Why does the second ionization energy of Group 1 Elements greater than the first ionization energy of Group 1 Elements?
It takes more energy to knock off two electrons
What consists of two protons and neutrons and is positively charged?
An ionized helium nucleus, i.e a helium atom that has had been stripped of it's three electrons, to create a particle with a charge of +3. Such a particle is unlikely to occur in nature, because of the extremely high first and progressive ionization energies of helium arising from it's complete outer electron shell.
Why was Ni chosen as the chemical symbol for nickel?
From the direct English name 'Nitrogen'It starts with an 'n'. N2
What is the first ionization energy of barium?
All atoms have two electrons in the first energy orgital, except for hydrogen (only has one).
What is the third ionization energy for fluorine?
Second ionization energy of fluorine is the amount of energy needed to remove an electron from a unipositive fluorine atom (F+)to form F2+,in all the gaseous state
Write equations that show the process for the first two ionization energies of tin?
The first ionization of tin is given as , Sn becomes Sn+1 and 1 e- . The amount of energy released is 708.6 kJ/mol . The second ionization reaction is Sn+1 becomes Sn+2 and 1 e- with 1411.8 kJ/mol energy released.
Why do alkali metals have lower ionization energies than the alkali earth metals?
Alkali gases only have 1 electron needing to be removed to reach a stable noble gas configuration. Alkaline earths have two electrons. Alkali metals thus have the lower ionization energy of the two groups.

Calculating ionization energy AP chemistry?
This is my QustionListed below are ionization energies for removing successive electrons from various atoms of the third period. Which of the following lists corresponds to the ionization energies for phosphorus?a. 496 kJ, 4,560 kJ (I.E. for the first two electrons)b. 738 kJ, 1,450 kJ, 7,730 kJ (I.E. for the first three electrons)c. 578 kJ, 1,820 kJ, 2,750 kJ, 11,600 kJ (I.E. for the first four electrons)d. 786 kJ, 1,580 kJ, 3,230 kJ, 4,360 kJ, 16,100 kJ (I.E. for the first five electrons)e. 1,012 kJ, 1,900 kJ, 2,910 kJ, 4,960 kJ, 6,270 kJ (I.E. for the first five electrons)
Why do metals and non-metals usually form ionic compounds whereas two bonded non-metals are never ionic?
First an explanation in terms of ionization energy and electron affinity: Metals have low ionization energies and readily form ions. Non-metals have high electron affinities- so put them together and electron transfer is favourable. Two bonded non metals are generally covalent- their ionization energies are high. Now an explanation in terms of electronegativity (electronegativity is related to ionization energy and elctron affinity) metals have low electronegativity- non metals are comparativelly high. So electron transfer is likely. Just a cautionary word about compounds of non metals never being ionic-- what about PBr5- a binary compound of two non metals- in the solid state this has the structure PBr4+ Br-...bit of a cheat really as there is a polyatomic ion in there but it is ionic!
Alkali metal and alkaline earth metal have how many ionization energies?
Alkali metals (group 1 elements) have one valence electron. Hence have one ionization energy Alkaline earth metals (group 2 elements) have two valence electron. Hence have two ionization energy
What are the two energies?
There are no known "infinite energies" in our real Universe.
Is the ionization enthalpy of the first two elements of isotopes same?
Ionization enthalpy of isotopes should be theoretically the same.But the recorded values aren't equal..nobody knows why..
Does calcium have a lower first ionization energy level than sodium?
No. Calcium has TWO valence electrons, and Sodium has ONE. It is lot easier to take off one, than two you see. However, the second ionization energy of calcium IS however than the second ionization energy of Sodium. ;)
Why does the second ionization energy of Group 1 Elements greater than the first ionization energy of Group 1 Elements?
It takes more energy to knock off two electrons
What is the difference between 1st 2nd 3rd ionization energies?
The second ionization energy is always greater than the first because once you have pulled off the first electron, you are now trying to remove the second electron from a positively charge ion. Because of the electrostatic attraction between + and -, it is more difficult to pull an electron away from a positively charge ion than a neutral atom.
What consists of two protons and neutrons and is positively charged?
An ionized helium nucleus, i.e a helium atom that has had been stripped of it's three electrons, to create a particle with a charge of +3. Such a particle is unlikely to occur in nature, because of the extremely high first and progressive ionization energies of helium arising from it's complete outer electron shell.
