, I etc. have -1 charge as their last shell has 7 electron in it and it gains tis stability by accepting an electron resulting in charge of (-1).

Transition metals can be distinguished from main-group metals by the fact that transition metals have higher relative atomic weights than main-group metals. only the main-group mctals can form complex ions. main-group metals have only +1 or +2 oxidation states. transition metals have a greater tendency to form colored compounds than main- group metals. main-group metals have higher relative atomic weights than transition metals.

The Group 2A(2) elements are called alkaline earth metals because their oxides give (alkaline) solutions and melt at such temperatures that they remained as solids ("earths") in the alchemists fires. denser low for 2A metals than larger lower The melting and boiling points are much for the corresponding 1A metals. ences smaller oxidizing Compared to corresponding Group 1A(1) elements, Group 2A(2) elements have metallic bonding and atomic sizes which makes them harder and...

If there are some group I ions mixed in with group II ions together, 1. what would happen when you follow the procedures of adding thioacetamide and heat in boiling water bath? (HInt: check the Ksp of group I ions with sulfide) 2. How would you separate the two groups of ions and identify the ions qualitatively? (Hint: some procedures are in the manual for groups I and II)

How are variables charged metals
How are variable charge metals (metals that can have more than one charge) named and how is this different than naming constant charge metals?

Q1. The following species a)-c) all contain complex ions of transition metals, which you can assume take up an octahedral geometry. a) [RuCl3(H2O)3] b) [Ir(bpy)3]Cl3 ; bipy = 2,2'-bipyridine c) K2[Mo(NCS)6] For each species: i) draw all the possible isomers of the complex ions; ii) calculate the charge of the metal, and the dn configuration; iii) draw a diagram showing d orbital occupancy and, where high and low spin cases are possible, predict which will be favoured considering the spectrochemical...
