When this element gains 2 electrons it has the electron configuration of the noble gas Argon?
The element is sulfur with 16 electrons. It gains two electrons to form sulfide ion which has 18 electrons as that of argon.
What is the heaviest element of group 2?
It is about Cf element. it is in the !8th group.
What element has 2 valence electrons and more atomic mass than argon?
The element that has 2 valence electrons and an atomic mass greater than argon (which has an atomic mass of about 39.95 u) is calcium (Ca). Calcium is located in Group 2 of the periodic table and has an atomic mass of approximately 40.08 u. It is an alkaline earth metal and is known for its role in biological systems and materials like bone.
The element that forms a 2 plus ion with the same electronic configuration as Ar?
The element that forms a 2+ ion with the same electronic configuration as Ar is Calcium (Ca). When Calcium loses two electrons, it attains the same electronic configuration as argon by having a full outer shell of electrons.
Does element cl have a noble gas electronic configuration?
No, chlorine (Cl) does not have a noble gas electronic configuration. It has the electron configuration [Ne]3s^2 3p^5, which is one electron away from achieving a stable, noble gas configuration like argon (Ar).
Where does the element symbol for argon come from?
Ar, the first 2 letters of Argon. Am I missing something?
Which is the most unreactive element out of these 1. cheese 2. magnesium 3. francium 4. argon?
Argon is the most unreactive in this series. Cheese is not an element; it is a mixture of compounds.
What is the electronic configuration of an element with 18 atomic number?
The element is Argon. Its configuration is 2 8 8.
When this element gains 2 electrons it has the electron configuration of the noble gas Argon?
The element is sulfur with 16 electrons. It gains two electrons to form sulfide ion which has 18 electrons as that of argon.
What is the heaviest element of group 2?
It is about Cf element. it is in the !8th group.
What is Ar 4s2?
Ca
When full the innermost electron shell of argon contains how many electrons?
there are 2 completely full shells in argon. Argon= 18 electrons. 2 first shell 8 second shell (full) and 8 third shell (full)
What is the abbreviated electron configuration for argon?
The abbreviated electron configuration for argon is [Ne] 3s^2 3p^6. The [Ne] represents the electron configuration of the noble gas neon, which has the same electron configuration as the inner electrons of argon.
When was argon first discovered?
Argon was supposedly discovered in 1894 by 2 European chemists (William Ramsay a brit, and John Strutt, a scotsman)
What element has more valence electron that oxygen few valence electrons than neon more protons than sodium but fewer protons than argon?
The element described has more valence electrons than oxygen but fewer than neon, more protons than sodium but fewer than argon. This element is magnesium, which has 12 protons, 12 valence electrons (2 more than oxygen but 2 less than neon), and is situated between sodium and argon on the periodic table.
What is the third element in family 2 in the periodic table?
Calcium
What element has 10 electrons when it form an anion with a 2 negative charge.?
The element with 10 electrons in its neutral state is neon (atomic number 10). When it forms an anion with a 2- charge, it gains 2 electrons to have a total of 12 electrons, taking on the electron configuration of the noble gas, argon.
