The incomplete table below shows selected properties of compounds that have ionic, covalent, or metallic bonds. Row Bond Electrical conductivity Likely property 1 Ionic Yes High melting point 2 ? Yes ? 3 ? No ? Which information would best fill the blanks in row 3? metallic bond and low melting point metallic bond and high melting point covalent bond and low melting point covalent bond and high melting point
Answers
Answer : The correct option is "covalent bond and low melting point"
Explanation :
Solids can be divided into 3 types.
1) Ionic solid : This type of solid is formed when a metal atom transfers on or more electrons to a non metal atom. During this process a positive and a negative ion are formed which are joined together by ionic bond.
Ionic compounds have very high melting and boiling points due to the strong electrostatic force that exists among its ions. They have crystalline structure and can carry electricity when dissolved in water.
2) Covalent solid : This type of solid is formed when 2 non metals share their valence electrons forming a covalent bond. Covalent compounds have low melting point and they do not carry electricity as they are not able to form ions in solution.
3) Metallic solid : A metallic solid is formed when 2 metals bond with each other by metallic bond. The valence electrons in metal are loosely held and jump from the valence orbital. These free electrons are able to move throughout the metallic structure carrying electricity. Metallic solid also have high melting points.
Based on above discussion, the correct answer for the blanks in row 3 is "covalent bond and low melting point"
Matter is anything that occupies space .there are different states of matter and the different stated depends on the forces bonding the particles together .the forces include cohesive forces ,weak van nda wall forces and metalic or covalent bonds
Metals have covalent bonds or the metalic monds that holds their particles together .their atoms are compacted together hence conducting electricity and heat
Cohesive forces is the force in action in liquids ,they are not as strong as metalic bonds and lastly the weak van nder wals forces .they are weaker and in most cases involved in gases
