Is copper made up of more than one element?

Yes, the metallic copper is an element, this means 'of one kind of atoms', it is Cu with atom number 29 in the periodic table. A 'copper' (money piece) is not made of pure copper, it is an alloy, the same like a 'nickel'.


Which pair of atoms form a pure covalent bond?

Two atoms of the same element and mass number.


Which sample contains the greatest number of atoms a sample of Al that contains 8.18E plus 23 atoms or a 5.16 mole sample of S?

Which sample contains the greatest number of atoms. A sample of Al that contains 8.18E+23 atoms or a 5.16 mole sample of S?The sample of______ contains the greatest number of atoms.Answer:In order to compare the two samples, it is necessary to express both quantities in the same units. Since the question was phrased in terms of atoms, it is convenient to convert moles of S to atoms of S.The conversion factor between atoms and moles is Avogadro's number: 6.02 x 1023 "things" / molTo convert 5.16 moles of S to atoms of S:atoms S=5.16 mol S6.02 x 1023 atoms S= 3.11E+24 atoms S1 mol SMultiply by atoms per mole. Moles cancel out.The sample of Al contains 8.18E+23 atoms.Since 3.11E+24 is larger than 8.18E+23, the sample of S contains the greatest number of atoms.


What is a pure substance made up of the same kind of atoms called?

This describes an element. There are over a hundred elements in the physical world, and they are all categorized in the periodic table.


What is the formula for copper nitride?

Depends on the oxidation state of the copper ions. If it is copper (I), which is the same as Cu+, then the formula would be Cu3N.On the other hand, if it is copper (II), which is the same as Cu2+, then the formula would be Cu3N2

Is a sample of pure copper all atoms have?

In a sample of pure copper, all atoms have the same number of protons in their nucleus, which defines the element as copper. However, individual copper atoms may have varying numbers of neutrons, resulting in different isotopes of copper.


What is a pure sample of atoms that are all the same known as?

a element is a pure substance


How can you use Dalton's atomic theory to explain why every sample of pure substance has the same properties?

Dalton's atomic theory states that elements consist of indivisible particles called atoms and that atoms of the same element are identical in size, mass, and properties. Therefore, every sample of a pure substance will have the same properties because each sample is made up of the same type of atoms arranged in the same way.

Are all sample of elements are composed of atoms with same atomic mass?

No, different samples of an element can have varying atomic masses due to the presence of isotopes. Isotopes are atoms of the same element with different numbers of neutrons, leading to different atomic masses.


What is a pure substance - all the atoms have the same atomic number or number of protons?

A pure substance in which all the atoms have the same atomic number or number of protons is an element.


How can you use Dalton's atomtic theory to explain why every sample of a pure substance has the same properties?

Dalton's atomic theory states that elements are made up of tiny particles called atoms, which are identical for each element. Therefore, every sample of a pure substance has the same properties because it is composed of the same type of atoms arranged in a specific way, leading to consistent physical and chemical characteristics.


Why is a sample of matter considered a pure substance?

A pure substance is either an element or compound. Elements are composed of only one kind of atom, and compounds are composed of a definite proportion of atoms of different elements that is always the same.


Is a compound same through out?

A sample of a pure compound consists of the same molecules throughout its mass.


What mass of copper contains the same number of atoms as 68.7 g of iron?

To find the mass of copper containing the same number of atoms as 68.7 g of iron, we need to first calculate the number of atoms in 68.7 g of iron using its molar mass. Then, we convert this number of atoms to copper atoms using the ratio of their molar masses. Finally, we determine the mass of copper corresponding to this number of atoms.


Is copper an element which is made up of atoms?

Yes, everything is made up of atoms, but the atoms in copper are all the same kind, just copper atoms, so it is an element.


What is a pure substance all the atoms have the same atomic number or number of protons?

A pure substance is a material made of only one type of particle, such as atoms or molecules, and all the atoms in a pure substance have the same atomic number or number of protons. This means that all the atoms in a pure substance are of the same element.
