the first inoization energy is 2372.3 kJ mol-1
there are 6.0221415 × 10^23 in a mole from avagadros number, devide the ionization energy for one mole by the number of atoms in a mole and you get the first ionization energy for one atom.
I'm assuming you're referring to the problem Na(g)+Cl(g) -> Na+(g)+Cl-(g)Since, ionization energy is basically the amount of energy it takes to dislodge one electron from a neutral atom, Cl has to dislodge one electron to stabilize NaThus,Na -> Na++e-
937 Kilojoules/mole
The energy required to remove more than one electron from atoms. After the first electron is removed, there is now a positive charge which is working against removing another electron. So successive ionization energies increase.
A mole of iron has more mass than a mole of helium, even though they contain the same number of atoms, because 1 atom of iron has a greater mass than 1 atom of helium. It is similar to why 1 dozen bricks has a greater mass than 1 dozen roses. There are 12 items in each case, but 1 brick has a greater mass than 1 rose.
631 kJ mol-1
Ionization energy is more commonly used to remove the topmost electron in the atom very important information if you are getting ready for a test.
Ionization energy is the energy needed to remove 1 mole of loosely bonded electrons from one mole of atoms or ions.
The first ionization energy for nitrogen is 1402 kilojoules/mole
First ionization energy
I'm assuming you're referring to the problem Na(g)+Cl(g) -> Na+(g)+Cl-(g)Since, ionization energy is basically the amount of energy it takes to dislodge one electron from a neutral atom, Cl has to dislodge one electron to stabilize NaThus,Na -> Na++e-
The weighted atomic mass of calcium is 40.1 g/mole and helium is 4.0 g/mole
ionization energy
937 Kilojoules/mole
Briefly, it is the energy required to completely remove a valence (outer shell) electron from its atom when forming an ionic bond.See related links below for more info
What is the root-mean-squared speed of the helium atom in one mole of an ideal gas at a pressure of 2.00 atmospheres and a temperature of 30 degrees C?
The energy required to remove more than one electron from atoms. After the first electron is removed, there is now a positive charge which is working against removing another electron. So successive ionization energies increase.
22.4 litres of helium will weigh 4 grams and will have 6.023 x 1023 atoms (1 mole)
