Sep 05, 2019 · Alkali metals react with hydrogen giving ionic hydrides, in which hydrogen has an oxidation number equals − 1. 2Li sH 2 g → 2 LiH s lithium hydride. 2Na s . S – Block Elements. General Electronic configuration is ns 1-2; This block is situated at the extreme left of the periodic table and contains elements of group 1 and 2. Group I elements are known as alkali metals. Group II elements are known as Alkali earth metal. These elements are soft metals. They have low melting point and boiling point. The first two groups of the periodic table, the s-block metals: P-block elements include the last six element groups of the periodic table, excluding helium. The p-block elements include all of the nonmetals except for hydrogen and helium, the semimetals, and the post-transition metals.

Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.The chemical symbol for Hydrogen is H. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. Its monatomic form H is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. Point to the graph to see details, or click for full data on that element.

Ununennium, also known as eka-francium or element 119, is the hypothetical chemical element with symbol Uue and atomic number 119. Ununennium and Uue are the temporary systematic IUPAC name and symbol respectively, until its discovery is confirmed and a permanent name is decided upon. Francium and radium make up the s-block elements of the 7th period. Francium is a chemical element with symbol Fr and atomic number 87. It was formerly known as eka-caesium and actinium K. It is one of the two least electronegative elements, the other being caesium.

This is a list of chemical elements, sorted by atomic mass or most stable isotope and color coded according to type of element. Each element's atomic number, name, element symbol, and group and period numbers on the periodic table are given. The number in parenthesis gives the uncertainty in. May 17, 2014 · Here is a list of elements of the periodic table, their atomic numbers, and element symbols.The list is ordered by increasing atomic number, which is the number of protons in an atom of that element. Each element has a symbol, which is a one- or two-letter abbreviation of its name. Oct 24, 2019 · Here's a list of the chemical elements ordered by increasing atomic number.The names and element symbols are provided. Each element has a one- or two-letter symbol, which is an abbreviated form of its present or former name.The element number is its atomic number, which is the number of protons in each of its atoms. The s-block elements of the periodic table are those in which the last electron enters the outermost s-orbital. Two groups 1&2 belong to the s-block of the periodic table. Group 1: Lithium,sodium, potassium, rubidium,caesium and francium. They are.

Aug 20, 2018 · The element with atomic number 57 belongs to i s-block ii p-block 0 votes Comprehension given below is followed by some multiple choice. These elements are known as transition elements because their properties are in between the s-block elements and the p-block elements. But there are some elements like zinc, cadmium, and mercury which have always completely filled d orbitals, thus these elements are not considered as transition elements.
