What is the atomic number of a sodium atom that has 11 protons and12 neutrons?
The atomic number of an atom is equal to the number of protons it contains, which in this case is 11. Sodium has an atomic number of 11, so the atom described is indeed a sodium atom.
Why would sodium never have 12 protons?
Sodium has an atomic number of 11, which indicates the number of protons in its nucleus. Thus, sodium would never have 12 protons since that would change its identity to argon, which has an atomic number of 18.
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.
How many protons in sodium?
the number of protons is the atomic number, which for sodium is 11. The number of electrons in neutral sodium atom is 11 and these are in the following shells:- 1st valence = 2 electron 2nd valence = 8 electrons 3th valence = 1 electrons
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 atomic nucleus contains 11 protons?
11. The atomic number of any atom equals the number of protons in the atom.
How do you find the number of protons in sodium 23?
To find the number of protons in sodium-23, refer to the atomic number of sodium from the periodic table. Sodium has an atomic number of 11, which tells you that it has 11 protons. Sodium-23 specifically refers to the total number of protons and neutrons in its nucleus, so it still has 11 protons.
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 is sodium atomic number?
The atomic number of sodium is 11. This means that sodium has 11 protons in its nucleus, giving it an atomic number of 11 on the periodic table. Sodium also has 11 electrons to balance the positive charge of the protons.
What is the atomic number of soduim?
Sodium (not soduim), Na, is atomic number 11, having 11 protons in nucleus
How many protons does one atom of element Sodium?
The atomic number of an element gives its number of protons per atom. Sodium's atomic number is 11. Thus, sodium has 11 protons per atom.
How many protons does sodium-21?
The amount of protons something has is equal to its atomic number. Sodium has 11 protons.
What is the atomic number of a sodium atom that has 11 protons and12 neutrons?
The atomic number of an atom is equal to the number of protons it contains, which in this case is 11. Sodium has an atomic number of 11, so the atom described is indeed a sodium atom.
Why would sodium never have 12 protons?
Sodium has an atomic number of 11, which indicates the number of protons in its nucleus. Thus, sodium would never have 12 protons since that would change its identity to argon, which has an atomic number of 18.
How many protons are in sodiun with a atomic number of 11?
There are always 11 protons in sodium. Every element has the same number of protons to their atomic number.
What is the atomic number and the mass number of an atom of an element with 11 protons and 12 neutrons?
Atomic number: 11 Mass number: 23 (11 protons + 12 neutrons) Atomic mass (aka atomic weight): 22.98976928 Element: Sodium (sodium-23 is the only stable sodium isotope)
