the reactivity of these elements with non metals size
Cosmic Chemistry: An Elemental Question The Modern Periodic …
The chemical reactivity of these elements increases with size. Calcium, strontium, and barium react with water forming hydrogen and alkaline compounds. Magnesium reacts with steam to produce magnesium oxide. Common oxides of alkaline earth metals
LP: Periodic Trends: Reactivity - Mr. Young''s Teaching …
For non-metals the trend is that reactivity increases up and to the right. Non-metals that are up and to the right are closer to the noble gases and do a better job of attracting electrons to their nucleus because they don’t have as many energy levels, and therefore their electrons feel less shielding.
IB Chemistry notes: Reactivity
Do not confuse this order of reactivity with that of the metals - these are non-metals, their reactivity is in terms of oxidising power - i.e. chlorine is the best oxidising agent out of chlorine, bromine and iodine. 1. Chlorine will displace bromine from Cl 2 -Br
Metals and Non-metals Reactivity Series of Metals …
Reactivity of element decreases on moving from top to bottom in the given reactivity series. In the reactivity series, copper, gold, and silver are at the bottom and hence are least reactive. These metals are known as noble metals.
B, C, O, F, and N are p-block elements. What is the …
Answer: The order of reactivity will be F > O > N > C > B. Explanation: Reactivity of an element is defined as the tendency for it to gain or loose electrons easily. From the given elements, all are non-metals except boron. Boron is a metalloid and it does not attract or loose electrons easily.
Activity of Metals - Purdue University
The rate of this reaction increases as we go down this column, however, because these elements become more active as they become more metallic. Classifying Metals Based on Activity The metals are often divided into four classes on the basis of their activity, as shown in the table below.
Year 10 Science Chemistry CC13a Group 1 (The Alkali metals)
Non-metals. They all react with water to produce a metal hydroxide and hydrogen. The reactivity of the metals increases as you go down the group. This is because the atoms increase in size and so the outer electron is more easily removed in a reaction

These are the14 elements from 90 (Th, thorium) to 103 (Lr, lawrencium). The lanthanides and actinides fit between groups 3 and 4 and are set off below the main portion of the periodic table. 4.
Non Metals | Definition, Properties and Examples of Non …
Non Metals - There is no definition of a nonmetal. Generally, any element lacking or having a deficiency in the preponderance of metallic attributes can be considered as a nonmetal. Nonmetals are distributed into two groups reflecting their relative tendency to create
Ionization Energy of Chemical Elements - Periodic Table
Helps to understand reactivity of elements (especially metals, which lose electrons). In general, the ionization energy increases moving up a group and moving left to right across a period. Ionization energy is is related with electronegativity and electron affinity.
Reactivity and Electronegativity - Periodic Table Project
Metals: Reactivity increases as you go down the group. ** The farther to the left and down the periodic chart you go, the easier it is for electrons to be given or taken away, = higher reactivity. Non-Metals: Reactivity decreases as you go down the group.

Group 1 - The Alkali Metals
The Group 2 elements are all metals with a shiny, silvery-white color. General Reactivity The alkaline earth metals are high in the reactivity series of metals, but not as high as the alkali metals of Group 1. Occurrence and Extraction These elements are all found
Halogen Elements and Properties - ThoughtCo
7/11/2019· The word halogen means "salt-producing," because halogens react with metals to produce many important salts. In fact, halogens are so reactive that they do not occur as free elements in nature. Many, however, are common in coination with other elements Here is a look at the identity of these elements, their loion on the periodic table, and their common properties.
