Aluminum
Aluminum (Al) always forms a 3+ cation in its 3rd period of the periodic table.
Cesium is a cation, as it has a positive charge due to losing an electron.
The cation is the metal "Cu", otherwise known as the element Copper.
Oxygen is an element. It normally forms anions.
Silver
Gallium is a metallic element. It forms cations Ga3+ and Ga+
A single element cation and single element anion form a binary ionic compound, where one element is a metal and the other is a nonmetal. The metal forms the cation by losing electrons, while the nonmetal forms the anion by gaining electrons. Examples include NaCl (sodium chloride) and KBr (potassium bromide).
Silver is normally not a cation or an anion, it is an element. Once it becomes an ion however, it will become a CATION with a +1 charge (Ag^+).
No, iodine is not a cation. Iodine is a non-metal halogen element that typically forms an anion in chemical reactions by gaining an electron to achieve a stable electron configuration.
Strontium can be a neutral atom or a cation.
The third period element that forms a 3- ion is sulfur.
The element with 10 electrons when it forms a cation with a 1 plus charge is Neon (Ne). Neon has an atomic number of 10, which means it has 10 protons and 10 electrons. The cation is formed when an electron is removed from Neon, leaving it with 9 protons and 1 electron, giving it a 1+ charge. Neon's atomic number: 10 Neon's electrons when forming a cation: 10 Neon's protons when forming a cation: 9 Neon's charge when forming a cation: 1+
