Fill in the blanks to complete the table. Symbol Ion Formed Number of Electrons in Ion Number of Protons in Ion Ca Ca²⁺ ______ ______ ______ Be²⁺ 2 ______ Se ______ ______ 34 In ______ ______ 49

Verified step by step guidance

1. Identify the atomic number of each element to determine the number of protons in the neutral atom. For example, calcium (Ca) has an atomic number of 20, so it has 20 protons.
2. For each ion, determine the number of electrons by considering the charge. A Ca²⁺ ion has lost 2 electrons, so it has 18 electrons (20 - 2).
3. For Be²⁺, the atomic number of Be is 4, so it has 4 protons. The ion has 2 electrons, indicating it has lost 2 electrons.
4. For Se, the atomic number is 34, so it has 34 protons. To find the ion formed, consider common oxidation states; Se typically forms Se^2- by gaining 2 electrons, resulting in 36 electrons.
5. For In, the atomic number is 49, so it has 49 protons. Determine the ion formed by considering common oxidation states; In typically forms In³⁺ by losing 3 electrons, resulting in 46 electrons.
