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...
Mass Number 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 mas...
What is the atomic mass of an atom that has 6 protons, 6 neutrons, and 6 electrons? What is the atomic mass of carbon? What is the melting point of sodium? What unit is used to measure weighted average atomic mass? How do you calculate atomic mass from atomic number?
11 An atom of one of the isotopes of sodium contains11 protons, 11 electrons and 13 neutrons.(a) Underline which of these three will be the same in neutral atoms of all isotopes of sodium. [2](b) State the nucleon number of this isotope...[1](c)What can you say about the chemica...
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...
Sodium is a metal. Firstly, from the periodic table we can see that sodium (Na) has an atomic number of 11 and is a member of ... 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...
Sodium definition, sources, properties (molar mass, valence electrons, atomic number, electron configuration), Bohr model, functions, toxicity, fun facts, price
Though table salt may be what comes to mind when you think 'sodium,' it is actually a compound, meaning it has more than one component. Table salt is sodium chloride, and is made up partly of sodium atoms and partly of chlorine atoms. ...
Sodium, one of many elements in the periodic table is being used in everyday life, it is also an essential element within your body. It is just another...
1 All of the atoms in alkali metals have one electron in their outer electron shells. To become stable they have to give off one electron to elements with seven electrons in their outer shell making it eight, also stable. Then they become single charged positive ions (cations). Melting ...
