2. calcium has one more electron than potassium in its outer shell. how many electrons are likely to leave the calcium atom?
Answer
Explanation:
Step1: Determine the number of valence electrons in potassium
Potassium ((K)) is in Group 1 of the periodic table. Atoms in Group 1 have 1 valence electron.
Step2: Determine the number of valence electrons in calcium
Calcium ((Ca)) has one more electron in its outer shell than potassium. Since potassium has 1 valence electron, calcium has (1 + 1=2) valence electrons.
Step3: Consider the electron - loss tendency
Atoms tend to lose electrons to achieve a stable electron configuration (usually a noble - gas - like configuration). Calcium, with 2 valence electrons, will lose 2 electrons to form a (Ca^{2+}) ion (similar to the electron configuration of argon).
