Atomic weight 11 corresponds to the element sodium (Na), which has an atomic number of 11. In terms of energy levels, sodium has three main electron shells: the first shell can hold up to 2 electrons, the second can hold 8, and the third shell has 1 electron. This configuration reflects its position in the Periodic Table and contributes to its chemical properties, particularly its reactivity and tendency to lose that single outer electron to achieve a stable electron configuration.

What is the approximate mass of a neon-11 atom?
The approximate mass is 11. Technically you could express this in units of daltons as 11 Da (Daltons previously called amu, atomic mass unit, or as 11 (the dimensionless, relative atomic mass which chemists simply call atomic weight) .

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)
How many electrons are In the first orbit of a sodium atom?
A sodium atom has an atomic number of 11, meaning it has 11 electrons. The first orbit, or energy level, can hold a maximum of 2 electrons. Therefore, in a sodium atom, the first orbit contains 2 electrons.
Atomic number of sodium?
It weighs the same as the atomic weight of a bannana
How many does 23 have?
atomic weight - protons = neutrons, Na-23 has an atomic weight of 23 amu, and 11 protons so 23-11=12 neutrons
An element has of atomic number of 11 and atomic weight of 23 what is the number of neutrons in the nucleus of this atom?
23 - 11 = 12
How do you the get neutrons?
Neutrons in an atom Equation Atomic Weight - Atomic Number = The neutrons of an element Round for the final answer Example: Sodium (Na) Atomic Number: 11 Atomic Weight: 23 23-11= 12 neutrons so therefore sodium has 12 neutrons
What is the atomic weight of bromine?
The atomic mass of Boron (B) is 11 but to be more accurate, the atomic mass is 10.81.
What is the approximate mass of a neon-11 atom?
The approximate mass is 11. Technically you could express this in units of daltons as 11 Da (Daltons previously called amu, atomic mass unit, or as 11 (the dimensionless, relative atomic mass which chemists simply call atomic weight) .
An element has a atomic number of 11 and an atomic weight of 23 how many neutrons does each atom contain?
An element with an atomic number of 11 has 11 protons in its nucleus. To find the number of neutrons, subtract the atomic number from the atomic weight (23 - 11 = 12), so each atom contains 12 neutrons.
What is the atomic number of Na 23?
atomic weight - protons = neutrons, Na-23 has an atomic weight of 23 amu, and 11 protons so 23-11=12 neutrons
Is sodium a power?
No. Sodium is an element on the periodic table symbolized by Na and the atomic weight of 11.
How many electron levels does sodium 23 have?
Sodium-23 has three electron levels: the first energy level can hold up to 2 electrons, the second energy level can hold up to 8 electrons, and the third energy level can hold up to 8 electrons. Sodium has an atomic number of 11, so sodium-23 has 11 protons and 11 electrons in a neutral state.
What is the atomic mass of neon'?
The approximate mass is 11. Technically you could express this in units of daltons as 11 Da (Daltons previously called amu, Atomic Mass unit, or as 11 (the dimensionless, relative atomic mass which chemists simply call atomic weight) .
Where are these numbers found in the periodic table?
There are multiple numbers on the periodic table. The ones right under the abbreviations is the atomic weight of the atom. The number just above the abbreviation is the atomic number. Here is an example: Sodium 11= Atomic Number Na= Atom Abbreviation 22.99= Atomic weight
