Answer:
The answer to your question is: The first option.
Explanation:
Outer electron shell because these electrons can be readily exchanged with adjacent atoms As is mentioned in the statement, these electrons can be exchanged easily with adjacent atoms, so this is the right answer.
Innermost electron shell because the electrons can be transferred to the nucleus. Innermost electrons can not react as easily as the outermost, because they are protected by the outermost shells. This answer in not correct.
Middle electron shell because they are intermediate in distance between the nucleus and the adjacent atom that bonds with the atom. In order that an electron can react, it must be located in the outermost shell, it is not an advantage to be in the middle shells. This option is incorrect.
Any electron can exchange with adjacent atoms to form a bond; there is no preference. Not any electron can react with another element, only the electrons in the outermost shell can react, this option is incorrect.
Answer:
a) KOH
Explanation:
In the given balanced reaction
2K + 2H2O → 2KOH + H2
In the compound KOH,
The elements are K,O, and H and in the compound, there is one mole each of K , O ,and H.
So the element ratio here is 1 : 1 : 1.
I have already answered 'em..
Answer:
group number
the octet rule
total number of bonds
fewest valence electrons
Explanation:
When drawing the Lewis structure of a molecule, start by determining the total number of available valence based on each element's <u>group number </u>Then, use the total number of electrons needed for each element to be stable, generally based on <u>the octet rule</u> to determine the <u>total number of bonds</u> by finding the difference between the number of needed and available electrons divided by two. Next, identify the central atom, which is the element with the <u>fewest valence electrons</u> other than hydrogen. Finally, arrange the number of bonds around the central atom to fulfill the stable number of electrons for each element.
