The melting point of sodium chloride is 801 0C.
What else can I help you with?
What happens to the melting point of the alkali metals as the atom increase in size?
As we move down the group, the melting point decreases.
How many electrons does a stable sodium atom have?
Sodium has 11 electrons.
What is the type of particle of sodium flouride?
Sodium fluoride contain 1 sodium atom and 1 fluorine atom.
If an electron is removed from a sodium atom the atom becomes a sodium ion?
Yes, the cation Na+.
What do you call the atom of an element of sodium?
The atom of an element of sodium is called a sodium atom. It consists of a nucleus containing 11 protons surrounded by a cloud of 11 electrons.
Is sodium a reactive atom?
Yes It's a soft metal, reactive and with a low melting point
Does caesium have higher or lower melting points than sodium and why?
The melting point of caesium will be greater because of random, temporary dipoles caused by moving electrons called London dispersion forces. The bigger the electron cloud of an atom, the greater chance there is for a temporary dipole to exist. Caesium atoms, with LDF happening more frequently, will be harder to drive apart, and the melting point is increased.
What happens to the melting point of the alkali metals as the atom increase in size?
As we move down the group, the melting point decreases.
What is the difference between iron atom and a sodium atom?
Iron and sodium atoms differ in their atomic number, mass, and chemical properties. Iron (Fe) has an atomic number of 26 and is a transition metal with a higher melting and boiling point compared to sodium (Na) which has an atomic number of 11 and is an alkali metal with a lower melting and boiling point. Additionally, iron can exist in multiple oxidation states, while sodium typically exists in a +1 oxidation state.
What are the relationships between the melting point and the atomic radius of an atom?
A relation doesn't exist.
What is the melting point temperature?
The temperature at which the solid melts, which remains constant until all of the substance is melted.
How many proton does an atom of sodium have?
The atom of sodium has got 11 protons.
Is sodium an atom?
No. It is an element. Although you can have one atom of sodium.
What is the difference between a sodium atom and a potassium atom?
Sodium and potassium are two different albeit similar elements. A neutral sodium atom has 11 protons, 11 electrons and typically 12 neutrons. It forms and ion with 10 electrons. It has an atomic radius of 186 picometers. Potassium has a large, heavier atom than sodium A neutral potassium atom has 19 protons, 19 electrons ans usually 20 neutrons. It forms an ion with 18 electrons. Potassium's atomic radius is 227 picometers. Additionally, potassium is somewhat more reactive than sodium and has a lower melting point.
How many atoms in sodium fluoride?
One atom of sodium and one atom of fluorine.
If an atom of sodium combines with an atom of fluorine what is the name of the new compound?
The compound formed when an atom of sodium combines with an atom of fluorine is called sodium fluoride.
Is a sodium atom is larger than a silicon atom?
No, a silicon atom is larger than a sodium atom. This is because silicon has more electrons and protons than sodium, leading to a larger atomic radius.
