noble gas: Any of the elements of group 18 of the periodic table, being monoatomic and (with very limited exceptions) inert. This may best be explained by the facts that the. Identify the four blocks of the periodic table. The nonmetal elements occupy the upper right-hand corner of the periodic table. 2. (2) (iii) explain why the other non-metal elements of period 3 have low melting points. In which shell are the valance electrons of the elements in period 2 found? Ans: The elements which have a tendency to gain electrons are known as non-metals. Explain why elements in a group have similar properties. The nonmetal element group is a subset of these elements. Describe the acid-base character of the oxides of the period 3 elements Na to Ar. (Total 3 marks) 40. Key Terms: group family period alkali metal alkaline earth metal halogen noble gas metal nonmetal semimetal valence electron abbreviated electron … therfore we can deduce that generally the non metals compared to the metals of the same period have larger atomic number, ionization energy, electron affinity , electonegativity 0 0 Gervald F These elements have similar chemical properties that differ from the elements considered metals. Q: Note down the non-metallic character trends in the periodic table. as the elements in period 2 of the periodic table are considered in succession from left to right, there is a decrease in atomic radius with increasing atomic number. The two non-metals that will from three covalent singe bond nitrogen from second period in {eq}N{H_3} {/eq} and Phosphorus is from third period in {eq}P{H_3} {/eq} and both are from group fifteen. The heavy orange zigzag line running diagonally from the upper left to the lower right through groups 13–16 in Figure \(\PageIndex{1}\) divides the elements into metals (in blue, below and to the left of the line) and nonmetals (in bronze, above and to the right of the line). period: A horizontal row in the periodic table, which signifies the total number of electron shells in an element’s atom. Non metals have s and p valence electrons, so they have 2 in s orbitals and up to 6 in p orbitals. 1. There are 17 nonmetals on the periodic table. The tendency to gain electrons increases on moving across a period due to an increase in the nuclear charge and decrease in the atomic size. Non-Metals In The Periodic Table. Period 1: H and He Period 2: C, N, O, F, Ne Period 3: P, S, Cl, Ar Period 4: Se, Br, Kr Period 5: I, Xe Period 6: Rn The only exception to this is atomic number 1, Hydrogen (H), which has a different location on the table. number of protons increases and the number of shells remains the same. The elements on the right, nitrogen, oxygen, fluorine and neon all have low melting points and are all non-metals. Nonmetals include the nonmetal group, the halogens, and the noble gases. Non-metals can be easily located on the Periodic Table because they are to the right of the line that looks like a stepping ladder. Metals, Nonmetals, and Semimetals. atomic radius: A measure of the size of an atom. In fact, apart from neon which exists as a monatomic gas (Ne (g)) at room temperature and pressure, the others are all diatomic gases, nitrogen gas (N 2(g)), oxygen gas (O 2(g)) and fluorine gas (F 2(g)). For sodium oxide and sulfur trioxide, write balanced equations to illustrate their acid-base character. (2) (Total 6 marks) 39.
