From the list below, choose which groups are part of the periodic table
Nata [24]

The periodic table of the elements are describe the electronic configuration of the elements on which the properties of the elements depends. Among the given groups only metal, non-metal and semi-metal group are the part of periodic table. The metallic property depends upon the binding energy of the electrons with the nucleus. Thus the elements which have the valence electrons more near to the nucleus that is s-block elements are more metallic in nature. On the other hand the elements which have the valence electrons far from the nucleus are more non-metallic in nature like p-block elements. However the binding energy or the attraction of the outermost electrons to the nucleus depends not only its valence electrons position but also some other factors like shielding effect, effective nuclear charge etc.

The elements which are in between the metals and non-metals can be classified as semi-metals.

Although the conductivity of a material is an inherent property of the metals but sometime the nonmetals or semi-metals are also behave like a conductor due to presence of the other elements, thus it cannot be a p[property of the periodic table. Similarly acidity, flammable gases are not part of the periodic table.

How does the energy of an electron change when the electron moves closer to the nucleus?
tankabanditka [31]
It increases. B.

Close to the nucleus are high energy levels, because of the pull of the nucleus.  But farther away from the nucleus, the electrons there are of low energy level.

What is the mechanical advantage of a wedge that is 2 inches at its widest part and has sloped side with a length of ten inches?
Artist 52 [7]

Answer:

5

Explanation:

Given parameters:

Width of wedge  = 2inches

Length of sloped side  = 10inches

Unknown:

Mechanical advantage  = ?

Solution:

A wedge is a simple machine used to split devices into two. It is a simple chisel.

The input force is through the width and the output wok done is through the length of the slope.

         

Mechanical advantage is the ratio of the output force to the input force;

           M. A  = \frac{Output force}{Input force }

therefore;

              M.A  = \frac{10inches }{2 inches}  = 5

Mechanical advantage has no unit.

Consider the following set of ions: Al3+; Li+, Rb+, [(C4H9)4N+].
krok68 [10]

Hey there!:

a) Cations which are lowest size generally forms adopts more number of water molecules around it. Such kind of Cations forms largest hydrated ions. Among given cations, Li+ is smallest one and (C4H9)4N+ is largest one. So, Li+ ion forms largest hydrated ion.

b) Organic ligands or alkyl chains contained Cations are hydrophobic in nature due to its low polar nature. Among given (C₄H₉)4N⁺ cation is hydrophobic in nature.

c) Size of cation inversely proportional to the hydrated sphere or number of water molecules attached. So, in the given Cations  (C₄H₉)4N⁺ is largest cation which attaches fewest water molecules.

d) Charge on the cation makes it more electrostatic maker. But size is inversily proportional to electrostatic property. (C₄H₉)4N⁺ is electrostatic structure breaker.

e) Al⁺³ has highest charge. So it is most electrostatic structure maker.

Hope this helps!
