Why is the ionisation energy of Nitrogen higher than Beryllium?
Wiki User
∙ 11y ago
Beryllium is a metal. It has 2 valance electrons (in the outer shell), and therefore it tends to lose those electrons in order to achieve a stable electron configuration, which in the case of beryllium is also 2 electrons, but in the inner shell. Nitrogen is a nonmetal, with 5 valence electrons, and it tends to acquire more electrons in order to reach a stable electron configuration of 8. Less energy is need to lose electrons when the result is going to be a stable electron configuration.

Why the first ionisation energy of potassium is only a little less than the ionisation energy of sodium?
both are in the same period which accounts for closeness. they are nonetheless different because there are more protons in the nucleus which means electrons are brought closer to it so there is a higher ionisation energy or potential
Does nitrogen have a higher bond energy than oxygen?
yes
How do you find out how many electrons are in the higher energy level of nitrogen?
Nitrogen has five electrons on the outer level.
Why does bromine have higher ionization energy then lead?
Bromine has less valence shells than lead making the distance between its valence electron and its nucleus less than that of lead. This means that there is greater attraction between the nucleus and electron for bromine and it requires a higher ionisation energy to remove its electron.
What is the rate of effusion of nitrogen compared to oxygen?
The rate of effusion for nitrogen is higher.

Does calcium have higher ionization energy than beryllium?
Calcium: 589,9 kJ/mol. Beryllium: 899,5 kJ/mol.
Why does helium has a higher first ionization energy than argon?
The ionisation energy depends on the orbital from which the electron is removed and also the distance of the orbital from the nucleus. In the case of Helium, the electron is removed from 1s orbital whereas in the case of argon it is from 3p orbital. As 1s is closer to the nucleus, the force of attraction experience by these electrons is higher and hence helium will have higher 1st ionisation energy.
Is ionisation enthalpy of potassium higher than that of sodium?
The ionisation enthalpy of potassium is lower than that of sodium.
Does nitrogen have a higher bond energy than oxygen?
yes
Elements with high ionisation energy have?
1.A small atomic/ionic radius 2.therefore less number of protons 3. more net nuclear attraction between the positively charged nucleus 4. higher energy is needed to break those bonds. 5. therefore an element has high ionisation energy
Why is the first ionization energy of boron lower than beryllium?
The rise in ionisation energy is not regular. To explain this we must remember that the second shell of electrons is actually subdivided into 2s and 2p. The most easily removed electron in Boron is that in the 2p orbital, higher in energy than the 2s electrons in Beryllium. It therefore needs less energy for total removal than does the 2s electron of Boron. This outweighs the effect of the increased nuclear charge of Boron, which tends to make its outer electron harder to remove.
How do you find out how many electrons are in the higher energy level of nitrogen?
Nitrogen has five electrons on the outer level.
Why is the ionization energy of oxygen less than that of nitrogen even if oxygen is to the right hand side of nitrogen?
half filled P orbitals increase the stability resulting in higher ionization energy
Why does bromine have higher ionization energy then lead?
Bromine has less valence shells than lead making the distance between its valence electron and its nucleus less than that of lead. This means that there is greater attraction between the nucleus and electron for bromine and it requires a higher ionisation energy to remove its electron.
Why nitrogen diffuses faster in high temperature?
Higher temperatures mean more heat energy which translates into more kinetic energy of the molecules of nitrogen gas. This greater kinetic energy allows the molecules to diffuse faster than at a lower temperature and lower kinetic energy.
Why does Ca have a higher ionization energy than Ga?
because it lower than Ba as you go down ionization energy increases
