Interpretation:

The true and false statements about the ions to be predicted

Concept Introduction:

Formation of ions:

Atom possesses equal number of protons and electrons and remains electrically neutral. By gaining (accepting electrons) or losing (donating electrons) one or more electrons, convert the neutral atom into a charged particle called IONS.

Cation: The loss of one or more electrons by a neutral atom leaves the atom positively charged called cation.

Anion: The gain of one or more electrons by a neutral atom leaves the neutral atom negatively charged called anion.

The symbolic representation of ions:

The electrons are reside in the principal quantum number ‘n’; by losing and gaining electron, reduces and increases in the electron count in the electronic configuration of the atom; for a cation adding positive charge as a superscript to the symbol of the element and for the anion adding negative charge as superscript to the symbol of the element.

Ionic charges of main group elements can be predicted using the group number and the octet rule:

For 1A and 2A metals: cation charge = group number.

For non-metals in groups 5A, 6A, and 7A: anion charge = 8 -(group number)

The carbon-nitrogen peptide bond is rigid, but rotation can take place about the bond between the nitrogen and α-carbon atoms and the bond between the α-carbon and the carbonyl carbon atom. These bond angles define the conformation of the peptide chain. Consider the Ramachandran plot shown to answer both questions.
