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 type of particle of sodium flouride?
Sodium fluoride contain 1 sodium atom and 1 fluorine atom.
How many electrons does a stable sodium atom have?
A stable sodium atom has 11 electrons.
How does sodium atom form an ion?
A sodium atom becomes a sodium ion, when a neutron is added to the nucleus.
If an electron is removed from a sodium atom the atom becomes a sodium ion?
Yes, the cation Na+.
Is sodium a reactive atom?
Yes It's a soft metal, reactive and with a low melting point
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.
When an ionic compound forms between sodium and bromine atoms what occurs?
One electron from each sodium atom is transferred to the outermost shell of a bromine atom, thereby forming a sodium cation and a bromide anion. If the transfer takes place at a temperature below the melting point of the salt sodium bromide, a solid product results, as the ions spontaneously migrate into their lowest energy positions in a crystal lattice of sodium bromide.
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.
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 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.
Is sodium atom is a isolated atom?
yes sodiom atom is an isolated one it is the atom of sodium sodium chloride is salt
Is sodium an atom?
No. It is an element. Although you can have one atom of sodium.
Is a sodium atom is larger than a silicon atom?
No. A cesium atom is larger both in terms of atomic mass and atomic radius.
A sodium ion differs from a sodium atom in that the sodium ion?
A sodium ion differs from a sodium atom in that the sodium ion has a missing electron electron. It has a positive charge, as opposed to the atom, which is neutral.
How many nuetrons in a sodium atom?
there are 11.99 neutrons in an atom of sodium
