Curso de química desde 0 ✅ [COMPLETO Y REEDITADO]

Explanation of atoms having a nucleus and crust, with protons and neutrons in the nucleus. Description of how atoms work with positive and negative charges, forming chemical elements.

Definition of chemical elements as atoms of the same class, examples like hydrogen, uranium, plutonium, and silver. Mention of the periodic table grouping elements by families with similar characteristics.

Discussion on atoms forming molecules, including water molecules composed of oxygen atoms. Explanation of atomic structure with protons and electrons balancing charges.

Explanation of atomic number, neutron variations in isotopes like deuterium, and how charged atoms can form unions by gaining or losing electrons.

Definition of a mole as a unit of substance quantity, the arrangement of electrons in orbitals, and the Pauli exclusion principle for orbital electron capacity.

Explanation of quantum numbers (main, secondary, magnetic, spin) defining electron systems and their characteristics like energy, shape, orientation, and angular momentum.

Overview of the periodic table grouping elements based on properties and atomic number. Description of transition metals, noble gases, and electronic configurations of different groups.

Explanation of periodic properties like ionization potential, electronegativity, and metallic character. Description of atomic radius, shielding, and trends in ionization energy and electron affinity across the periodic table.

Definition and explanation of electronegativity, ionization energy, and electronic affinity as periodic properties. Description of trends in capturing electrons, retaining affinity, and attracting shared electrons.

Definition of metallic character as the similarity of an element with a metal, related to its tendency to lose electrons. Overview of metal, semi-metal, and non-metal properties on the periodic table.
