Question

For CO, carbon monoxide, answer the following questions:

A. Order the atoms and ions of the molecule from largest to smallest.
B. Write the electronic configuration and in the periodic table indicate group, period, representative, transition or internal transition; metal or non-metal.
C. Based on the location in the periodic table of the elements that make up the molecule, predict which will have the second highest ionization energy.
D. Describe and explain, by what chemical bond carbon (C) binds with itself and what chemical bond binds carbon with oxygen

Answer 1

Part A.

1. Atoms become larger as we go down a column of the periodic table, and they become smaller as we go across a row of the table.
2. The negative ion is much larger than the atom from which it was formed.
3. Positive ions should be smaller than the atoms from which they are formed.

The atoms and the ions present in the molecule is C, C^-, O, O⁺. Therefore the order in terms of the size is
