Element 16: Sulfur Sulfur S is an element that can never be overlooked. It was Mendeleev, who predicted undiscovered elements like eka-silicon as he found a gap between silicon and tin , today known as germanium, gallium, today called aluminum, and eka-boron, known as scandium. Oxygen, for example, has an atomic number of 8, an atomic weight of 15. The elements marked with an asterisk have no stable nuclides. Most of the elements are isotopes.

This list contains the 118 elements of chemistry. For example, any atom with an atomic number of 8 its nucleus contains 8 protons is an oxygen atom, and any atom with a different number of protons would be a different element. Every one of these elements is highly radioactive. Beryllium has one of the highest melting points among the light metals and is formed by the spallation of larger atomic nuclei that have collided with cosmic rays. This value will not change unless the nucleus decays or is bombarded nuclear physics. Group 1 consists of Alkali Metals — things like sodium, potassium, and cesium which are not as dense as other metals and are highly reactive. Elements in the periodic table are broken out into rows based on the number of shells they have.

Scientists created elements 93 through 118 in a laboratory. Along with atomic mass and atomic number values, this table helps us to understand the various properties, abbreviations, and names of all the elements present in nature. They are usually explained on the basis of electronegativity, ionization energy or the atomic radii etc. For example, element 120 has the temporary name unbinilium. In color, it is bright yellow, and it has an extremely bad odor like eggs gone bad.

You can quickly distinguish between metals and non-metals by looking at the table. Atoms are the fundamental building blocks of all matter and are composed of protons, neutrons, and electrons. I welcome you join the discussion! Metals are placed on the left-hand side and non-metals are placed at the right-hand side. The elements are arranged in order of increasing atomic number. Thus, each proton and neutron has a mass of about 1 amu. Phosphorus generally exists as white phosphorus and red phosphorus.
