Is terbium an actinoid
WitrynaThe inner transition elements are two series of elements known as the lanthanoids (previously called lanthanides) and actinoids (previously called actinides ). They are usually shown below all the other elements in the standard view of the periodic table, but they really belong to periods 6 and 7. WitrynaActinoid dioxides and tetrafluorides can be prepared in a dry state by igniting the metal itself, or one of its other compounds, in an atmosphere of oxygen or of fluorine. Some tetrachlorides, bromides, and iodides are known for thorium, uranium, and neptunium. The ease with which they can be formed decreases with increasing atomic number.

WitrynaLithium is a metal that loses an outer electron and as a result will become positively charged. This is because by losing electrons it now has 2 electrons in its outer shell and 3 protons in its nucleus. Meaning there are more positive sub atomic particles than negative creating a positive charge. WitrynaWhich of the following is not an actinoid? A Curium (Z = 96) B Californium (Z = 98) C …
