195| ΑΣΦ
A rows 1, 4 =
?

Answer 1

To fill in the blanks in the Mass Number (A) column, we need to consider the total number of protons and neutrons in the atom.

Step-by-step explanation:

To fill in the blanks in the Mass Number (A) column, we need to consider the total number of protons and neutrons in the atom. The atomic number represents the number of protons, so we can determine the number of neutrons by subtracting the atomic number from the mass number. Let's look at the examples given:

For row 1, where the element is ΑΣΦ and the atomic number is unknown, we need to find the difference between the mass number and the known atomic number (rows 3 and 4). The mass number for row 3 is 195, and the atomic number is unknown. The mass number for row 4 is also unknown. Therefore, we can't determine the exact values for the A column.
