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 In 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 In 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 In should be determined.
Concept Introduction: Structural
(e)
Interpretation:
The larger atom among indium and iodine 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 largest ionization energy among indium and iodine 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.

- What additional information do we need to answer the question Which ion has the electron configuration 1s22s22p63s23p6 ?arrow_forwardWhich statement is true of the quantum mechanical model, but not of the Bohr model? a. Electrons orbit the nucleus in simple circular orbits, just like planets orbit the Sun. b. The exact path that an electron follows within an atom cannot be specified. c. The electron is attracted to the nucleus of the atom.arrow_forwardThe Bohr model works for only one electron species. Why do we discuss it in this text (what's good about it)?arrow_forward
- In the Bohr model of the hydrogen atom, the electron occupies distinct energy states. In one transition between energy states, an electron moves from n=1 to n=2. Is energy absorbed or emitted in the process? Does the electron move closer to or farther from the nucleus?arrow_forwarda Write the complete ground state electron configuration for the scandium (Z=21) atom. b Use a noble gas core to write the electron configuration of iron.arrow_forward
