Krypton (Kr) is the neutral element with 36 electrons, but there are ions (elements that have lost or gained electrons) that can have 36 electrons as well. This includes arsenic, selenium, bromine, rubidium, strontium, yttrium, zirconium, niobium, molybdenum, technetium, ruthenium, rhodium, palladium, silver, cadmium, and indium.
The elements in period 4 of the periodic table are: potassium, calcium, scandium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, gallium, germanium, arsenic, selenium, bromine, krypton.
Bromine has a higher ionization energy than selenium because bromine has a smaller atomic radius and stronger nuclear charge, making it more difficult to remove an electron from the outer shell. Additionally, bromine's electron configuration (4s2 3d10 4p5) is more stable compared to selenium's (4s2 3d10 4p4), making it require more energy to remove an electron from bromine.

Group 1 (Nickel, Calcium, Bromine) are likely to have similar properties as they are all transition metals with varying degrees of reactivity. 2. Group 2 (Aluminum, Germanium, Antimony) are likely to have similar properties as they are all metalloids with varying physical and chemical properties. 3. Group 3 (Oxygen, Selenium, Tellurium) are likely to have similar properties as they are all nonmetals with increasing atomic numbers.
Se-Cl bonds
There is not one but there are two metalloids in Period 4 of the periodic table. They are germanium and arsenic. There is a link below to the Wikipedia post on the metalloids so you can have a look at them.
The elements in the fourth period of the periodic table include potassium, calcium, scandium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, gallium, germanium, arsenic, selenium, bromine, krypton.
Germanium bromide has a polar covalent bond because germanium is less electronegative than bromine. This results in an unequal sharing of electrons between the two atoms, making the molecule polar.
The element with the smallest atomic radius among Ge, Se, Br, and As is Arsenic (As). Atomic size generally decreases across a period from left to right, so the elements in this group progress in order of increasing atomic radius: Germanium (Ge) > Selenium (Se) > Bromine (Br) > Arsenic (As).

Chlorine and fluorine are more reactive compared to the elements listed, because they are both in group 17 of the periodic table and have a higher tendency to gain electrons to achieve a stable electron configuration.
No, Selenium has 6 valence electrons while Bromine has 7. You can determine this because on the periodic table, Selenium is in Group VI while Bromine is in group VII.
In 1649, Johann Schröder published two methods for preparing elemental Arsenic. So the answer is Arsenic. Yahoo anwers.com
Bromine, its as simple as its more to the RHS of the periodic table
Selenium and bromine can form an ionic bond, where selenium, a nonmetal, gains electrons to become a negative ion, and bromine, a halogen, loses electrons to become a positive ion.
