Concept introduction:
A periodic table is a tubular form of elements, which is arranged by the atomic numbers. Elements with similar properties appear in the same group in the periodic table. Most of the groups form chemical families. Family trends are most apparent among the main group elements.

- 3-58 In Section 2-3B, we saw that there are seven diatomic elements. (a) Draw Lewis structures for each of these diatomic elements. (b) Which diatomic elements are gases at room temperature? Which are liquids? Which are solids?arrow_forwardIn order for sulfur to be a neutral atom it must have how many electronsarrow_forwardWhich elements (Groups) of the periodic table provide the most unstable ions (anions)? Give the name of such elements according to the description of the periodic table.arrow_forward
- If a new element were discovered and it was found to form 1- ions, in which group would you place it in the periodic table?arrow_forwardConsider the following elements in their stable forms: Chlorine Fluorine Bromine Carbon Then for each of the following questions, enter the number listed (1-4) before the element, for elements that satisfy the criterion. Enter the number(s) in order with no separators. If none, type "none" or leave blank. (a) Which of these elements have allotropes? fill in the blank 2d8840092ffc02e_1 (b) Which of these elements exist as diatomic molecules? fill in the blank 2d8840092ffc02e_2 (c) Which of these elements exist as a metallic lattice?arrow_forward17 X This is a Lewis dot diagram: Which element is represented? phosphorus (P) chlorine (CI) boron (B) sulfur (S) 18 Which two elements have the same number of valence electron 19 The diagram represents a neutral atom of fluorine-19.arrow_forward
- What is the chemical formula for the compound formed between manganese(IV) and chlorine? chemical formula: What is the chemical formula for the compound formed between manganese(IV) and sulfur? chemical formula:arrow_forwardWhat is the difference between sulfuric acid and hydrosulfuric acid?arrow_forwardUse the periodic table and predict the number of electrons that will be lost or gained by the following elements as they change into simple ions. Write an equation using elemental symbols, ionic symbols, and electrons to represent each change. a.Mg b.silicon c.element 53 d.sulfurarrow_forward
- 1. Hydrogen is a Group I element and each hydrogen will contribute I valence electron. Carbon is a Group (Roman numeral) element and each carbon will contribute ___ (number) electrons. Every oxygen atom in a compound will contribute valence electrons. Chloromethane has the molecular formula . Its skeleton is and the number of valence electrons may be determined as follows. There are three hydrogen atoms, each of which contributes 1 valence electron; the single carbon contributes 4 electrons; and the single chlorine atom contributes 7 electrons, making a total of 14 . A convenient tabular form of this calculation isarrow_forward2-98 Explain how the ionization energy of atoms changes when proceeding down a group of the Periodic Table and explain why this change occurs.arrow_forward
