Answer:

Yes

Explanation:

Electronegativity is the tendency for atoms to keep electrons closer to them. So, if the atoms are smaller there, there is a stronger pull on the electrons to keep them closer. So, the larger the atom get, due to electron shielding, it become less electro negative. I hope this help. You might get a better explanation from Khan Academy's video on Electronegativity

Answer:

A relationship is intuitively expected

Does electronegativity relate to atomic radius? A relationship is intuitively expected between electronegativity and radius: the size of an atom is determined by the distribution of electrons around its nucleus. The closer the electrons are to the nucleus, the more tightly they are bound, thus increasing the electronegativity of the atom.

Blank 1: polar
The difference in electronegativity between N and H causes electrons to preferentially orbit N, making the bond polar.

Blank 2: trigonal pyramidal
There are four “things” attached to N - 3 H’s and 1 lone pair of electrons. The four things together are arranged into a tetrahedral formation. However, the lone pairs don’t actually contribute to the shape of the molecule per se; it’s only the actual atoms that do. The lone pair creates a bit of repulsion that pushes the 3 H’s down, creating a trigonal pyramidal shape (as opposed to a trigonal planar one).

Blank 3: polar
The molecule as a whole is also polar because the “things” around it, though arranged in a tetrahedral pattern, are not all the same. The side of the molecule with the lone pair is slightly negative, while the side with the 3 H’s is slightly positive due to the differences in electronegativity described above.

Read the Safety Data Sheet of hydrogen peroxide to identify the recommended way to store this substance. Choose one:_______.

Lena [83]

Answer:

The correct option is C.

In a tightly closed container in a dry and well-ventilated place

Explanation:

Hydrogen peroxide should be store in a tight closed container and ventilated area because it is an oxidizing agent and it's has oxidizing characteristics. If to is exposed or the bottle lid is broken and exposed it can react and liberate oxygen and heat. It can react with the air and chemical it is exposed with. This will make it to be less effective and there will be a change in it's composition.
