The statement which is true about <em>Atom A</em> and <em>Atom B</em> is; Choice B: <em>Atom B will give up electrons to form bonds.</em>
According to the question;
For Atom A:
- the electron configuration is; <em>1s²2s²2p³</em>
- Therefore, it has 5 valence electrons.
For atom B:
- the electron configuration is; <em>1s²2s²2p⁶3s²3p¹</em>
- Therefore, it has 3 valence electrons.
Since, electrons need 8 electrons to assume a full octet;
Consequently, Atom B will give up electrons to become stable.
