When struck with a sharp blow ionic compounds tend to what while metallic substances which are what change shape?
"When struck with a sharp blow, ionic compounds tend to (crack) while metallic substances, which are (covalently bonded), change shape."This makes the most sense. A lot of ionic compounds form salts which are crystalline and brittle in solid form. This is obviously homework but what a terrible question, right down to the punctuation.
Are metallic compounds brittle?
depends on if they are a solid or gas or liquid. If solid then yes, usually the non metal solids are brittle.
Why some materials are ductile and some brittle?
Materials that contain metallic bonding tend to be ductile because after a small distortion each metal ion is still in exactly the same environment, so the shape is retained. Materials that are brittle tend to be bonded ionically; the structure is held together by the alternating positive-negative charges, if a distortion brings two like-charges together then they repel and the structure comes apart. I'm assuming you have the basic knowledge of metallic and ionic bonding that will allow you to understand my answer, if not, and this doesn't make sense, feel free to message me and I'll try and help you further :)
Does the substance being hit in the photo below contain ionic or metallic bonds.Explain your answer?
Ionic because ionic compounds tend to be brittle solids at room temperature and usually break apart when hit with a hammer.
Elements on opposite sides of the periodic table?
Elements on opposite sides of the periodic table, for example Groups 1 and 17, form ionic compounds. Examples include LiCl, NaCl, KI, and RbBr. The elements in Group 1 are the alkali metals, and the elements in Group 17 are the halogens, which are nonmetals.
Which of these is an example of a compound iron or carbon dioxide or oxygen or calcium?
Carbon Dioxide (CO2). Compounds tend to be made from 2 or more different elements bonded together either covalently or ionically. They are all made of 2 or more elements bonded together whether those elements are the same or not. The other options are elements (Fe, O, and Ca respectively). They are not bonded to anything and therefore do not make a compound.

Is non metallic solids brittle?
They tend to be, yes

Why do atoms tend to be bonded to other atoms'?
The correct answer is: Atoms are often more stable when bonded to other atoms
How do the properties of metals differ from those of both ionic and molecular compounds?
Metals share properties such as: malleability, conductivity, strength and hardness. The reason properties of metals are different is because of metallic bonding. metals are made up of positively charged metal ions in a sea of delocalised electrons. This gives them the properties listed above. Ionic and molecular compounds are bonded in different ways. e.d ionic compounds are bonded in a rigid structure so it is brittle and non conductive
What is three ionic compound?
four properties of ionic compound are: 1-All ionic compounds form crystals 2-Ionic compounds are very hard and very brittle 3-Ionic compounds conduct electricity when they dissolve in water 4-Ionic compounds tend to have high melting and boiling points and 3 ionic compounds are: Sodium Chloride - Na Cl Potassium Fluoride - KF Magnesium Chloride - MgCl2
How does melting point compare among molecular compounds and ionic compounds?
Molecular compounds tend to have lower melting points.
Why are the noble gases are not found as a compounds?
They have very stable electron configuration. They does not tend to make compounds.
