When rubidium, an alkali metal, group 1, reacts it loses one electron.
In phosphene it gain 4 electrons. Phosphate lose 4 electrons
Polonium will neither gain nor lose electron. it will prefer to form covalent compounds by sharing of electrons.
Acids lose hydrogen ions.
The term Rubidium oxide generally refers to 1 compound, but it can also be used to refer some other oxides. There can be more than 1 oxides of Rubidium : "The most common" Rubidium oxide = Rb2O Rubidium peroxide = Rb2O2 Rubidium dioxide(1-) or Rubidium superoxide = RbO2 Suboxides of Rubidium = Rb6O, Rb9O2
It gains
It can lose 1.
lose
1. Rubidium don't gain atoms ! 2. If you think to electrons rubidium loss one electron and becom a cation.
Lose
No. Atoms can gain and lose electrons but seldom gain or lose protons.
a closed system will not gain or lose mass
It doesn't lose or gain
They gain or lose electrons, while the atoms combine.
Neither lose nor gain.
