Interpretation Introduction

Interpretation: The electron configuration of Sc element should be determined.

Concept Introduction: Arrangement of electrons in the orbitals of an atom in an increasing order of energy of the orbital is said to be the electron configuration.

Answer to Problem 1E

  Sc: [Ar]4s23d1

Explanation of Solution

The number of electrons present in an element in its neutral state is equal to the number of protons in that element and is said to be its atomic number, which is unique for every element. Arrangement of electrons in the orbitals of an atom in an increasing order of energy of the orbital is said to be the electron configuration.

Since, the atomic number of Sc is 21 so, the number of electrons in Sc is 21.

The electron configuration of Sc is:

  Sc: 1s22s22p63s23p64s23d1

  Sc: [Ar]4s23d1

Concept Introduction: Arrangement of electrons in the orbitals of an atom in an increasing order of energy of the orbital is said to be the electron configuration.

Answer to Problem 1E

  Ti: [Ar]4s23d2

Explanation of Solution

The number of electrons present in an element in its neutral state is equal to the number of protons in that element and is said to be its atomic number, which is unique for every element. Arrangement of electrons in the orbitals of an atom in an increasing order of energy of the orbital is said to be the electron configuration.

Since, the atomic number of Ti is 22 so, the number of electrons in Ti is 22.

The electron configuration of Ti is:

  Ti: 1s22s22p63s23p64s23d2Ti: [Ar]4s23d2

Interpretation Introduction

Interpretation: The electron configuration of Ru element should be determined.

Concept Introduction: Arrangement of electrons in the orbitals of an atom in an increasing order of energy of the orbital is said to be the electron configuration.

Answer to Problem 1E

  Ru: [Kr]5s14d7

Explanation of Solution

The number of electrons present in an element in its neutral state is equal to the number of protons in that element and is said to be its atomic number, which is unique for every element. Arrangement of electrons in the orbitals of an atom in an increasing order of energy of the orbital is said to be the electron configuration.

Since, the atomic number of Ru is 44 so, the number of electrons in Ru is 44.

The electron configuration of Ru is:

  Ru: 1s22s22p63s23p64s23d104p64d75s1Ru: [Kr]5s14d7
