Epsom salt is a compound.
Answer:Gained, Lost , Shared
Explanation:
The oxidation state tells you how many electrons an atom has GAINED.................. , LOST....................... , or SHARED........................ , in forming a compound.
Oxidation state is defined as the the total number of electrons that an atom gains or loses when forming a chemical bond with another atom.
----To form an ionic bond for example in NaCl, Na, with 11 electrons and one valence electron in its outermost shell donates or lose that valence electron to Chlorine with 17 electron and 7 in its outermost shell. Therefore Sodium, Na acquires the +1 oxidaton state to become stable and Chlorine acquires the -1 oxidation state to become stable forming the NaCl compound.
To form a covalent compound, There must be sharing of electrons between atoms.For example, in PCl3, The phosphorous atom with atomic number 15 shares its three unpaired electrons with the single valence electrons of three chlorine atoms. making the four molecules to attain stability with Phosphorous having +3 and the chlorine atoms having -1 oxidation states
Ionic compounds are molecules that form through the gain and loss of electrons. A metal atom that loses an electron takes on a positive electric charge .
Answer:
The correct option is: Recency effect
Explanation:
Serial position effect is a concept that describes the <u>effect of the position of an item in a sequence on its recall accuracy</u>. According to this theory, in a sufficiently long list of items, an individual is more likely to recall the first and the last items with greater accuracy than the middle items.
There are two types:
<u>1. Recency effect</u>: <u>The items in the end of the list or series are recalled first and more accurately.</u>
<u>2. Primacy effect</u>: The items in the beginning of the list or series are recalled first and more accurately.
In the given example, Jaden can only recall the abbreviation for the <u>last 5 elements in a list of 30 elements</u>. This tendency is known as Recency effect.
