### Reference Table | Atom | Atomic Number | Mass Number | |------|---------------|-------------| | 1 | 7 | 15 | | 2 | 11 | 22 | | 3 | 14 | 28 | | 4 | 15 | 30 | ### Question Based on information in the table above and in the periodic table of the elements, which statement about these atoms is accurate? - ○ Atom 3 and atom 4 have the same number of neutrons in their nuclei. - ○ Atom 1 and atom 4 gain stability when they each lose one electron. - ○ Atom 1 and atom 4 have similar chemical reactivities. - ○ Atom 2 and atom 3 differ by six neutrons in their nuclei. - ○ Atom 1 and atom 2 are isotopes of the same element. ### Explanation of the Table The table provides details about four different atoms, specifying their atomic numbers and mass numbers. The **atomic number** corresponds to the number of protons in an atom's nucleus, which also equals the number of electrons in a neutral atom. The **mass number** is the total number of protons and neutrons in an atom’s nucleus. To find the number of neutrons, subtract the atomic number from the mass number: \[ \text{Number of Neutrons} = \text{Mass Number} - \text{Atomic Number} \] - **Atom 1**: Neutrons = \(15 - 7 = 8\) - **Atom 2**: Neutrons = \(22 - 11 = 11\) - **Atom 3**: Neutrons = \(28 - 14 = 14\) - **Atom 4**: Neutrons = \(30 - 15 = 15\) Use this information along with periodic table data to evaluate the correctness of the statements provided.
