Question

10 fill in the blank 1 point when comparing the coulombic attraction between gallium (ga) and aluminum (al), choose your answer... has a stronger force of attraction between the valence electrons and the protons in the nucleus. this is because choose your answer... s valence electrons are choose your answer... the protons in the nucleus.

Explanation:

Step1: Recall periodic - table trends

Atomic size increases down a group.

Step2: Analyze electron - nucleus distance

Aluminum is above gallium in Group 13. Gallium has more electron shells, but its effective nuclear charge on valence electrons is still significant due to poor shielding of inner electrons. And the valence electrons of gallium experience a stronger coulombic attraction because they are relatively closer to the nucleus compared to what would be expected just from the increase in shell number, as the nuclear charge has a stronger pull on them compared to aluminum's valence electrons.

Answer:

• First blank: Gallium (Ga)
• Second blank: Gallium (Ga)
• Third blank: closer to
