Question
Choose the incorrect statement about the trends in the properties of the elements of a period going from left to right from the following statements.
- The oxides become more acidic.
- The elements become less metallic.
- The number of valence electrons increases.
- Atoms start to lose their electrons more easily.
Hint:
Electron affinity is an ability of an atom to accept an electron.
The correct answer is: Atoms start to lose their electrons more easily.
Electron affinity is the ability of an atom to accept an electron. Electron affinity increases from left to right within a period. This is caused by the decrease in atomic radius.
Hence, statement d is incorrect.
