The correct answer is e) atom A becomes a positive ion and atom B becomes a negative ion. Ions are charged particles that result when a neutral atom gains or loses an electron.
Further Explanation:
In the problem, atom A loses an electron to atom B.
Suppose atom A has 11 protons and 11 electrons and atom B has 9 protons and 9 electrons.
BEFORE TRANSFER OF ELECTRONS
atom A: 11 protons, 11 electrons
atom B: 9 protons, 9 electrons
AFTER TRANSFER OF ELECTRONS
atom A: 11 protons, 10 electrons
atom B: 9 protons, 10 electrons
a) atom A becomes a negative ion and atom B becomes a positive ion FALSE because atom A has more protons than electrons turning it into a positive ion, and atom B now has more electrons making a negative ion.
b) atom A acquires more neutrons than atom B FALSE because only the number of electrons changed. The number of neutrons are unchanged in the formation of ions.
c) atom A becomes more negative than atom B FALSE because atom A becomes more positive since there is more protons (positively charged) than electrons (negatively charged) while atom B, with its extra electron becomes negatively charged
d) atom A acquires less neutrons than atom B FALSE because the number of neutrons does not change. Only an electron was transferred.
e) atom A becomes a positive ion and atom B becomes a negative ion TRUE because there are more protons than electrons in A after the electron transfer and there are more electrons in B than protons after receiving the electron.
