Answer:

Both electrons of Mg should be transferred to one O.

Explanation:

This is because metals like to lose electrons whereas non metals like to gain electrons in an ionic compound. MgO is an ionic compounds. So Magnesium being a metal in group 2 of periodic table, it wants to donate 2 electrons to get to the octet rule, so it donates its electrons and oxygen accepts them to fill its octet rule.

Answer B

Mg has a positive ionic charge because it hoped to loose its two electrons to make it stable or happy

O had a negative ionic charge bc it wants to gain electrons to make it stable or happy

therefore,

QA) O would not want/wouldn't use up the energy to transfer 6 of its electrons and Mg would accept O's electrons
Q3) goes against laws of chemistry
Q4) Mg can not gain 2 extra electrons unless it is a double molecule (which it is not) a

Three different sub-atomic particles are described below: Particle X: Uncharged Particle Y: Carries positive charge Particle Z:

bazaltina [42]

The statement which is true about the three sub atomic particles is

X is a neutron,Y is a protons and z is an electron

<u><em>Explanation</em></u>

Atom has three sub atomic particles,that is neutrons,protons and electrons.

Neutrons have no electric charge,protons are positively charged while electrons are negatively charged.
Both neutrons and proton are located in the nucleus while electrons are located outside the nucleus.
since electrons are located outside the nucleus they orbit around the nucleus.
