How will you find the valency of chlorine, sulphur and magnesium

Explanation:

ANSWER

If the number of electrons in the outermost shell of an atom of an element is less than or equal to 4, then the valency of an element is equal to the number of electrons in the outermost shell.  

If it is greater than 4 then, the valance is determined by subtracting the outermost shell of electrons from 8.

The electrons in Cl, S, and Mg are 2,8,7 ; 2,8,6 ; 2,8,2  

Hence the valency of Cl, S, and Mg are 1, 2, 2 respectively.

Chlorine has 7 valence electrons

Magnesium has 2 valence electrons

Sulphur has 6 Valence electrons

Explanation:

We can find how many valence electrons by looking at the periodic table. For instance chlorine is a halogen and therefore has 7 valence electrons as it is in group 17. Magnesium is in group 2 so therefore has 2 valence electrons.

Sulphur is in group 16 and therefore has 6 valence electrons.

If the group has double digits I.e 16 like sulphur we only look at the second digit i.e. 6 as we can't have more than 8 valence electrons.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
