For main group elements, the valence shell consists of the ns and np subshells in the outermost electron shell.In the case of transition and inner transition metals, the subshells involved can also be in an inner electron shell. The atoms of metal elements are characterized by the presence of valence electrons, which are electrons in the outer shell of an atom that are free to move about. The number of valence electrons increases from left to right in the periodic table. Pt is a metal, found in a “B” column of the periodic table (I know, IUPAC did away with A’s & B’s several years ago, but they are useful for students, so I still use them…). It is very ductile, meaning that it can be easily stretched into a wire. Electron configuration of Platinum is [Xe] 4f14 5d9 6s1. Electron Configuration Platinum atom has 78 protons and electrons; the number of neutrons is variable and depends on the atomic mass of the isotope (atomic mass of the isotope - atomic number = number of neutrons). Characteristics and Properties Under standard conditions platinum is a shiny, silvery metal. Valence shell. In most cases conductors have one or two (sometimes three) valence electrons. Find out about its chemical and physical properties, states, energy, electrons, oxidation and more. In the below periodic table you can see the trend of Valence Electrons. The number of valence electrons increases from left to right in the periodic table. Used by the pre-Columbian Indians of South America, platinum wasn't noticed by western scientists until 1735. While these are the most common valences, the real behavior of electrons is less simple.

Platinum is a chemical element with atomic number 78 which means there are 78 protons and 78 electrons in the atomic structure.The chemical symbol for Platinum is Pt. These electrons determine the number of bonds that the element can form. Accordingly, valence electrons directly influence how elements behave in a chemical reaction. For facts, physical properties, chemical properties, structure and atomic properties of the specific element, click on the element symbol in the below periodic table. The number of valence electrons in an atom is what makes a material able to conduct electricity. 14 ). For example, the element Lithium has 1 valence electron. Electrons per Energy Level: 2,8,18,32,24,8,2 Shell Model; ... Valence Electron Potential ( … Usually, transition metals such as platinum have 3 valence electrons. Chemistry Stack Exchange is a question and answer site for scientists, academics, teachers, and students in the field of chemistry. Comprehensive information for the element Plutonium - Pu is provided by this page including scores of properties, element names in many languages, most known nuclides and technical terms are linked to their definitions. The amount of electrons found on the outer shell of an element is known as the valence number. Platinum atoms have 78 electrons and 78 protons with 117 neutrons in the most abundant isotope. Metals that have ONE valence electron are copper, gold, platinum and silver. Transition metals and heavier elements are exceptions and are more stable when they have more electrons in their outer shell. Practice counting valence electrons for neutral atoms If you're seeing this message, it means we're having trouble loading external resources on our website. Platinum chloride (PtCl 2) Platinum hexafluoride (PtF 6) Platinum silicide (PtSi) Xenon hexafluoroplatinate [Xe(PtF6)] Interesting facts: It is the rarest of the precious metals. It is considered to be a precious metal along with silver and gold. In most cases conductors have one or two (sometimes three) valence electrons.
