An atom is the basic unit of matter that consists of a nucleus containing protons and neutrons, surrounded by electrons.
What are the three subatomic particles present in an atom?
The three subatomic particles present in an atom are protons, neutrons, and electrons.
What is the charge of a proton?
A proton carries a positive charge (+1).
What is the charge of an electron?
An electron carries a negative charge (-1).
What is the charge of a neutron?
A neutron carries no charge (0).
What is the atomic number of an atom?
The atomic number of an atom is the number of protons in its nucleus.
What is the mass number of an atom?
The mass number of an atom is the sum of its protons and neutrons.
What is an isotope?
An isotope is an atom of the same element that has a different number of neutrons.
What is the electron configuration of an atom?
The electron configuration of an atom is the arrangement of electrons in its atomic orbitals.
What are valence electrons?
Valence electrons are the electrons in the outermost energy level of an atom.
What is the Bohr model of the atom?
The Bohr model of the atom depicts electrons orbiting the nucleus in specific energy levels or shells.
What is the quantum mechanical model of the atom?
The quantum mechanical model describes electrons as both particles and waves, represented by atomic orbitals.
What is an energy level?
An energy level is a specific region around the nucleus where electrons are likely to be found. Each level can hold a specific number of electrons.
What is the principle of electron configuration?
The principle of electron configuration states that electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels.
What is the difference between a cation and an anion?
A cation is a positively charged ion formed by losing electrons, whereas an anion is a negatively charged ion formed by gaining electrons.
What is the significance of the periodic table in understanding the structure of atoms?
The periodic table organizes elements based on their atomic number and reveals patterns in the structure and properties of atoms.
