Atoms that gain extra electrons become negatively charged. Its electron configuration is $$1s^2 2s^2 2p^6 3s^1$$. The free metal does not occur in â¦ Its only stable isotope is 23 Na. Each orbital can hold only two electrons. By removing an electron from this atom we get a positively charged Na + ion that has a net charge of +1. â¢ Sodium ion has a +1 charge whereas sodium atom is neutral. It will float on water. It is abundant in the sun and other stars. Or, we can write distribution of electrons in a sodium atom as 2, 8, 1. The distribution of electrons in the sodium atom is as follows: In the first orbit or K-shell = 2 electrons In the second orbit or L-shell = 8 electrons In the third orbit or M-shell = 1 electron. The nex six electrons will go in the 2p orbital. Chemistry Matter Elements. It will ignite spontaneously on water. Since 1s can only hold two electrons the next 2 electrons for sodium go in the 2s orbital. Sodium is a chemical element with the symbol Na (from Latin "natrium") and atomic number 11. The sodium atom contains 11 electrons, 11 protons, and 12 neutrons. A sodium atom, which has 11 electrons, has _____ electron(s) in its third energy level. 0 b. â¢ Sodium atom is very reactive; therefore, wonât find free in nature. Explanation: The mass number is the sum of the neutrons and protons in an atomâ¦ When we write the configuration we'll put all 11 electrons in orbitals around the nucleus of the Sodium atom. 2 Answers Kaisha May 11, 2017 Mass number= 23. This means that sodium atoms have 11 protons. $\ce{Na \rightarrow Na^{+} + e^{-}}$ The cation produced in this way, Na +, is called the sodium ion to distinguish it from the element. â¢ Because of the release of one electron, the sodium ion radius differs from the atomic radius. The chemical symbol for Sodium is Na. Atomic Number â Protons, Electrons and Neutrons in Sodium. Sodium, element number eleven, is the first element in the third period of the periodic table. It is a soft, silvery-white, highly reactive metal.Sodium is an alkali metal, being in group 1 of the periodic table. Sodium has 11 electrons â¦ Also, the orbitals have a specific order of filling, generally: However, there is some overlap (any chemistry textbook has the details). It exists as sodium ions in a compound. The atomic number of sodium is 11. Atoms are neutral; they contain the same number of protons as electrons. Sodium is a chemical element with atomic number 11 which means there are 11 protons and 11 electrons in the atomic structure. Sodium is a chemical element with atomic number 11 which means there are 11 protons in its nucleus.Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. Related Questions & Answers: 1 c. 2 d. 8 But in sodium ion the last shell has 8 electrons. Sodium is a soft, silvery-white, highly reactive metal. In writing the electron configuration for sodium the first two electrons will go in the 1s orbital. In a neutral sodium atom, the number of protons and electrons are equal. A neutral sodium atom is likely to achieve an octet in its outermost shell by losing its one valence electron. What is the mass number of sodium? A neutral sodium atom, for example, contains 11 protons and 11 electrons. a. Sodium chloride or salt (NaCl) Soda ash (Na 2 CO 3) Baking soda (NaHCO 3) Sodium hydroxide or caustic soda (NaOH) Sodium nitrate or Chilean saltpeter (NaNO 3) Sodium Borate or borax (Na 2 B 4 O 7) Interesting facts: It is found free in nature. The outermost shell of the sodium ion is the second electron shell, which has eight electrons in it. The resulting model of the atom is called the quantum model of the atom.
