Atoms and elements are related in that elements consist of one specific kind of atom. This means that the atom is the base unit of an element. Atoms consists of a nucleus, which contains protons, neutrons and electrons that orbit around the nucleus.Continue Reading
Hydrogen is an element composed of atoms that have one proton and one electron. However, different isotopes of hydrogen have varying numbers of neutrons.
Different elements have different numbers of protons, which determines an element's atomic number. On the periodic table, the atomic number identifies the specific element and how many protons are in its nucleus. For example, carbon has six protons, so its atomic number is 6.
When two or more elements react chemically, they form a substance called a compound. Some examples of compounds are calcium carbonate (CaCO3) and sodium chloride (NaCl).Learn more about Atoms & Molecules
Ionic compounds are formed when electrons are transferred from one atom to another, while covalent compounds are formed when both atoms share their electrons, resulting in no loss or gain of electrons for either atom, according to HyperPhysics. The atoms of covalent bonds are bound more tightly and form more stable molecules when compared to the atoms of ionic bonds, which show attraction to other nearby atoms.Full Answer >
The molecule SiH4 can be described as having a tetrahedral molecular shape because the 4 H atoms have bonded at a 109.5 degree angle to the Si atom which sits at the center.Full Answer >
The structural formula of methanol is represented by one carbon atom bonded to one oxygen atom and three hydrogen atoms, with the oxygen atom bonded to another hydrogen atom. The carbon atom has zero lone pairs, while the oxygen atom has two lone pairs.Full Answer >
In chemistry, the term "neutral charge" is used to refer to an atom or collection of atoms that contains neither a positive nor negative charge. To have a neutral charge, the atom must have an equal number of protons and electrons.Full Answer >
