Sodium/Atomic number
How many neutrons are there in sodium?
12 neutrons
1. Given the fact that there are 12 neutrons in sodium, the complete symbol for sodium is 2311Na.
How many protons electrons and neutrons are there in an atom of NA 21?
Sodium has 21 known isotopes. All of those isotopes would have 11 protons per sodium nucleus, and 11 electrons, in the neutral atom. The element sodium has 12 neutrons, 11 electrons and 11 protons.
Why does sodium have 11 protons and 12 neutrons?
This tells us that sodium has 11 protons and because it is neutral it has 11 electrons. The mass number of an element tells us the number of protons AND neutrons in an atom (the two particles that have a measurable mass). Since sodium has 11 protons, the number of neutrons must be 23 – 11 = 12 neutrons.
What is the atomic mass of sodium Na?
22.989769 u
Sodium/Atomic mass
Why does sodium have 11 protons?
We know that the atomic number of sodium is 11. This tells us that sodium has 11 protons and because it is neutral it has 11 electrons. The mass number of an element tells us the number of protons AND neutrons in an atom (the two particles that have a measurable mass).
What does 11 protons make?
Sodium 23
The 11 protons makes an atomic number of 11. Sodium 2311Na is the most common isotope of sodium.
Are you made up of 11 protons?
Mass number We know that the atomic number of sodium is 11. This tells us that sodium has 11 protons and because it is neutral it has 11 electrons. The mass number of an element tells us the number of protons AND neutrons in an atom (the two particles that have a measurable mass).
How many protons and neutrons does sodium have?
The element Sodium has an atomic number of 11 and an average atomic mass of 22.98 which makes the mass number 23. Therefore An atomic number of 11 means this atom will have 11 protons. A mass number of 23 means 23 – 11 this atom will have 12 neutrons. Since this atom is neutral the positive protons must be equal to the negative electrons.
How many electrons and neutrons does an atom have?
Its atomic number is 11 so it has 11 electrons and 11 protons. its mass number is 23. so it has 23-11=12 neutrons. The number of electrons of a NORMAL atom is equal to the number of protons. So we don’t need to care about the number of electrons , just proton and neutron is enough. Sodium has: p (protons) = 11 = e (electrons); n (neutrons) = 12
What are the two numbers for sodium on the periodic table?
Look for Sodium (Na) on your Periodic Table. There will be 2 numbers. The smaller is the number of protons in the nucleus. The larger is rhe atomic mass which is the total number of protons and neutrons in the nucleus. For a neutral atom the number of electrons is the same as the number of protons.
How many electrons and neutrons does 23 Na have?
Na). 23Na is the only stable (and the only primordial) isotope. 23 Na has 11 electrons and protons. And 12 neutrons…….
