What atom has 11 protons 11 electrons and 12 neutrons?
An atom of a sodium has 11 protons, 11 electrons, 12 neutrons.
What has 11 protons and neutrons?
Sodium
Sodium has a mass number of 23amu. Since sodium has 11 protons, the number of neutrons must be 23 – 11 = 12 neutrons.
What is the atomic number and the mass number of an atom with 11 protons and 12 neutrons?
Example: A sodium atom contains 11 protons and 12 neutrons; its mass number is 23.
What element is the number 11?
Sodium – Element information, properties and uses | Periodic Table.
How many protons are found in an atom with an atomic number of 11?
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.
What is the electron configuration of an atom that has 11 protons?
Sodium has 11 protons (atomic number is 11) and has one valence electron. As the Bohr model diagram below shows, Sodium has 11 protons and 12 neutrons in the nucleus to make the mass number 23. The 11 electrons necessary to make Sodium neutral (protons = electrons) are arranged in a pattern of 2-8-1.
