True. Metalloids look like metals but are brittle and are not good conductors.

Are metals and nonmetals and nonmetals are both good conductors?
Metals are good conductors. Some non-metals are good conductors, but many others are not.
When acids and bases react they form compounds called salt which are made of metals and nonmetals true or false?
Yes, it is correct.
Are nonmetals invisible?
False
Are metals able to form ionic bonds with nonmetal's true or false?
Yes, ionic bonds typically form between metals and nonmetals because the electronegativity difference between these types of elements is usually large.
Does metalloids have properties of both metals and inner transition metals?
Metalloids are unlike the inner transtion metals and all other metals. They are giant molecules whose bonding could be described as covalent. However consider silicon - perhaps the most widey used metalloid- it has a structure like diamond with tetrahedral bonds- but it is a semiconductor- this is because in molecular orbital terms the antibonding orbitals are sufficiently close to the energy of the bonding orbitals (band gap -using the nomenclature of band theory) for thermal excitation into the antibonding orbitals to take place.This is an oversimplification.
Elements that have same properties of both metals and nonmetals are called semimetals?
If that's a true/false question, then the answer is "false." Otherwise I don't know what you mean.
Is three-fourths of the periodic table nonmetals?
False. its metals
Does nonmetals are highly reactive while metals are completely nonreactive?
It is not true; many metals are very reactive and several nonmetals are nonreactive.
Are metals and nonmetals and nonmetals are both good conductors?
Metals are good conductors. Some non-metals are good conductors, but many others are not.
Most of the materials that make up the earth are nonmetals?
false, most of the materials are metals. Non-metals are usually gases like hydrogen, oxygen and nitrogen. There are many more metals.
When acids and bases react they form compounds called salt which are made of metals and nonmetals true or false?
Yes, it is correct.
Are nonmetals invisible?
False
Are metals able to form ionic bonds with nonmetal's true or false?
Yes, ionic bonds typically form between metals and nonmetals because the electronegativity difference between these types of elements is usually large.
Are some nonmetals invisible?
False
