Answer:
Check explanation.
Explanation:
Electron affinity simply means the ability of an atom to gain an electron. Electron affinity can also be defined as the change in energy of a neutral atom in the gaseous phase when an electron is added to the atom to form a negative ion.
Electron affinity characteristics trends is that it increases upward for the groups and from left to right across periods of a periodic chart.
Both Bromine and Iodine are both found in group 7/17 , that is the Halogens on the periodic chart. Group seven element has 7 valence electrons(that is, it remains 1 electron for them to reach their octet). Hence, when an electron is added to these Halogens, energy will be released.
WHAT CAUSES THE DIFFERENCES in ELECTRON AFFINITY for bromine and IODINE are;
(1). Atomic size: iodine atom is larger than a bromine atom. Therefore, outermost electrons of Iodine are located further away from the nucleus.
(2). The shielding effect: Iodine has an extra full shell of core electrons between the nucleus and the outermost shell and these extra core electrons will shield the outermost electrons from the nucleus.
So, less energy will be released when one mole of electrons is added to one mole of Iodine atoms as compare with Bromine atoms
Answer:
the particles with a negative charge are protons
