if 9 electrons are present in an element
then the element is fluorine
and if it gains 1 electron it can attain neon's electronic configuration
then it can gain stability
but if u mean that if 9 electrons are present in valency shell, the valency will be also 1 only but +1 bcoz if it lose 1 electron , it gets octet configuration and gains stability
