Question

A radioisotope emits a positron to form titanium-48.
Express your answer as a nuclear equation.

Answer 1

\[_{Z}^{A}X \rightarrow~_{22}^{48}Ti + _{+1}^{0}e\]
what we have so far. Some isotype X with atomic number Z and mass number A emits a positron to form titanium 48.

to figure out what A, Z and X are, balance the equation. balance the top row of numbers to find A and the bottom row of numbers to find Z. once you have Z, look on the periodic table to see which element corresponds to atomic number Z.

an additional note: if your'e using an online program, it may use the symbol β for a positron instead of e.
