The element is sulfur with 16 electrons. It gains two electrons to form sulfide ion which has 18 electrons as that of argon.
The element with the electron configuration 1s2 2s2 2p6 3s2 3p6 is Argon, which has an atomic number of 18.
In the shorthand method for showing electron configuration, the noble gas preceding the element is used to indicate the core electrons (inner shell electrons), while the valence electrons are indicated by the remaining electron configuration. For example, the electron configuration of potassium (K) can be written as [Ar] 4s¹, where [Ar] represents the noble gas core configuration (argon's electron configuration).
Argon has the same electron configuration as N3. Both have 10 electrons with the electron configuration 1s2 2s2 2p6.
When the element oxygen gains two electrons, it becomes stable and achieves a full outer electron shell, resembling the noble gas argon. This process results in the formation of an oxide ion (O²⁻), which has a complete octet, similar to argon's electron configuration. Thus, oxygen's stability is enhanced through the acquisition of these additional electrons.
K+ and argon have the same electron configuration
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.
The electron configuration of argon is [Ne] 3s2 3p6, where [Ne] represents the electron configuration of neon. Argon has 18 electrons, with 2 electrons in the 3s orbital and 6 electrons in the 3p orbital.
When sulfur forms a negative ion, it gains two electrons to achieve a full outer electron shell, making it have the same electron configuration as argon.
The atomic number of argon is 18. So it has 18 electrons. Its electronic configuration is 2, 8, 8 or [Ne] 3s2 3p6
Calcium (Ca) has 20 electrons in its neutral state. To attain a noble gas electron configuration (like argon), calcium would need to lose 2 electrons to have the same electron configuration as argon, as argon has 18 electrons.
Sulfur needs to gain 2 electrons to have the electon configuration of Argon
Considering the normal calcium ion Ca2+ it has the same electronic configuration as the noble gas Argon.
The electron configuration for an argon atom is [Ne] 3s2 3p6, where [Ne] represents the electron configuration of neon. Argon has 18 electrons, and this configuration shows the distribution of these electrons in the different energy levels and orbitals.
The electron configuration for argon is 1s2 2s2 2p6 3s2 3p6. Argon has 18 electrons and is found in the noble gas group, which means it has a stable configuration.
The element with the electron configuration 1s2 2s2 2p6 3s2 3p6 is Argon, which has an atomic number of 18.
Argon has the same electron configuration as a potassium ion, as both species have 18 electrons with the electron configuration of [Ne]3s²3p⁶.
The element with the electron configuration of 1s22s22p63s23p6 is neon, which has atomic number 10 and is a noble gas.
