An element is a pure substance made up of only one type of atom (the simplest unit of an element comprises sub-atomic particles: electrons, protons, and neutrons). In addition, an element cannot be decomposed by any chemical reaction into simpler substances. Group 1 elements, also known as...
Atomic Number: The atomic number of an element defines it and is equal to the number of protons in the nucleus. Protons: Protons are positively charged subatomic particles that make up the nucleus. Neutrons: Neutrons are neutrally charged subatomic particles that along with protons, make up the...
Mar 8,2024 How many neutrons, protons and electrons does a sodium atom have? A neutron is a neutral subatomic particle that, in conjunction with protons, makes up the nucleus of every atom except ordinar... Mar 6,2024
We can also include the subatomic constituents (protons, neutrons, and electrons), the bonding type, and the physical and chemical properties.Answer and Explanation: Sodium is an element made of sodium atoms in metallic bonding. Each atom has 11 protons (i.e. the atomic number) and neutral...
He named the new metal sodium, because he had used caustic soda or, more simply, soda, as his source of the element.(2),(3) In Germany caustic soda was known as natronlauge and L. W. Gilbert suggested the new element should be called natronium. ...
The sum of the number of protons and neutrons of an atomic nucleus. In other words, it's the sum of the number of nucleons in an atom. Relative Atomic Mass The ratio of the average mass per atom of an isotope to 1/12 the mass of a carbon-12 atom. Relative atomic mass is also ...
