Isotopes are chemical elements with same atomic number (Z), but different mass number (different number of neutrons).

Hydrogen is an element with atomic number 1. It has three isotopes:

1) protium (₁¹H), with mass number 1 (no neutrons).

2) deuterium (₁²H), with mass number 2 (one neutrons, n° = 2 -1, n° = 1).

3) tritium (₁³H), with mass number 3 (two neutrons, n° = 3 -1, n° = 2).

True or false: the smaller the difference between the average experimental value and the correct (true) value the greater the ac
mel-nik [20]

Answer:

True

Explanation:

The accuracy level is usually determined by the difference between the experimental and correct value. It is important to note that the smaller the difference between the average experimental value and the correct (true) value, the more accurate it is.

When the difference is large then it means the accuracy level is low and not up to the required standard.
