How many protons, neutrons, and electrons are in a neutral atom of sodium?
1 Answer
Explanation:
The subatomic particles (protons, neutrons and electrons) can be determined using some basic information from the periodic table.
The Atomic Number of an element is always equal to the number of protons. The Mass Number of an element is equal to the protons added to the neutrons.
Atomic Number Of Natural Elements
Sodium (Na) is a silver-white coloured metal that has the atomic number 11 in the periodic table. It is an Alkali Metal and is located in Group 1 of the periodic table. It has the symbol Na. In order to write the Na electron configuration we first need to know the number of electrons for the Na atom (there are 11 electrons). When we write the configuration we'll put all 11 electrons in orbitals around the nucleus of the Sodium atom. In writing the electron configuration for sodium the first two electrons will go in the 1s orbital. Name: Sodium Symbol: Na Atomic Number: 11 Atomic Mass: 22.98977 amu Melting Point: 97.72 °C (370.87 K, 207.9 °F) Boiling Point: 883 °C (1156 K, 1621 °F) Number of Protons/Electrons: 11 Number of Neutrons: 12 Classification: Alkali Metal Crystal Structure: Cubic Density @ 293 K: 0.971 g/cm 3 Color: silvery Atomic Structure.
The element Sodium has an atomic number of 11 and an average atomic mass of 22.98 which makes the mass number 23.
Therefore
Atomic Number Of Nacl
Atomic Number 11 Atomic Number 11 is belong to element of Sodium. Chemical symbol for Sodium is Na. Number of protons in Sodium is 11. Atomic weight of Sodium is 8 u or g/mol.
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. This atom will have 11 electrons.
