i want to keep it secret :P
i don't want to give the answer haha...
What else can I help you with?
What are the similarities between ionic crystals and solid metals?
Both ionic crystals and solid metals have a closely packed structure with strong bonds between atoms. They also have high melting points due to the strength of these bonds. Additionally, both types of materials are good conductors of electricity, with metals conducting due to the mobility of electrons and ionic crystals conducting when ions are able to move.
What are the similarities of ionic crystals and solid metals?
Both ionic crystals and solid metals have strong bonding forces between their constituent particles. In addition, they both have high melting and boiling points due to these strong bonds. Furthermore, both types of materials are good conductors of electricity, with metals conducting electricity through free-moving electrons and some ionic crystals through the movement of charged ions.
What are the differences between ionic crystals and solid metals?
Ionic crystalsalways contain two or more elements, and have positive and negative ions in a ratio that leads to electrical neutrality.All the electrons involved in bonding are transferred , they are localised on the ions and are not free to move, so ionic solids do not conduct via electron movement.The ions are arranged in regular lattices which are held together by electrostatic forces.Many ionic solids dissolve in water. (there are many exceptions- such as calcium carbonate)Metals on the other handconsist of just one element and the atoms are arranged in regular lattices.In the simple model of a metal as " ions in a sea of electrons" it is obvious why metals conduct electricity through the free movement of electrons.The sea of electrons model does not explain why the lattice of "ions" doesn't simply fly apart. The delocalisation of electrons in the "sea" actually provides the bonding and in the high melting point transition metals this is helped by a degree of covalent bonding involving electrons in d orbitals.Metals do not dissolve in water.
What forms crystals covalent or ionic?
Crystals can form from both covalent and ionic compounds. Covalent crystals are held together by covalent bonds, where atoms share electrons to form a stable structure. Ionic crystals are held together by ionic bonds, where oppositely charged ions attract each other to form a lattice structure.
Why is that metals are malleable and ionic crystals are brittle is best explaind in terms of their what?
This difference is best explained in terms of their atomic structure and bonding. Metals have a more evenly distributed sea of electrons that allows them to be easily reshaped without breaking. In contrast, ionic crystals have a specific arrangement of ions held together by strong electrostatic forces, making them more prone to breaking when subjected to stress.

Are electrons in ionic crystals tightly bound?
Atoms are bonded in ionic crystals.
Why ionic crystals don't conduct electricity in the solid state?
In the solid state ionic crystals are not dissociated in ions.
Is it possible for metals and non metals to form non covalent bonds?
No. The difference in electronegativity is too great.
What forms when nonmetals and metals are combined?
When non metals and metals are combined, the result is an ionic compound. Often, an ionic compound salt.

Why are metals malleable but ionic crystals are not?
Metals are malleable because their atomic structure consists of closely packed positive ions surrounded by a "sea" of delocalized electrons, allowing the atoms to slide past each other without shattering. In contrast, ionic crystals have a rigid lattice structure held together by strong electrostatic forces between positively and negatively charged ions, making them brittle rather than malleable.
What is the difference between ionic crystals and metallic bonding?
Ionic crystals form when positively and negatively charged ions are held together by strong electrostatic forces, leading to a strong and brittle structure. Metallic bonding occurs in metals, where freely moving electrons surround positively charged metal ions, creating a delocalized electron sea that allows for good electrical conductivity and malleability in metals.
Can you compare and contrast the 4 types of crystals?
Covalent, Metallic, and Ionic crystals have high melting points and densities, but molecular crystals tend to be soft and has a lower melting point. Covalent crystal=covalent bond and Ionic crystal=ionic bond.
