What are the properties of a sodium atom?
Sodium is an alkali metal located in the first group or column of the periodic table. The sodium atom has 11 electrons and 11 protons with one valence electron in the outer shell. Characteristics and Properties Sodium in its pure form is very reactive. It is a very soft metal that can be easily cut with a knife.
Is a sodium atom more stable than a sodium ion?
To achieve a stable electron configuration it has to lose this electron so that all the electron shells are complete. This shows that sodium ions are more stable than the sodium atom, else there would not be a release of heat during the reaction.
What is more stable a sodium ion or sodium atom?
• Sodium ion has obtained a stable electronic configuration by giving out one electron from the sodium atom. Therefore, sodium ion has one electron less than the sodium ion. • In other words, the valence shell/ last shell of sodium atom has only one electron. But in sodium ion the last shell has 8 electrons.
What is bigger a sodium atom or sodium ion?
Sodium atom is larger than sodium ion because sodium is a metal and it has a tendency to loose electron since sodium has one electron (valence electron) in its valence shell. So, according to octet rule it looses it's one valence electron to complete its octet and become stable.

What is the structure of sodium metal?
Sodium, Na The electronic configuration of Sodium is (Ne)(3s1). Its atomic radius is 0.190 nm and the (+1) ionic radius is 0.95 nm. In the solid state Sodium has a body-centered cubic crystal structure with a = 0.428 nm and a nearest neighbor distance of 0.371 nm.
How many atoms sodium have?
So... for the element of SODIUM, you already know that the atomic number tells you the number of electrons. That means there are 11 electrons in a sodium atom.
How many shells does sodium have?

Is sodium an atom or ion?
Sodium atom has 11 electrons. Sodium ion has 10 electrons as sodium atom loses one electron to form sodium ion. Only sodium atom react vigorously with water whereas sodium ion does not.
Can you eat pure sodium?
Sodium is a chemical element. It is very reactive, so it isn't found free in nature. In fact, it undergoes spontaneous combustion in water, so while sodium is essential for human nutrition, you wouldn't want to eat pure sodium.
Why sodium is a metal?
Sodium is a metal because it is a good conductor of electricity, malleable and ductile. It can lose electrons easily from the valence shell whereas carbon is a bad conductor of electricity, not lustrous or malleable. It does not lose electrons easily.
Is sodium a salt or metal?
Sodium is a chemical element having the atomic number 11 and chemical symbol “Na”. The atomic weight of sodium is about 22.98 amu. Sodium is a metal. The melting point is 97.79 °C and the boiling point is 882.8 °C.
Is sodium a simple molecular structure?

What is the structure of NaCl lattice?
NaCl has a cubic unit cell. It is best thought of as a face-centered cubic array of anions with an interpenetrating fcc cation lattice (or vice-versa). The cell looks the same whether you start with anions or cations on the corners. Each ion is 6-coordinate and has a local octahedral geometry.

What is the atomic number of sodium?
body-centered cubic (bcc) Sodium is a chemical element with the symbol Na (from Latin natrium) and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table. Its only stable isotope is 23 Na.
What are the elements that make up sodium?
Sodium forms alloys with many metals, such as potassium, calcium, lead, and the group 11 and 12 elements. Sodium and potassium form KNa 2 and NaK. NaK is 40–90% potassium and it is liquid at ambient temperature. It is an excellent thermal and electrical conductor. Sodium-calcium alloys are by-products of the electrolytic production of sodium from a binary salt mixture of NaCl-CaCl 2 and ternary mixture NaCl-CaCl 2 -BaCl 2. Calcium is only partially miscible with sodium. In a liquid state, sodium is completely miscible with lead. There are several methods to make sodium-lead alloys. One is to melt them together and another is to deposit sodium electrolytically on molten lead cathodes. NaPb 3, NaPb, Na 9 Pb 4, Na 5 Pb 2, and Na 15 Pb 4 are some of the known sodium-lead alloys. Sodium also forms alloys with gold (NaAu 2) and silver (NaAg 2 ). Group 12 metals ( zinc, cadmium and mercury) are known to make alloys with sodium. NaZn 13 and NaCd 2 are alloys of zinc and cadmium. Sodium and mercury form NaHg, NaHg 4, NaHg 2, Na 3 Hg 2, and Na 3 Hg.
How much sodium is needed for a human body?
The minimum physiological requirement for sodium is estimated to range from about 120 milligrams per day in newborns to 500 milligrams per day over the age of 10.
How to make sodium alloys?

NaPb 3, NaPb, Na 9 Pb 4, Na 5 Pb 2, and Na 15 Pb 4 are some of the known sodium-lead alloys. Sodium also forms alloys with gold (NaAu 2) and silver (NaAg 2 ).
What is the condition where water and sodium are lost in the ECF?
Isotonic loss of water and sodium from the ECF compartment decreases the size of that compartment in a condition called ECF hypovolemia .
How do you isolate sodium salts?
Because of the high solubility of its compounds, sodium salts are usually isolated as solids by evaporation or by precipitation with an organic anti solvent , such as ethanol; for example, only 0.35 g/L of sodium chloride will dissolve in ethanol. Crown ethers, like 15-crown-5, may be used as a phase-transfer catalyst.
How many isotopes of sodium are there?
Twenty isotopes of sodium are known, but only 23 Na is stable. 23 Na is created in the carbon-burning process in stars by fusing two carbon atoms together; this requires temperatures above 600 megakelvins and a star of at least three solar masses. Two radioactive, cosmogenic isotopes are the byproduct of cosmic ray spallation: 22 Na has a half-life of 2.6 years and 24 Na, a half-life of 15 hours; all other isotopes have a half-life of less than one minute. Two nuclear isomers have been discovered, the longer-lived one being 24m Na with a half-life of around 20.2 milliseconds. Acute neutron radiation, as from a nuclear criticality accident, converts some of the stable 23 Na in human blood to 24 Na; the neutron radiation dosage of a victim can be calculated by measuring the concentration of 24 Na relative to 23 Na.
