I'm pretty sure it becomes an ion! If an atom gains a negative electron, it becomes an ion.
Answer:
Neon molecule does not exist.
Explanation:
Neon is denoted by Ne which is noble gas. According to the "Molecular Orbital Theory", only those molecules exist that have a positive bond order and molecules with no bond or negative bond order cannot exist.
Answer:
3.50 kg
Explanation:
Law of definite proportion: These law states that all pure samples of a particular chemical compound contains similar elements combined in the same proportion by mass.
From the law above,
First sample,
The ratio of fluorine and magnesium in the sample of magnesium fluoride is
0.764:1.19 = 1:1.6
mass of fluorine: mass of magnesium ≈ 1:1.6
Second sample,
mass of magnesium fluoride = 5.75 kg
mass of magnesium = 1.19(5.75)/(1.19+0.764)
mass of magnesium = 6.8425/1.954
mass of magnesium = 3.50 kg
Hence the second sample produced 3.50 kg of magnesium.
