What is electronegativity? Arrange the members of each of the following setsof elements in order of increasing electronegativities?(1)B, Ga, Al, In (2)S, Na, Mg, Cl (3) P, N, Sb, Bi (4) S, Ba, F, Si 相关知识点: 试题来源: ...
electronegativity:即电负性,首先由莱纳斯·鲍林于1932年提出,它综合考虑了电离能和电子亲合能,以一组数值的相对大小表示元素原子在分子中对成键电子的吸引能力.元素电负性数值越大,原子在形成化学键时对成键电子的吸引力越强.两者有关,但不能等同.电子亲和能是可以具体测量的,单位是KJ/mol,电子亲和能最大的元素是氯...
Electronegativity is the degree to which an atom can attract bonding electrons to itself. The difference between electronegativity...

Electronegativity is a property of an atom within a molecule, rather than an inherent property of an atom by itself. Thus, electronegativity actually varies depending on an atom's environment. However, most of the time an atom displays similar behavior in different situations. Factors that affect...

Electronegativity is determined by the size of an atom and the number protons in the nucleus. Larger atoms (i.e., going down a group on the periodic... Learn more about this topic: Electronegativity | Definition, Periodic Trend & Example ...
Electron affinity is a truly quantifiable value that can be measured by specific scientific means after anelectron has attached itself to the atom.Electronegativity on the other hand cannot be measured by scientific means.It is a number derived from computations involving an atom’s characteristics in...
What is an electrovalent compound? Bond Polarity and the Nature of Bonds: A bond between two atoms can be characterized by the electronegativity difference ({eq}\Delta EN {/eq}) between them according to the following rules: Non-polar covalent bond: {eq}\Delta EN<0.5 {/eq} ...
An enzyme is a biological catalyst that always a protein. It accelerates the rate in the cell of a particular chemical reaction. The enzyme doesn't destroy during the reaction and may reuse them various times. There are several different types of enzyme molecules in a cell, each unique to ...
