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...
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...
What is the atomic number of sodium?Atomic Structure:Atoms are the smallest particles that still maintain the properties of an element. Atoms have a core called a nucleus made of protons and neutrons. They also have a cloud of electrons that circulate the nucleus....
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 ...
This results in an increase in the number of protons and a decrease in the number of neutrons. 3. Analyze the Nucleon Count: - Sodium-24 has 11 protons and 13 neutrons (since 24−11=13). - After the decay, magnesium-24 has 12 protons and 12 neutrons (since 24−12=12). - The...
at rest. The protons and neutrons of the nucleus account for nearly all of the total mass of atoms, with electrons and nuclear binding energy making minor contributions. Thus, the numeric value of the atomic mass when expressed in the daltons has nearly the ...
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 is a white-silvery metal that belongs to Group 1 (alkali metals) and Period 3 elements in the periodic table. 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 ad...
