Elements - Chemistry | Socratic

An element is the simplest type of substance: one that is made up of identical atoms, such as hydrogen. Once a different type of atom is coined with the atoms in an element, a compound is created; like when oxygen is coined with hydrogen and water is formed. However, if the atoms themselves don’t bond but two different substances exist together, we can call them a mixture, such as water

Helium - Element information, properties and uses

Boron | 7440-42-8

Boron was discovered by Sir Humphry Davy and J.L. Gay-Lussac in 1808. It is a trivalent non-metallic element that occurs abundantly in the evaporite ores borax and ulexite. Boron is never found as a free element on Earth.

How to Do a Flame Test for Qualitative Analysis

The flame test is used to visually determine the identity of an unknown metal or metalloid ion based on the characteristic color the salt turns the flame of a Bunsen burner. The heat of the flame excites the electrons of the metals ions, causing them to emit visible light. Every element has a signature emission spectrum that can be used to differentiate between one element and another.


2008-9-24 · Boron is a nonmetallic element that is extremely hard, brittle and either crystalline or amorphous. It will scratch glass.
