Give the electron configuration and draw the orbital diagram for Co3+.  How many unpaired electrons are there?

Discuss the different property trends of the elements ( for example atomic and ionic radius, electronegativity, electrons affinity, ionization energy) in the periodic table and the driving force behind the trends?

The Lewis structure for a boron atom has electron pair(s) (represented by :) and unpaired electrons (represented by -). Assume that electrons fill in the same order as an orbital diagram. 1; 1 1; 3 0; 3 2; 1 O 3: 0

Write the condensed (noble-gas) electron configuration of Mg²⁺.

What is the orbital diagram for Nitrofen N 7

The electron configuration of indium is [Kr]5s²4d¹05p¹. How many electrons does a neutral atom of indium have? 49 How does this element complete its octet? Indium forms compounds with chlorine; one example is the formation of InCl (indium (I) chloride). What electron do you think indium gave up? Why?

How many electrons are located in the 4s orbital for Ca*2 cation? O 6 O 4 O 2 CO

1) Give the electronic configuration of Silver and Silver (2+). Note that Silver (2+) means that it has lost 2 of its valence electrons.

Group the electronic configurations of neutral elements in sets according to those you would expect to show similar chemical properties. 1s²2s²2p63s²3p6 1s²2s²2p²³: Set A 1s²2s²2p 3s²3pº: 1s²2s²2p³ 1s²2s²2p 3s ²3 pº 4s²3d¹⁰4p⁰: 1s²2s²2p 3s²3p³: Determine the chemical symbols for the neutral elements corresponding to the electronic configurations. Use proper formatting; letter case matters. Answer Bank 1s²2s²2p 3s²3 p4s²3d¹04p6 1s²2s²2p 3s²3p³ Set B
