Question

A. An element with the valence electron configuration 4s2 would form a monatomic ion with a charge of In order to form this ion, the element will electron(s) from/into the subshell(s). B. If an element with the valence configuration 4s13d10 loses 1 electron(s), these electron(s) would be removed from the subshell(s).

Answer 1

Q we know that an element with the valence electron Configuration us would form a monoatomic con Ccq²+ ) with charge of +2 is Calcium (calle, element is ca. Electronic configuration of calcium (ca) - IS? 2s 2p6 35 3p6 45 Here valence electronic configuration of ca is us? and so in order to form cart on the element will loses two (2) electrons from the us subsuelus. Hence, An element with the Valence electron configuration 45² would form a monoatomic ion with a charge of [+2]. In order to form this con the element will loses two(2) electrons from the 145] subshel. B Electronic configuration of copper (cu) 15225zpl 352 3p6 45'3010 valence electron configuration of ca is us'adlo a Coppercay loses electron these would be removed from the 5 surshen and form cution.

Ĥ we know that a main group - elements are halosens having Valence electrons of seven (7) or the Valence electronic configuration of 35 3PS a halogens are in periodic group seventeen (17) and to complede electronic Configuration of inert gas Argon (187 acceat one electron and form mono- atomic ion with a charge of oil so. A main group element with the Valence electron configuration 35²3ps is in periodic group seventeen (177. st. Form a anonoatonis con with a charge of (3 valence electronic configuration of Potassium (K) is us' and form a monoatomic ion (kt) with charge of Al Potassium (K) is in periodic group t and an alkali metal. Electronic configuration of Potassium (K) as22s22pf 38² 386 45' A main group element with the Valence electron configuration is' is in periodic group 1 it forms a monoatomic ion with a charge of
