The ninth member of the lanthanide series, terbium is a fairly electropositive metal that reacts with water, evolving hydrogen gas. The chemical properties of the atom are determined by the number of protons, in fact, by number and arrangement of electrons. - 25861540 The chemical symbol for Technetium is Tc. The chemical symbol for Dysprosium is Dy. It is also sometimes considered the first element of the 6th-period transition metals and is traditionally counted among the rare earth elements. The chemical symbol for Titanium is Ti. The chemical symbol for Germanium is Ge. In a neutral atom, the number of protons is equal to the number of electrons. It connects the potential energy of the interaction of the nucleus and electrons, as well as the magnitude of repulsion between particles having an equal charge.

Use the element blocks of the periodic table to find the highest electron orbital. An atom of an element in a compound will have a positive oxidation state if it has had electrons removed. Zirconium is a lustrous, grey-white, strong transition metal that resembles hafnium and, to a lesser extent, titanium. Erbium is a silvery-white solid metal when artificially isolated, natural erbium is always found in chemical combination with other elements.

Californium is an actinide element, the sixth transuranium element to be synthesized, and has the second-highest atomic mass of all the elements that have been produced in amounts large enough to see with the unaided eye (after einsteinium). Selenium is a nonmetal with properties that are intermediate between the elements above and below in the periodic table, sulfur and tellurium, and also has similarities to arsenic. Neptunium is the first transuranic element. It is also the most corrosion-resistant metal, even at temperatures as high as 2000 °C. Carbon is one of the few elements known since antiquity. Tungsten is an intrinsically brittle and hard material, making it difficult to work. As the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
