The atomic structure of a sodium atom (Na) consists of 11 protons and 12 neutrons in its nucleus, which is located at the center of the atom. Surrounding the nucleus are three energy levels (or shells) where electrons are located: the first energy level holds 2 electrons, the second holds 8 electrons, and the third holds 1 electron, giving sodium its characteristic reactivity. This single electron in the outermost shell makes sodium a highly reactive alkali metal.

What is the atomic number and atomic mass of Sodium?
The atomic number of Sodium is 11, which means it has 11 protons in its nucleus. The atomic mass of Sodium is approximately 23 amu (atomic mass units), which is the weighted average of all the isotopes of Sodium found in nature.
What has 11 protons?
An element that has 11 protons is sodium. Sodium has an atomic number of 11, which corresponds to the number of protons in its nucleus.
What Nucleus Structure of Sodium?
Sodium has 11 protons and usually 12 neutrons in its nucleus, giving it an atomic mass of 23 units. The nucleus of sodium can also have isotopes with different numbers of neutrons, such as sodium-22 and sodium-24.
What atomic nucleus contains 11 protons?
11. The atomic number of any atom equals the number of protons in the atom.
What is the atomic number of soduim?
Sodium (not soduim), Na, is atomic number 11, having 11 protons in nucleus
What atom has the largest atomic radius sodium or oxygen?
Sodium has a larger atomic radius than oxygen. This is because sodium has one more energy level (shell) of electrons compared to oxygen, leading to a greater distance between the nucleus and the outermost electron.
How many atomic number does a sodium atom have?
Sodium is a metal element. Atomic number of it is 1.
Which elements atomic nucleus contains 11 protons?
Sodium
What is the atomic number and atomic mass of Sodium?
The atomic number of Sodium is 11, which means it has 11 protons in its nucleus. The atomic mass of Sodium is approximately 23 amu (atomic mass units), which is the weighted average of all the isotopes of Sodium found in nature.
What is Na-23 atomic number?
The atomic number of Na-23 is 11. This means that sodium-23 has 11 protons in its nucleus.
What is the atomic number of sodium atom and sodium ion?
The atomic number of a sodium atom is 11, as it has 11 protons in its nucleus. When a sodium atom loses one electron to form a sodium ion, it becomes a Na+ ion which still retains the atomic number of 11, as the number of protons in the nucleus remains the same.
Atomic number for na?
The atomic number for sodium (Na) is 11. This means that sodium has 11 protons in its nucleus.
Why is the atomic number for sodium 11?
The atomic number is the number of protons in an atom of an element. For example, Sodium's atomic number is 11. This tells us that an atom of sodium has 11 protons in its nucleus. The interesting thing here is that every atom of sodium contains 11 protons. If an atom doesn't have 11 protons, it can't be an atom of sodium. Adding or removing protons from the nucleus of an atom creates a different element. For example, removing one proton from an atom of sodium creates an atom of neon.
Why is the atomic radius of sulfur is less than sodium?
The atomic radius of sulfur is less than sodium because sulfur has more protons in its nucleus, leading to a stronger attraction to its electrons, making the atomic size smaller. Sodium has fewer protons and a larger atomic radius due to weaker attraction between its nucleus and electrons.
