The elements in group-15 , 16 and 17 have 5,6 ad 7 valence electrons respectively , so they gain electrons to form anions.
Elements that will form anions are on the right side of the periodic table, except for the noble gases in group 18, which don't form ions.
Astatine is placed in group-17 in the Periodic Table. Its symbol is At.
Fermium (Fm) is in Group 7 in the Periodic Table.
Yttrium is in group 3 on the periodic table, also known as the scandium group.
Indium in the periodic table: group 13, period 5, atomic number 49.
Elements that will form anions are on the right side of the periodic table, except for the noble gases in group 18, which don't form ions.
anions are negatively charged species anions are not seen on the Periodic Table. however the elements on the right end of the periodic table (except for noble gases, group 18) have a strong tendency to accept electrons are become anions
An anion is a negatively charged ion that forms when an atom gains electrons. Anions are typically found on the right side of the periodic table among nonmetals.
Elements in Group 13 of the periodic table, also known as the Boron group, can form cations with a 3+ charge. This is because they can lose three electrons to achieve a stable electronic configuration. Key elements in this group include Boron, Aluminum, Gallium, and Indium.
An aion is a positively or negatively charged particle that forms when an atom gains or loses electrons. Aions are not found on the periodic table itself, but elements that commonly form aions can be identified by their position in the periodic table based on their electron configuration.
