D. S-2
Electron configuration has to do with the number of electrons, so using a Periodic Table, it is easy to find this answer.
- For example, O-2 has 2 more electrons than usual, so move two spaces to the right, which is neon.
- For F- , it is the same way. Since it is a minus 1, move one space to the right, which is neon.
- For Al+3 there are 3 LESS electrons than usual so move back(to the right) 3 spaces, which is neon.
- For S-2 , the answer to your problem, has the same electron configuration as Argon.
- For Mg+2 there are 2 less electrons so moving back 2 spaces gives you neon.
Remember 'minus' means more electrons so for electron configurations you move forward on the Periodic table for ions with negative charge and backwards if the ion is positive.

What is the Coordination number?
Coordination number of an ion is the number of oppositely charged ions present around that ion as the neighbour ions , in that ionic crystal.
What are spectator ions in Na plus plus OH- plus Cl- H2O plus Na plus plus Cl?
Na+ and Cl- are spectator ions.
What are negative Electrolytes?
The negative ions are chloride, bicarbonate, and phosphate
In chemical notation Ca2 plus means what?
calcium ions that has lost electrons. It will give away electrons.
What is described by the terms body-centered cubic and face-centered cubic?
The arrangement of atoms or ions in a crystal.
Can negative ions have a noble gas electron configuration?
yes
Which metals forms ions with a noble gas electron configuration?
Alkali metals and alkaline earth metals will form ions (by losing 1 and 2 electrons respectively) with noble gas electron configuration.
Do ions have the same electron configuration as noble gases?
The stable ions of all the elements except the Transition metals, Actinide, and Lanthanide series (that is the d and f block elements) form stable ions that are isoelectronic to a nobel gas by gaining or losing electrons in order to achieve an s2 p6 stable octet. For example, sodium will lose one electron to have the same electron configuration as neon, while nitrogen will gain three electrons to become isoelectronic to neon.
Which ions has the same electron configuration of a noble gas ca or ci?
Cl- and Ca2+ has the electronic configuration of the noble gas, Ar, with 18 electrons.
What is the noble gas electron configuration of sodium fluoride?
In NaF, there exists Na+ and F- ions and with the electron configuration of [He]2s22p6 (for Na+) and [He]2s22p6 (for F-)
What is the noble gas electron configuration of sodium chloride?
In NaCl, there exists Na+ and Cl- ions and with the electron configuration of [He]2s22p6 (for Na+) and [Ne]3s23p6 (for Cl-)
When sodium and chlorine form and ionic bond both ions acquire the electron configuration of a?
Noble Gas
State the importance of the noble-gas electron configuration in the formation of ions?
Chemical properties depend on electron configuration. By either gaining or losing electrons, an atom changes its electron configuration and therefore its chemical properties also change.The atoms of an element will react to achieve a noble-gas configuration. The atoms will either gain or lose electrons to achieve such a configuration.
What ions does not have a noble gas electron configuration S 2 Sr 2 you Cs or Be 3?
Be3+ has only 2 valence electron and not 8.
What is a noble-gas electron configuration and what is an example of an ion that has this type of configuration?
A noble gas electronic configuration has an outer shell of ns2, np6. Examles of ions with this configuration are O2- [He], 2s2 2p6 (the neon configuartion) Cl- [Ne] 3s2 3p6 (the argon configuration)
How do metals form ions to achieve the stable gas configuration?
metals lose electrons to form ions so as to obtain noble gas configuration. for e.g. sodium(Na) has 11 electrons i.e. 1 electron in its valent (last) shell, to attain noble gas configuration sodium loses 1 electron which may be gained by a non-metal to stabilize itself.
What are the similarities between the noble gases and alkali metals?
There are no similarities. Noble gases (group 18 elements) have completely filled orbitals with stable electron configuration and are generally unreactive. Alkali metals (group 1 elements) have one valence electron. They are reactive. When these lose one electron, they form ions which has the electronic configuration of the nearest noble gas.
