Respuesta :
The two elements that are more likely to lose 2 electrons, are calcium and gallium while the element that is more likely to lose 3 electrons is indium.
What is valence electron?
Valence electrons are any of the electrons in the outermost shell of an atom; capable of forming bonds with other atoms.
The number of valence electrons of an atom of element will determine the number of electrons that element can lose in a reaction with other atoms.
- Calcium is a chemical element in group 2 of the periodic table with an atomic number 20. It has 2 valence electrons.
- Gallium is a chemical element with atomic number 31. It has 3 valence electrons.
- Indium is a chemical element with an atomic number of 49 that has 3 valence electrons.
Therefore, the two elements that are more likely to lose 2 electrons, are calcium and gallium while the element that is more likely to lose 3 electrons is indium.
