Homework Answers
Li = lithium => no of electrons are 3 and it can removes
1 electron and remains 2 electrons and forms the nearest noble gas
configuration => He having 2 electrons
Mg = magnesium => no of electrons are 12 and it can removes 2 electron and remains 10 electrons and forms the nearest noble gas configuration => Ne having 10 electrons
O = oxygen => no of electrons are 8 and it can gains 2 electron and having the total 10 electrons and forms the nearest noble gas configuration => Ne having 10 electrons
P = phosphorous => no of electrons are 15 and it can gains 3 electron and having the total 18 electrons and forms the nearest noble gas configuration => Ar having 18 electrons
K = potassium => no of electrons are 19 and it can removes 1 electron and remains 18 electrons and forms the nearest noble gas configuration => Ar having 18 electrons
Se = selenium => no of electrons are 34 and it can gains 2 electron and having the total 36 electrons and forms the nearest noble gas configuration => Kr having 36 electrons
Sr = strontium => no of electrons are 38 and it can removes 2 electrons and remains 36 electrons and forms the nearest noble gas configuration => Kr having 36 electrons
answers =>
He => Li
Ne => Mg , O
Ar => P , K
Kr => Se , Sr

A Review Constants Periodic Table Learning Goal: To use electron configuration to explain magnetic behavior. Electron configuration The magnetic behavior of an atom or ion depends on its electron configuration. An important property that results from the electron configuration of an atom or an ion is behavior in the presence of an external magnetic field. Due to the random orientations of electron spins most materials have no permanent magnetic effect without an external magnetic field. Part A Select the correct...

Electron Configurations of lons ③ 19 01 23 Review Constants Periodic Table When an atom forms an ion, it will gain or lose electrons to attain a more stable electron configuration, frequently that of a noblo gas. Nonmetals tend to form anions by gaining electrons, which enter the lowest energy unoccupied orbital. Metais tend to form cations by losing electrons. Main group motals lose electrons in the reverso order of filling. Transition metals, however, lose s electrons first. Part A...
