What is the key difference that causes atoms of one element to differ from the other atoms of all other elements?
The key difference that causes atoms of one element to differ from all other elements is the number of protons in their nucleus. This number, known as the atomic number, determines the element's specific properties.
What is a pure substance where atoms of two or more elements are chemically bonded to one another?
A compound is a pure substance where atoms of two or more elements are chemically bonded to one another. This bonding creates a new substance with unique chemical and physical properties different from its constituent elements. Examples include water (H2O) and sodium chloride (NaCl).
What are the main ideas of Dalton theory?
The ancient Greek philosophers had talked about atoms, but Dalton's theory was different in that it had the weight of careful chemical measurements behind it. It wasn't just a philosophical statement that there are atoms because there must be atoms. His atomic theory had these fundamental points :Elements consist of tiny particles called atoms.Elements are pure because all atoms of an element are identical and that in particular they have the same mass.Elements differ from one another because atoms of each element are different from one another; in particular, they have different masses.Compounds consist of atoms of different elements combined together. Compounds are pure substances (remember they cannot be separated into elements by phase changes) because the atoms of the different elements are bonded to one another somehow, perhaps by hooks, and are not easily separated from one another.Compounds have constant composition because they contain a fixed ratio of atoms and each atom has its own characteristic weight, thus fixing the weight ratio of one element to the other.Chemical reactions involved the rearrangement of combinations of the atoms in a substance.Dalton's Atomic Theory had several main points, which are variously grouped into five statements :1) All matter is made of atoms.2) Atoms of a given element are identical in size, mass and chemical properties.3) Atoms of different elements have different masses and properties.4) Compounds are formed by a combination of two or more different kinds of atoms. The elements combine in simple, whole-number ratios.5) Atoms cannot be subdivided, created, or destroyed, but merely rearranged in their compounds with other elements. They can be combined, separated, or changed in the way in which they are arranged.
Atoms of different elements are what?
Atoms of different elements are characterized by the number of protons they contain in their nucleus, which determines the atomic number and identity of the element. The arrangement and number of electrons in the electron cloud surrounding the nucleus also vary among elements. Additionally, different elements have unique chemical properties based on how their atoms interact with one another.
Do atoms include molecules electrons elements and protons?
No. Atoms contain protons, neutrons and electrons. An element is a substance consiting of atoms with the same number of protons. A molecule is a particle consisting of two or more atoms covalently bonded to one another.
How atoms and elements differ from one another?
An element is a composition of many atoms. Thus you can hold NaCl (salt) in your hand. You can't hold the atoms it makes up.
Atoms of one element differ from atoms of another?
By number of protons/electrons.
What is the key difference that causes the atoms of one element to differ from the atoms of the other elements?
number of protons
How may atoms of the same element differ from one another?
Atoms of the same element can differ from one another in their atomic mass, which is determined by the number of neutrons in the nucleus. These variations are called isotopes. Isotopes of the same element have the same number of protons but different numbers of neutrons.
What is it called when atoms of different elements bond to one another?
Fusion
How do monosaccharides differ from one another?
Monosaccharides differ from one another in the following ways: The number of carbon atoms they contain. The orientations of their hydroxyl group. The location of their carbonyl group.
What is the key difference that causes atoms of one element to differ from the other atoms of all other elements?
The key difference that causes atoms of one element to differ from all other elements is the number of protons in their nucleus. This number, known as the atomic number, determines the element's specific properties.
Does the composition of the same compound differ from on location to another?
No, the composition of the same compound does not differ from one location to another. A compound has a fixed chemical formula regardless of where it is found. The arrangement of atoms and elements within the compound remains consistent regardless of its location.
Does balance refers to the way basic elements in the design differ from one another true or false?
false
What is similar for elements located next to one anthor anywhere on the periodic table?
Their atomic number differ by 1. It is applicable for elements located next to one another.
What is the basic building block of all the compounds?
The basic building block of all compounds is atoms. Compounds contain atoms of at least two different elements bonded to one another. Thus, atoms of elements are what form compounds.
Why do elements consist of atoms?
Elements are just one type of atom. An element is a group of atoms of one type.
