Which noble gas atom has the same number electrons as a sulfide ion?
This noble gas is argon (Ar).
Is argon a ion?
Argon's an element.
Why is chlorine -1 ion and sulfur -2?
Chlorine needs only one additional electron to form an ion that is isoelectronic with an atom of the noble gas argon, while sulfur needs two additional electrons to form an ion that is isoelectronic with an atom of the noble gas argon. Ions that are isoelectronic with noble gas atoms are particular stable; therefore, their formation is favored.
Which element had the largest atom potassium or argon?
argon
What is the total number of electrons in a chloride ion?
chlorine atom has 17 electrons when it accepts one more it becomes chloride ion so chloride has total 18 electrons, isoelectronic with Argon.
A chloride ion has the same number of electrons as a neutral atom of?
argon
What particle has the same electron configuration as a potassium ion?
argon atom
A chloride ion (Cl-) has the same number of electrons as a neutral atom of -?
argon
A chloride ion has the same number of electrons as a neutral atom of what element?
argon
When chlorine gains an electron to become a chloride ion with a -1 charge it ends up with the same electron arrangement as argon. Why doesn't it become an argon atom?
It doesn't become an argon atom because it (Cl-) still has 17 protons, and an argon atom has to have 18 protons.
What element has eighteen electrons?
As a neutral atom (When it is not an ion) the element argon has eighteen electrons.
Which noble gas atom has the same number electrons as a sulfide ion?
This noble gas is argon (Ar).
Is argon a ion?
Argon's an element.
Why doesn't chlorine become an argon atom when it ends up with a noble gas electron configuration?
Because the number of protons in chlorine atom and chloride ion are the same (17 protons). The element argon has 18 protons.
Why is chlorine -1 ion and sulfur -2?
Chlorine needs only one additional electron to form an ion that is isoelectronic with an atom of the noble gas argon, while sulfur needs two additional electrons to form an ion that is isoelectronic with an atom of the noble gas argon. Ions that are isoelectronic with noble gas atoms are particular stable; therefore, their formation is favored.
What atom has the same number of electrons as in ion of calcium?
calcium forms Ca+2 ion having 18 electrons which are equal to the electrons of noble gas Argon.
Is Cl isoelectronic with a noble gas?
Not a neutral Cl atom but the chloride ion Cl- is isoelectronic with the noble gas argon.
