why do the atoms in the top rows in the periodic table have higher electronegativity than atoms in lower rows?\no the electrons of those atoms are part of the nucleus.\no the electrons of those atoms are farther from the nucleus.\no the electrons are forming ions.\no the electrons of those atoms are closer to the nucleus.
Answer
Brief Explanations:
Electronegativity is the ability of an atom to attract electrons. In the periodic table, as we move down a group (from top - rows to lower - rows), the number of electron shells increases. Atoms in top rows have fewer electron shells, so their outermost electrons are closer to the nucleus. A closer distance to the nucleus means a stronger attraction for electrons, resulting in higher electronegativity.
Answer:
The electrons of those atoms are closer to the nucleus.
