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.
Are alkali metals softer or harder than other metals?
The softness of alkali metals has to do with metallic bonding in terms of bonding and anti bonding orbitals. In molecular orbitals, there are the s, p, d orbitals with corresponding anti-bonding orbitals. For alkali metals, the s orbital is only partially filled. This means that the bonds between each atom are weak because only a cloud of s-orbital electrons are holding them together. As we move right across the periodic table the strength of metals reach a maximum at about group 7-8. This is because at this point anti-bonding and bonding orbitals are both partially filled and this maximizes the amount of unpaired electrons that participate in the electron cloud that holds metallic bonds together. As we proceed further right (toward Au) the bonds become weaker because the bonding and anti-bonding orbitals begin to fill and pair up. This means these electrons do not participate in the electron cloud of metallic bonding. Thus a weaker bond (softer metal) is formed.
What kind of bonding is noble gases and metals?
noble gases do not bond with metals.
What metals bond with other elements using metallic bonding?
Predominantly transition metals.
What kind of elements forms after cation bonding?
metals
In a pure sodium are there molecular bonding?
in pure metals, there is molecular bonding. These bondings are known as metallic bonds.
Is N2O3 ionic or molecular?
molecular
Is CCl4 a ionic or molecular compound?
Based off my chemistry class, for bonds to be ionic it must be a bonding of a metal and a non-metal. Since chlorine and carbon are both non metals they can't be ionic, we would call it covalent bond but molecular compound works as well.
Does hydrogen gas have a ionic or molecular?
Hydrogen gas is a molecular compound because it is two non-metals bonding. Non-metal + Non-metal = Molecular compound Metal + Non metal = Ionic compound

What is the bonding process for nonmetals bonding with metals?
the bonding process for nonmetals bonding with metals is that they can take electrons and give them to each other.
Is metallic bonding between metals or non metals?
between metals
How do you know if a bond is ionic or convalent?
An Ionic bond is metals bonding to non-metals. A Covalent bond is non-metals bonding to non-metals.

What atoms share electrons in their outer cell?
Any non-metallic atom can share electrons with another non-metallic atom, through covalent bonding. Metallic bonding is between metals. Covalent bonding is between non-metals. Ionic bonding is typically between a metal and a non-metal.
What accounts for the observed differences in the properties of ionic and molecular compounds?
t Answer Well firstly, ionic compounds form from metals bonding with non metals. Molecular/covalent form from non metals bonding with non metals. A strong electrostatic force between ionic compounds results in them having high melting points. A weaker electrostatic force between molecular compounds results in them having lower melting points and thus weaker bonds. Ionic compounds are made up of ions, so will conduct electricity. Covalent compounds only share electrons and so are not ions, and will not conduct electricity.
