A particle that contains 9 protons, 10 neutrons and 10 electrons is
positive ion
neutral atom of a metal
neutral atom of a non-metal
negative ion
Förklaring
protons = 9
neutrons = 10
electrons = 10
Electronic configuration = 2, 8
Ground state Electronic configuration=2, 7
It means that the atom has gained an electron thereby making it have a negative ion.
When an atom donates an electron, it becomes positively charged.
When an atom accepts an electron, it becomes negatively charged
