Is Se2 an ion?
Similar to sulfide, in aqueous solution, the selenide ion, Se2−, is prevalent only in very basic conditions. In neutral conditions, hydrogen selenide ion, HSe−, is most common. In acid conditions, hydrogen selenide, H2Se, is formed. Some selenides are reactive to oxidation by air.
What is electron configuration for S2?
S: 1s2 2s2 2p6 3s2 3p4 S2- : 1s2 2s2 2p6 3s2 3p6 Note: Replacement of 1s2 2s2 2p6 by [Ne] is acceptable.
How do you find the amount of electrons in an ion?
The charge on the ion tells you the number of electrons. If the charge is positive, subtract that number from the atomic number to get the number of electrons. You have more protons. If the charge is negative, add the amount of charge to the atomic number to get the number of electrons.
What element has 53 protons and 74 neutrons?
Iodine has 53 protons and 74 neutrons. Its atomic mass is 127.
How many electrons are there in one sulfide ion?
It has 4 electrons in the 4p shell. Sulfide ion is formed at the lowest oxidation state that sulfur can achieve. Since losing 4 electrons requires a lot of energy sulfur will gain the 2 electrons in the 4p shell and will have a valency of -2.
What element has 2 electrons?
Group -2 elements have 2 valence electrons in their valence shell.These group elements are commonly called as Alkaline Earth metals. Some examples are Berrylium,Calcium,Strontium,Barium,Magnesium etc.
How many protons neutrons and electrons does s have?
The atomic number of Se is 34. For each selenium atom , there are 34 protons, 45 neutrons, 34 electrons.
