Why did John Dalton think that elements are made of single atoms?
The constant proportions - combining different substances into other substances always required the same proportions of each substances; in the case of gases, the numbers come in simple ratios. For example, 2 volume units of hydrogen + 1 volume unit of oxigen combine to form water.
A neutral atom has the same number of protons as it does neutrons?
no. an atom is made up of protons neutrons and electrons. protons have a charge of plus one electrons have a charge of minus one neutrons have no charge. therefore the number of protons and electrons must be equal (balancing the charges) for the atom to be neutral. ;)
How does the idea of atoms explain the priciple of conservation of matter?
The idea of atoms explains the conservation of matter. In chemical reactions, the number of atoms stays the same no matter how they are arranged. So, their total mass stays the same.
Why do all atoms have a different number of protons?
Dear questioner,As an answer to your question I should mention there are atoms which have the same number of protons but are considered different. These atoms are called Isotopes. Isotopes of an element have the same number of protons but the number of Neutrons are not the same. Isotopes have the same chemical virtues but in the physical virtues related to mass they are a bit different.
Isotopes are atoms that have the same number of protons but a different?
Isotopes are atoms of a given element that have the same number of protons but a different mass number and therefore a different number of neutrons.
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.
In a sample of pure copper all atoms have the same what?
In a sample of pure copper, all atoms have the same number of protons, which determines the element's identity.
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.
Is copper an element which is made up of atoms?
Yes, copper is an element that is made up of atoms. Each copper atom contains the same number of protons in its nucleus, giving it unique chemical properties that define it as copper.
Is copper only made up of certain types of atoms?
Yes, copper is composed of only one type of atom, which is the element copper itself. This means that all copper atoms have the same number of protons in their nucleus.
Is substance made of copper atoms and chlorine atoms combined together will have the same chemical properties as copper and chlorine individually true or false?
False. When copper atoms and chlorine atoms combine to form copper chloride, the resulting substance will have different chemical properties compared to copper and chlorine individually. This is due to the new chemical bonds formed between the atoms, leading to a different chemical structure and behavior.
What must atoms of the same element have?
All atoms of the same element have the same number of protons, which is its atomic number. A neutral atom will have the same number of electrons as protons.
How many electrons in 2.9 grams of copper?
To find the number of electrons in 2.9 grams of copper, you first need to determine the number of moles of copper using its atomic mass. Copper has an atomic mass of 63.55 g/mol. Next, you can use Avogadro's number (6.022 x 10^23) to calculate the number of copper atoms, and since each copper atom has 29 electrons, you can multiply the number of atoms by 29 to find the total number of electrons.
Why are compounds of zinc white but compounds of copper have color?
Compounds of zinc are white because zinc atoms do not absorb visible light in the same way that copper atoms do. Copper compounds have color because copper atoms absorb certain wavelengths of visible light, leading to the perception of color in the compound. This difference in electronic structure is responsible for the variation in color between compounds of zinc and copper.
What part of an atom can be used to determine if two atoms are the same element?
Number of protons.
The number of these must be the same for all atoms of an element?
The number of protons is identical in all atoms of an element.
What do you call the particles inside a piece of copper?
Copper is precipitated from geothermal heat vents, And the atoms well colect the same over and over tell the copper material is large enough to see, though with small change`s in mineralization in the insolution the form of the copper well grow in many shapes and size`s.
