bonding,structure,properties of matter

Question 1

what are the three states of matter

Answer 1

solid liquid and gas

Question 2

formation of ions

Answer 2

ions are charged particle either posotive or negative charged looses electrons becomes posotivly charged gains electron negative charge

Question 3

metalic bonding

Answer 3

occures between metal only

Question 4

ionic bonding

Answer 4

occurs between a metal aand non metal metal looses electrons to become positivly charged

Question 5

ionic compounds

Answer 5

form structures called giant latties strong electrostatic forces of attraction

Question 6

properties of ionic compounds

Answer 6

high melting point lots of energy needed to over come electrostatic forces of attraction

Question 7

ionic compounds can or cant conduct electricity

Answer 7

cant

Question 8

covalent bonding

Answer 8

sharing of pair electrons between atoms to gainfull outershell occurs during non metal only

Question 9

nanoscience

Answer 9

refers to structure that are 1-100m in size order of few hundred atomshigh surface to area to volume ratio

Question 10

polymers

Answer 10

long chain molecules that are made up of many smaller units cvalled monomers held together by covalent bonds
