A particle that contains a protons, 10 neutrons and 10 electrons is
A
positive ion
B
neutral atom of a metal
C
neutral atom of a non-metal
D
negative ion
correct option: d
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
