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)
What is the atomic number of soduim?
Sodium (not soduim), Na, is atomic number 11, having 11 protons in nucleus
What is the Atomic number of Sodium-23?
Mass number is the number of protons and neutrons in the nucleus of an atom. Atomic number on the periodic table is the number of protons in the nucleus of an atom. mass number - atomic number = number of neutrons The atomic number of sodium is 11. Specified mass number is 23. Therefore, 23-11 = 12 neutrons
What is a mass number of an atom that has 12 netrons and 11 protones?
An atom of atomic number 12and mass number 22 contains how many protons?
What is the atomic number of an atom of an element with 5 protons and 6 electrons?
Disregard the electrons, as their relative mass is insignificant to that of protons and neutrons. To find atomic mass, add the numbers of protons and neutrons: 5 + 6 = 11 is the mass number.
Which elements atomic nucleus contains 11 protons?
Sodium
What does the nucleus of each sodium atom contain?
For sure the sodium atomic nucleus contains 11 protons. The natural isotope of sodium(23) also contains 12 neutrons, but other isotopes are possible with less or more of them in the nucleus. Still 11 protons, always!
What is the atomic number of an atom that has 11 protons in the nucleus?
Atomic number = number of proton in an atom Thus atomic number of an atom with 11 protons is 11.
If an atom contains 11 protons and12 neutrons its atomic number is?
It has 11 protons, so its atomic no. is 11. It is Sodium.
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)
If element Q has 11 protons its atomic what is 11?
If an element has 11 protons, its atomic number is 11.
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.
The number of protons in the nucleus of an atom is the of that atom?
Atomic number = number of proton in an atom Thus atomic number of an atom with 11 protons is 11.
What is the atomic number of soduim?
Sodium (not soduim), Na, is atomic number 11, having 11 protons in nucleus
How many protons are in Na22?
The atomic number o Sodium (Na) is 11. This means that the number of protons in the nucleus is 11.
What is the Atomic number of Sodium-23?
Mass number is the number of protons and neutrons in the nucleus of an atom. Atomic number on the periodic table is the number of protons in the nucleus of an atom. mass number - atomic number = number of neutrons The atomic number of sodium is 11. Specified mass number is 23. Therefore, 23-11 = 12 neutrons
How many electrons is there in boron if there is a atomic number or 5 and atomic mass of 11?
All you need is the atomic number, which gives the number of protons, in this case, 5. In any neutral atom the number of electrons is the same as the number of protons. So any neutral boron atom will have 5 electrons.
