Two atoms interact with each other as shown by the equation. Complete the equation by filling in the missing parts.

The isotopic symbol of the missing part is

Explanation:

In a nuclear reaction, the total mass and total atomic number remains the same.

For the given fusion reaction:

Total mass on reactant side = total mass on product side

2 + 2 = A + 1

A = 3

Total atomic number on reactant side = total atomic number on product side

1 + 1 = Z

Z = 2

Hence, the isotopic symbol of the missing part is

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

the major pests we deal with are insects, weeds and fungal diseases. a pesticide is a product, whether organic or chemical, used to kill the target pest. there are other techniques gardeners should use that can prevent the severe infestations that make the use of pesticides necessary
