isoelectronic
It could be, if it is a regular stick arrow then no.
k^2 + k = k^2 + k k^2 x k = k^3
72 - k = 31 Therefore, k = 72 - 31 k = 41
k(k + 5)
Argon is isoelectronic with potassium, as both elements have the same number of electrons - 18 in total. However, the distribution of electrons in the electron shells differs between the two elements.
Kr
Potassium (K) is isoelectronic with argon because they both have 18 electrons.
The ions that are isoelectronic with Cl- are Ar and K+. These ions have the same number of electrons as Cl- (18 electrons) but a different number of protons.
No, it is not true. The k2 ion, also known as the potassium ion (K+), forms because potassium (K) loses one electron to achieve a stable electron configuration. It is not isoelectronic with chlorine (Cl-) which gains an electron to achieve stability in its ionic form.
Argon (Ar) typically forms a monatomic ion with a charge of +1.
The ion that carries two negative charges and is isoelectronic with K+ is O2-. Both ions have 18 electrons, but O2- has gained two electrons to achieve a full outer shell, giving it a total charge of -2.
Isodoetic ions with argon are K+, Cl-, Ca2+, and Sc3+, as they all have the same number of electrons as argon.
Neon is isoelectronic with the sodium ion.
Krypton is isoelectronic with a sulfur ion. Both have 18 electrons.
None. The Se2- ion is isoelectronic with Krypton.
Hydroxide and water are isoelectronic with fluoride as they have the same number of electrons.
