<u>Answer:</u> The element which is most likely to form negative ion is fluorine.

<u>Explanation:</u>

An ion is formed when a neutral atom looses or gains electrons.

  • When an atom looses electrons, it results in the formation of positive ion known as cation.
  • When an atom gains electrons, it results in the formation of negative ion known as anion.

For the given options:

  • <u>Option A:</u> Aluminium

Aluminium is the 13th element of the periodic table having electronic configuration of 1s^22s^22p^63s^23p^1

This element will loose 3 electrons to attain stable electronic configuration and will form Al^{3+} ion

  • <u>Option B:</u> Copper

Copper is the 29th element of the periodic table having electronic configuration of 1s^22s^22p^63s^23p^64s^23d^9

This element will loose 2 electrons to attain stable electronic configuration and will form Cu^{2+} ion

  • <u>Option C:</u> Sodium

Sodium is the 11th element of the periodic table having electronic configuration of 1s^22s^22p^63s^1

This element will loose 1 electron to attain stable electronic configuration and will form Na^{+} ion

  • <u>Option D:</u> Fluorine

Fluorine is the 9th element of the periodic table having electronic configuration of 1s^22s^22p^5

This element will gain 1 electron to attain stable electronic configuration and will form F^{-} ion

Hence, the element which is most likely to form negative ion is fluorine.

A fire is an example of ________________ reaction, because heat is _____________ the system.
Over [174]

d. exothermic; leaving

  • Exothermic reaction is a reaction that produces heat in the reaction whereas the endothermic reaction is a reaction in which heat is required to be given in the reaction to produce product.
  • Fire is an exothermic reaction.
  • A fire is produced due to oxidation of the fuel in the form of liquid or gas.
  • A fire is an example of combustion.
  • In fire both heat and light are left from fire due to the oxidation of fuel.

Hence, option d. exothermic; leaving is the correct option.

answer the following question by entering the numeric value with appropriate units. if the length of one side of a square is 12.
Tasya [4]
Using the length given '12 m', because the shape of the object is a square all sides are congruent. 
Basically 12+12+12+12=48 or 12 x 4= 48
The answer is 48 m
