Quantum mechanical model of atom

The atomic structure of matter is composed primarily of protons, electrons, and neutrons, which are the building blocks of matter.It is composed of protons and neutrons, which form the nucleus of the atom, which is surrounded by electrons that are also part of the atom.  The Atomic Theory of Dalton British chemist John Dalton proposed […]

Phosphorus is a chemical element with the symbol P and the atomic number 15. It is found in nature in small amounts. Elemental phosphorus comes in two major forms: white phosphorus and red phosphorus. However, due to the extreme reactivity of phosphorus, it is never found as a free element on the surface of the

The amount of matter present in an atom of an element is called its atomic mass. It is given as multiple of 1/12th of the mass of the carbon-12 atom, which has an atomic mass of 12 units.1 atomic mass unit is equal to 1.660539040 x10-24 grams on this scale.  The mass of an amu is about

Atomic Radius  A neutral atom’s atomic radius is the distance between its nucleus and its most stable electron. In practice, an atom’s diameter is measured and then split in half to obtain the result. The radii of neutral atoms range from 30 to 300 pm, or trillionths of a meter.The atomic radius is a measurement

A comparison of metals and nonmetals shows that the former has greater than nonmetals’ atomic radiuses, while the latter shows the former has smaller ones, as seen in the graph. The electron shells of atoms are so tiny that they resemble a cloud rather than a sphere, making it difficult to establish the atom’s size.

The atom is the building block of matter that occupies space and has mass. It is the basic unit that consists of protons (positively charged ions), neutrons (neutral) and electrons (negatively charged). The subatomic particles are distributed in the atom differently. The electronic configuration of the atom is the distribution of electrons around an atom.

It is called a crystal lattice because it is made up of ions that are tightly packed together in a repeating pattern. The idea of crystal packing is based on the assumption that the ions are hard spheres. The simplest way to visualize such an array is to arrange one layer of spheres on top

Crystals are made up of patterns that are three-dimensional in nature. These patterns are made up of atoms or groups of atoms that are arranged in an ordered and symmetrical manner and are repeated at regular intervals while maintaining the same orientation to one another. A crystal lattice is formed by substituting a representative point

Number of Atoms When it comes to elements, the atomic number of an element is determined by the number of protons present in it, and it is used to distinguish one element from the next. It is established by the number of protons and neutrons coupled that an element has a specific mass number. What

The atomic number and mass of each element are unique. Isobars are atoms with the same atomic number but various atomic masses, whereas isotopes are elements with different atomic numbers but the same atomic mass. In this article, we’ll look into isobars, their examples, applications, and some key questions. Isobars Isobar is a chemical element
