the atoms are very tightly packed together as there are strong forces of attraction
What else can I help you with?
Given that a large number of non-metalsare gases what does it tell you about the densities of non-metals in general?
In strict logical inference, nothing, because there could be very dense nonmetals to compensate for the gases. However, in fact the densities of nonmetals on average are less than the densities of metals.
Is hf metal or non metal?
Hydrogen fluoride (HF) is a compound composed of hydrogen and fluorine atoms. Fluorine is a non-metal, while hydrogen is a non-metal as well. Therefore, HF is considered a covalent compound rather than a metal or non-metal.
Which has a greater attraction for electrons Ca or O?
Oxygen (O) has a greater attraction for electrons compared to calcium (Ca) due to its higher electronegativity. Oxygen, being a non-metal, has a higher tendency to attract and share electrons in chemical reactions, while calcium, being a metal, typically loses electrons to form cations.
Typical properties of an ionic compound?
Ionic compounds are typically formed between metals and non-metals through the transfer of electrons. They have high melting and boiling points, are brittle and form crystal structures. They conduct electricity when molten or in solution, but not as solid.
Is oxygen a metal or a non-metal?
Oxygen is a non-metal. It is a reactive gas that is essential for sustaining life and is found in the non-metal group on the periodic table.
Given that a large number of non-metalsare gases what does it tell you about the densities of non-metals in general?
In strict logical inference, nothing, because there could be very dense nonmetals to compensate for the gases. However, in fact the densities of nonmetals on average are less than the densities of metals.
Do nonmetals have lower densities than metals?
Generally, nonmetals have lower densities than metals. This is because nonmetals have fewer electrons in their outer shell, leading to weaker metallic bonds and therefore lower densities. However, there are exceptions, such as nonmetals like iodine and sulfur which have densities comparable to some metals.
In which of the oxides: manganese (IV) oxide or magnesia is a greater percentage by mass of non-metal, and in which there is a greater percentage by mass of metal. Give the formulas of both oxides, write down the calculations and the answer?
ammonium carbonate
Is hf metal or non metal?
Hydrogen fluoride (HF) is a compound composed of hydrogen and fluorine atoms. Fluorine is a non-metal, while hydrogen is a non-metal as well. Therefore, HF is considered a covalent compound rather than a metal or non-metal.
Does iron form more covalent bonding than silicon?
No. Since silicon is a non-metal, it has a greater tendency to engage in covalent bonding as compared to iron
What is pilling bedworth rule?
According to Pilling-Bedworth rule, if the volume of oxide layer formed is greater than the volume of the metal, the oxide layer is protective and non-porous. However if the oxide layer formed has volume lesser than that of the underlying metal then the oxide layer is porous and non-protective.
What are the special characteristic of metal and non metal?
Metals are often hard. They conduct both heat and electricity. They often have high densities, high melting points, and high boiling points. And always loose electrons when bonding. Non-metals are the opposite of all the above characteristics.
What two elemts will form non covalent bounds?
Two elements will form ionic bonds if the electronegativity difference between them is greater than 1.6 -2.0. Opinions vary as to the exact differences. Metals typically have low electronegativities which is where the simple rule metal with non metal comes from.
How do you differentiate a metal from a nonmetal using instrument?
A metal conducts heat better than a nonmetal. If you put a metal and a non-metal in boiling water for the same amount of time, the metal will be hotter than the non-metal. If you put a metal and non-metal in ice water for the same amount of time, the metal will be colder than the non-metal. Also, metal conducts electricity better than non-metal. You can use metal and non-metal wires to conduct a battery, and see which one works better.
How can you tell if an atom has a covalent bold?
If it is a non-metal to non-metal bond than it is covalent. For example, CO2 is a covalent bond.
Arrang the metals and non-metals in table according to their densities What general conclusion can you draw from your list?
The metals and non-metals have been arranged according to their densities in the periodic table.
What do you call any metal other than iron or iron alloys?
a non-ferrous metal
