What change occurs to an atom when it forms negative ion​

Answers

Answer 1
Ions are formed when atoms gain or lose electrons. Gaining electrons changes an atom into a negative ion. Losing electrons changes an atom into a positive ion. Individual atoms often do not form ions by themselves.
Answer 2

Ions can be made by single element or covalently bonded group of elements. The covalently bonded group of elements is called polyatomic ion. Therefore, when an atom forms a negative ion, atom become cation.

What is Ions?

Any species that contain charge whether it is positive charge or negative charge is called ions. The example of polyatomic ions are sulfate, phosphate, nitrate etc.

Cation is the species that loose electron and attain positive charge while anion is a species which gain electron and attains negative charge so when anion and cation combine in fixed ration the the overall charge of the molecule is zero that is molecule is neutral, the charge over cation and anion is also called oxidation state. When an atom forms a negative ion​, then atom itself gain positive charge over it and become cation by loosing electron.

Therefore, when an atom forms a negative ion, atom become cation.

Answers

Hey There!_____________________________________Answer:

Washing Soda:

Sodium Carbonate commonly known as Sodium Carbonate is a inorganic compound which used in detergents and to soften the water. Its chemical formula is [tex]Na_{2}CO_{3_[/tex]. It is carbonate base

Lemon Juice:

Lemon juice contain citric acid whose chemical formula is [tex]C_{6} H_{8} O_{7}[/tex]. Citric acid is a weak organic acid thus It is used for disinfectants and cleaning as well.

_____________________________________Reaction b/w Washing Soda and Citric Acid

When Lemon Juice and Washing Soda react, the reaction is just an acid-base reaction and forms trisodium citrate and carbonic acid. The latter is then dissociated into Carbon Dioxide and Water. Carbon Dioxide escapes in the form of bubbles and Sodium Citrate(salt) and Water behind.

(citric acid)+ (sodium carbonate)= (trisodium citrate)+(water)+(carbon dioxide)

The chemistry of glass is complex and research is ongoing, but the current consensus is that glass is a phase of matter all its own, known as an "amorphous solid". Scientists refer to any amorphous solid as a "glass". Glass transitions are highly complex and cannot be treated in the same way as traditional phase transitions.

Solution:

In the given problem, we are to find the number of moles of oxygen gas that will use up 13.6mole of hydrogen gas;

 From the reaction equation;

             2 mole of H₂ will completely react with 1 mole of O₂

         13.6 moles of H₂ will completely be used up by [tex]\frac{13.6}{2}[/tex] mole of  O₂
