Answer:
Electronegativity increases across the period on a periodic table.
Explanation:
Electronegativity is the ability of an atom to attract electron to itself.
All elements on the periodic table combines in order to have a complete octet i.e they all want to be like the noble gases, group 0 elements.
This is what drives most atom to combine chemically. By so doing, they either lose or gain electrons.
Cl belongs to the 7th group on the periodic table. It is the second element in this halogen group. Most halogens are notable for their high electronegativity. They have 7 electrons in their outermost shell and would require just an electron to complete their octet.
This makes them highly reactive and combine readily with other elements.
The halogens have a strong attraction for valence electrons. The higher the electronegativity value, the stronger the attraction an atom has for valence electrons.
Most metals like Al and Na are electropositive and readily donates or lose electrons so as to have a complete octet.
Dimethyl amine is Base. The basic character of it is due to the presence of lone pair of electron on nitrogen atom. The strength of amines is basically due to the presence of alkyl group attached to nitrogen atom. These alkyl groups donates electron to nitrogen atom hence increasing electron density on nitrogen and increasing its basic character.
When dimethylamine ( Kb = 5.9 × 10⁻⁴) is reacted with water it abstracts proton from water molecule convertion it into Hydroxide Ion (i.e ⁻OH). The reaction is as follow,
(CH₃)₂N + H₂O → (CH₃)₂N⁺H + ⁻OH
It is 50. The answer is 50. 10x5=50 50x1=50
Answer:
hi!
Explanation:
Well, some things I would do is to know the Periodic Table font and back. Know they elements and their class and atomic number and weight. Know how many atoms make up each element and how many protons, neutrons, and elements are in each atom.
