an element e combines with oxygen to form an oxide EO2 which is a good conductor of electricity.answer the following
1)how many electrons will be present in the outer most shell of E
2)write the formulaof the compound formed when it combines with Chlorine
2) E has 4 valence electrons, so it need 4 more electrons to complete its octet. Chlorine atom has 7 valence electrons, so it needs one more electron to achieve noble gas configuration. Thus E atom will share its four valence electrons with four chlorine atoms to form ECl4 molecule .
