Question

Explain the reaction for Sr → Sr⁽²⁺⁾.

1) gain of electrons
2) loss of electrons
3) gain of hydrogen atoms
4) loss of hydrogen atoms

Answer 1

The reaction Sr → Sr²⁺ represents the loss of electrons by the strontium atom.

Step-by-step explanation:

The reaction Sr → Sr2+ represents the loss of electrons by the strontium atom. This is because the strontium atom loses two electrons to form the Sr2+ ion.

1. Gain of electrons
2. Loss of electrons
3. Gain of hydrogen atoms
4. Loss of hydrogen atoms
