Answer:
If an atom gains or loses an electron, it bacomes an ion. An atom that gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion
Explanation:
A lithium atom has 3 protons and 3 electrons. It can lose one of its electrons, making it an ion. It now has more positive protons than electrons so it has an overall positive charge. Therefore it is a positive ion.
A fluorine atom will tend to gain, rather than lose, an electron. By gaining a negative electron, it has an overall negative charge. It has become a negative ion.
60 I think bcz if there is 1&2 they differ 10 times
Answer : The concentration of solution in ppm is, 500 ppm
Solution : Given,
Mass of solute (glucose) = 0.125 g
Mas of solution = 250 g
Parts per million (ppm) : It is defined as the mass of a solute present in one million 
parts by the mass of the solution.
Formula used :
Now put all the given values in this formula, we get
Hence, the concentration of solution in ppm is, 500 ppm
