General Chemistry Unit 1 Questions and
Answers | Latest Update | 2024/2025 |
Already Passed
What is the significance of the atomic number in determining the identity of an element?


✔✔ The atomic number represents the number of protons in the nucleus of an atom, which

defines the element and its position on the periodic table.




How do isotopes of an element differ from one another?


✔✔ Isotopes of an element have the same number of protons but different numbers of neutrons,

resulting in different atomic masses.




What is the concept of atomic mass and how is it calculated?


✔✔ Atomic mass is the weighted average mass of the isotopes of an element, calculated based

on the relative abundance and mass of each isotope.




How does the arrangement of electrons in an atom relate to its electron configuration?


✔✔ The arrangement of electrons is described by the electron configuration, which specifies the

distribution of electrons among the atom's orbitals according to the Aufbau principle, Pauli

exclusion principle, and Hund's rule.

, What is the role of quantum numbers in describing the location and behavior of electrons in an

atom?


✔✔ Quantum numbers describe the properties of atomic orbitals and the electrons within them,

including the energy level, orbital shape, orientation, and spin.




How do you determine the number of valence electrons in an atom, and why are they important?


✔✔ Valence electrons are determined by the outermost electron shell of an atom. They are

important because they are involved in chemical bonding and reactions.




What is the difference between a molecule and a compound?


✔✔ A molecule is a group of atoms bonded together, while a compound is a substance

composed of two or more different elements chemically bonded in fixed proportions.




How does the concept of periodicity help in understanding the properties of elements?


✔✔ Periodicity refers to the recurring trends in element properties across different periods and

groups in the periodic table, helping to predict and explain the behavior of elements.
