Answer:
By the result of the formation of positive and negative ions, Ionic compounds are formed.
Explanation:
Electrons are actually transferred from one atom to another to form rare gas electron structures for each ion. The atom which forms a positive ion loses electrons to the atom which gains electrons to form a negative ion. A compound is not stable unless the number of electrons which are lost and gained are equal
Answer:
you didnt put a question lol
Explanation:
Three of the functions of proteins are as antibodies, as enzymes and as messengers. As antibodies, they protect the cells from diseases ie they fight diseases. As enzymes, they regulate the chemical reactions within cells, and thirdly they transmit signals as messengers such as hormones do in co-ordinating biological processes. Proteins are so diverse because of their unique 3-D structures which their polymers form from the 20 amino acids available as their building blocks.
The five main branches of chemistry are organic chemistry, inorganic chemistry, analytical chemistry, physical chemistry and biochemistry. Chemistry can be further divided into many sub-branches that may fall under more than one of the main branches.
Answer:
Alpha, beta, and gamma particles
Explanation:
A shield of aluminium can effectively block off any form of radiation be it alpha, beta or gamma particles.
Radiations are products of nuclear reactions. These radiations produced are quite harmful and injurious to life.
A thick and appropriate material must be used to block off these radiations so as to properly interact with them in an advantageous way.
A shield of aluminium, a block of lead and any material with a high thickness and density is appropriate for neutralizing these forms of radiation.
