An ion is an atom with a net electrical charge due to

Explanation:

Loss of one or more electrons by a neutral atom will help the neutral atom to acquire a positive charge.

For example, atomic number of sodium is 11 and to stabilize itself it needs to lose one electron. So, by losing an electron it will change into ion.

On the other hand, gain of one or more electrons by a neutral atom will help the neutral atom to acquire a negative charge.

For example, Cl has atomic number 17 and to fill its octet completely it need one more electron. So, by gaining an electron is will change into ion.

Therefore, we can conclude that an ion is an atom with a net electrical charge due to loss or gain of electrons.

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
