properties of metals

Question 1

magnetism

Answer 1

is a force that can attract or repel objects that have a magnetic material like iron inside them. in simpler words, it is a property of certain substances which pull closer or repel other objects. magnetic objects are always made out of metal but not all metals are magnetic

Question 2

oxidation state

Answer 2

ability to oxidize what takes place by gaining oxygen, losing hydrogen, or losing electrons, and is a chemical property that results in the oxidation number of a substance being changed

Question 3

conductivity

Answer 3

electrical conductivity is when a material allows current to flow through them easily. in contrast electrical insulators resist current passing through the material

Question 4

toxicity

Answer 4

The condition of producing adverse bodily effects due to poisonous qualities. is also how much a substance can damage an animal, plant, cell, organ or other organisms is its toxicity

Question 5

shear strength

Answer 5

measures the largest shear force a material can stand before ripping apart

Question 6

Ductility

Answer 6

the ability of a substance to be drawn, pulled, or extruded through a small opening to produce a wire

Question 7

Malleability

Answer 7

the ability of a substance to be hammered or beaten into thin sheets

Question 8

tensile strength

Answer 8

A measure of how much stress from pulling, or tension, material can withstand before breaking.

Question 9

Elasticity

Answer 9

to be able to flex and bend

Question 10

Plasticity

Answer 10

to be able to be permanently changed by external forces

Question 11

Reflectivity

Answer 11

when the light from an object is reflected by a surface, it changes direction. it bounces off the surface at the same angle it hits it. smooth shiny such as mirrors and polished metals reflect light well

Question 12

toughness

Answer 12

Mechanical Property of a material that indicates the ability of the material to handle overloading before it fractures.

Question 13

resistance

Answer 13

electrical resistivity is a funder mental property that quantifies how strongly a given material opposes the flow of electric current

Question 14

durability

Answer 14

the ability to withstand wear, pressure, or damage.

Question 15

hardness

Answer 15

to be able to resist abrasive wear

Question 16

heat of combustion

Answer 16

another name for burning. it is an example of an exothermic reaction, a reaction that releases energy to the surroundings. this is mostly thermal energy but light energy and sound energy is also released.

Question 17

Compression Strength

Answer 17

to resist pushing or crushing forces
