The highest electronegativity is in the elements in the top left corner of the periodic table, and the lowest in the bottom right corner. Therefore, traveling up or to the left across the periodic table will increase the electronegativity
Answer:
Radioactive isotopes ranging from 11O to 26O have also been characterized, all short-lived. The longest-lived radioisotope is 15O with a half-life of 122.24 seconds, while the shortest-lived isotope is 12O with a half-life of 580(30)×10−24 seconds (the half-life of the unbound 11O is still unknown).
Answer:
Iron is the element that is produced at the limit of the reaction.
Explanation:
In nuclear fusion 2 lighter nuclei are combined together into a single nucleus releasing a tremendous amount of energy in the process.
Up to fusion of iron the reaction of fusion is exothermic but when iron atom pops out the reaction becomes endothermic and it requires very high amount of energy to fuse iron atoms which is not available thus marking an end to the fusion reaction.
Answer:
Formic acid, citric acid, Oxalic acid, washing soda, baking soda, etc. can be some examples of natural acids and natural bases. They both have domestic, industrial, and various other purposes.
Explanation:
<h3><u>
NATURAL ACIDS</u>
:</h3>
There are lots of natural acids present in our nature. Some of them are the following:
> <u>Formic acid</u>
USE: It is used in the stimulation of oil and gas wells as it is less reactive towards the metal.
> <u>Citric acid</u>
USE: It is considered as the best rust remover as it doesn't harm the metal just remove the rust.
> <u>Oxalic acid</u>
USE: It easily remove iron and ink stains and that's why it is used as an acid rinsing material in Laundries.
<h3><u>
NATURAL BASES</u>
:</h3>
There is a variety of natural base found in our nature which founds a lot of uses in day to day life. some of them are the following:
> <u>Washing soda</u>
USE: It is used in commercial detergent mixture to treat hard water.
> <u>Baking soda</u>
USE: It is the best rising agent used mostly in cooking and for domestic purposes like removing stains, etc..
