Answer:
<u>an element with a large number of valence electrons and a large atomic radius</u>
Explanation:
Electronegativity means a tedency when an atom attracts bonding electrons in a covalent bond situation.
» If an atom has many valency electrons [ <em>empty</em><em> </em><em>orbitals</em><em> </em><em>i</em><em>n</em><em> </em><em>o</em><em>u</em><em>t</em><em>e</em><em>r</em><em>m</em><em>o</em><em>s</em><em>t</em><em> </em><em>s</em><em>h</em><em>e</em><em>l</em><em>l</em><em> </em>], it has difficulty in attracting electrons hence electronegativity low.
» If an atom is large, its nuclear attraction force of incoming electrons is low hence low electronegativity.
Answer:
I think it's 8g
Explanation:
I think this is the answer
Answer:
first; why is it a question if teacher never teached you it LOL anyways..
Explanation:
i would say its the second one
"The smae quality of each element is present on both sides of the equation."
Answer:
Second order
Explanation:
Given that:
When the reaction A → B + C is studied, a plot 1/[A]t vs. time gives a straight line with a positive slope.
From the integration method for the second order of reaction.
Suppose that:
rate = k₂[A]²
∴
Therefore, a plot of the linear function versus t will be linear with a positive slope k₂ and the intercept on the concentration axis will be
The linear plot for a second order reaction can be seen in theimage attached below.
There are usually 3 topics used to compare types of radiation:
Ionising ability
Penetrative power
Range in air
Ionising ability
Alpha radiation has strong ionising ability, while beta only has moderate ionisation and gamma is very weakly ionising.
Penetrative power
Alpha particles are weakly penetrating, stopped by paper, while beta particles have stronger penetrating ability, stopped by skin and gamma radiation is very strongly penetrating, stopped only by thick layers of lead.
Range in air
Alpha particles- range of only a few centimetres
Beta - range of up to one meter
Gamma- infinite range in air.
Hope this helps:)
