Why is the electronegativity of galilium higher than that of aluminum?
Gallium, and geranium for that matter, have higher electronegativity's than aluminum (and silicon) because of their d-block contraction. The 3d-electrons do not shield the increased nuclear charge on these elements in the fourth period after the first row of transition metals. This gives them an unusually small atomic radius and a higher electronegativity.
What is most electronegative calcium or gallium?
Gallium. Ga electronegativity 1.81; Calcium 1.00.
What is the electronegativity of gallium and how does it compare to other elements in the periodic table?
The electronegativity of gallium is 1.81. This value is lower than elements like oxygen and fluorine, which are more electronegative. Gallium's electronegativity is closer to elements like aluminum and indium in the periodic table.
Which element has a higher electronegativity than nitrogen?
There are two elements. They are Fluorine and Oxygen
Which element has a higher electronegativity value Rubidium or Iodine?
Iodine has a higher electronegativity value than rubidium. Electronegativity increases across a period from left to right on the periodic table, so iodine, being on the right side of rubidium, has a higher electronegativity value.

Which of aluminium gallium or germanium is the most reactive?
Among aluminium, gallium, and germanium, aluminium is the most reactive. It readily reacts with oxygen, forming a protective oxide layer that can inhibit further reactions. Gallium is less reactive than aluminium, while germanium, being a metalloid, has even lower reactivity. Thus, aluminium is the most reactive of the three elements.
Which element has a higher electronegativity than nitrogen?
There are two elements. They are Fluorine and Oxygen
What is related to gallium?
Gallium is in group13, (group III) it is more similar to indium than it is to the lighter members of the group, boron and aluminium. It forms two ions, Ga+ and Ga3+ like indium.
Which element has a higher electronegativity value Rubidium or Iodine?
Iodine has a higher electronegativity value than rubidium. Electronegativity increases across a period from left to right on the periodic table, so iodine, being on the right side of rubidium, has a higher electronegativity value.
Does aluminium have higher thermal capacity than water?
No, water has a higher specific heat capacity than aluminium. This means water can absorb and store more heat energy per unit mass compared to aluminium before its temperature increases.
Why is caesium more reactive than magnesium?
The electronegativity of caesium is higher.
Hydrogen over heated aluminium Nothing observed H over heated copper oxide Red glow spreads and leaves red powder that conducts electricity Why is H more or less active than Al or Cu?
The Pauling electronegativity of hydrogen is higher than the electronegativities of aluminium or copper.And copper is more reactive than aluminium.The red poweder obtained is copper as a metal.
Which element would you expect to have a higher electronegativity than nitrogen?
Electronegative charge increases across the periodic table to the right and up into the corner ( excepting the Nobel gasses ), so the two elements that would have higher electronegativity in that direction and in order. Oxygen and fluorine.
Is calcium more reactive than aluminium?
yes. because calcium is almost never found in nature due to its high reactivity with water, but we can find copper metal in nature.
