S2- Cl1- and Ca2 plus are all with Ar?

They have the same electron configuration as argon, which means they are isoelectronic with argon.


What does s2- Cl1- K1 and Ca2 have incommon with Ar?

They all have stable electron configurations, either full outer shells (Argon) or filled electron orbitals (Sodium, Chlorine, Potassium, Calcium). This stability makes them chemically unreactive or less likely to form compounds under normal conditions.


S2 Cl1 K1 plus and Ca2 plus are all with Ar?

Sodium (Na+) with 1 electron in its outer shell, chlorine (Cl-) with 1 extra electron, potassium (K+) with 1 electron removed, calcium (Ca2+) with 2 electrons removed, and argon (Ar) with a full outer shell of electrons.


How do you arrange in order of increasing size S2- Cl- K plus Ca2 plus now arrange them in order of increasing ionization energy what is the electron configuration of each?

Arranging in increasing size: Cl- < S2- < K+ < Ca2+. Arranging in increasing ionization energy: K+ < Ca2+ < Cl- < S2-. Electron configurations: Cl-: [Ne]3s^2 3p^6 S2-: [Ne]3s^2 3p^6 K+: [Ar]4s^1 Ca2+: [Ar]4s^2


What do an ion of Ca2 plus and an atom of Ar have in common?

Both calcium ion (Ca2+) and argon atom (Ar) have a full outer electron shell, making them stable and unreactive. This stable electron configuration is achieved by either gaining or losing electrons to attain a full valence shell.


What is the noble gas electron configuration of Ca2 plus?

calcium is normally [Ar] 4s2 if it is a 2+ ion, then it has lost 2 electrons so the configuration is just [Ar]


Does Ca2 have an identical electron configuration as anything else?

No, calcium (Ca) has a unique electron configuration due to its atomic number and position in the periodic table. Its electron arrangement is 1s2 2s2 2p6 3s2 3p6 4s2. While there are other elements with similar electron configurations, none are identical to calcium.


What is isoelectronic with Se-2?

Kr


How do you simplify a plus ar?

( a + ar ) = a ( 1 + r )


Does k2plus and ca have the same electronic configuration as argon?

No, potassium (K) in its K2+ cation form and calcium (Ca) have different electronic configurations than argon (Ar). Potassium has an electron configuration of [Ar] 4s1 and calcium has an electron configuration of [Ar] 4s2. In contrast, argon has an electron configuration of 1s2 2s2 2p6 3s2 3p6.


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.


Isoelectronic with Ar?

Species that are isoelectronic with Ar (argon) have the same number of electrons as Ar, which is 18 electrons. Examples include K+ (potassium ion), Ca2+ (calcium ion), and Cl- (chloride ion).
