Concept Introduction:
The atomic number of an element is equal to the number of protons present in the nucleus of an atom which is unique for every element.
(b)
Interpretation:
The number of electrons in an atom of Te should be determined.
Concept Introduction:
The atomic number of an element is equal to the number of protons present in the nucleus of an atom which is unique for every element.
(c)
Interpretation:
The electronic configuration and abbreviated electron configuration of Te should be determined.
Concept Introduction:
The protons and neutrons of an atom are present in the nucleus of an atom whereas the electrons are always moving around the nucleus of an atom that is they possess kinetic energy. The lowest possible energy level of an electron in an atom is its ground state.
The electrons are arranged around the nucleus of an atom in an increasing order of energy levels and this description of orbitals of atom occupied by electrons is known as electronic configuration.
(d)
Interpretation:
The group number and the Lewis symbol for Te should be determined.
Concept Introduction:
Structural
(e)
Interpretation:
The smaller atom among selenium and tellurium should be determined.
Concept Introduction:
The distance from the center of the nucleus of an atom to the outermost electron is said to be the atomic radius of an atom.
(f)
Interpretation:
The atom having lower ionization energy among selenium and tellurium should be determined.
Concept Introduction:
The energy which is required to remove an electron from the gaseous state of an atom or ion is said to be the ionization energy.
