Answer :
The steps involved in the lewis-dot structure of 
are :
- First we have to determine the total number of valence electron in .
Number of valence electrons in S = 6
Number of valence electrons in two F atom = 2(7) = 14
Total number of valence electrons = 6 + 14 = 20 electrons
- Placing a bonding pair of electrons between the atoms to form the chemical bonds.
Electrons used in bonding = 4
- The remaining electrons are used as a lone pair for central or terminal atoms to achieve an octet to finish the Lewis dot structure.
Electrons used as a lone pair = 20 - 4 = 16
The image is shown below.
D) The same number of each type of atom will always be present before and after a chemical reaction takes place.
Mass is never created or lost in a chemical reaction, so the atoms of each element must stay balanced.
<u>Answer:</u> In the reaction, magnesium atoms lose electrons.
<u>Explanation:</u>
An ionic compound is defined as the compound which is formed when electron gets transferred from one atom to another atom. These are usually formed when a metal reacts with a non-metal or a metal reacts with a polyatomic ion or a reaction between two polyatomic ions takes place.
Magnesium is 12th element of the periodic table having electronic configuration of 
This element will loose 2 electrons to form 
ion
Chlorine is 17th element of the periodic table having electronic configuration of 
This element will gain 1 electron to form 
ion
By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.
The ionic compound formed is 
Hence, in the reaction, magnesium atoms lose electrons.
Answer:
Sleep homeostasis denotes a basic principle of sleep regulation. A sleep deficit elicits a compensatory increase in the intensity and duration of sleep, while excessive sleep reduces sleep propensity
