What are the only elements that exist in nature as in uncombined atoms?
The noble gases, gold and platinum.
What are elements that exist in nature as uncombined atoms called?
Elements that exist in nature as uncombined atoms are called native elements. Some examples include gold, silver, copper, and graphite. These elements are typically found in their pure form due to their stability and inert nature.
Do uncombined atoms have the same number of neutrons as protons?
Uncombined atoms have the same number of neutrons as protons only if they are isotopes of the element, which means the atoms have the same number of protons but different numbers of neutrons. Otherwise, atoms with the same number of protons and neutrons would be considered as different elements.
What are the only elements in that exist you nature as isolated atoms?
Helium, neon, and argon are the only elements that exist in nature as isolated atoms, due to their stable electronic configurations that do not readily form chemical bonds with other elements. These elements are known as noble gases for their inert nature.
Why do you have to mix a 2 elements to make a compound?
Part of the definition of a compound is that it must contain atoms of at least two distinct elements.
What elements do elements and compounds have in common?
Elements and compounds are both composed of atoms. Compounds are composed of two or more atoms of different elements.
Atoms of copper and iron?
Atoms of copper and iron are elements that make up the periodic table. Copper atoms have 29 protons in their nucleus, while iron atoms have 26 protons. Both elements have distinct physical and chemical properties due to their unique atomic structures.
When do atoms combined?
They combine with other atoms when they form a molecule. They do so because the energy state of the molecule produced is less than the energy state that existed in the uncombined atoms.
How many elements are in the compound Fe2 O2?
The compound Fe₂O₂ contains two different elements: iron (Fe) and oxygen (O). Specifically, it has two iron atoms and two oxygen atoms. Therefore, there are a total of 2 distinct elements in the compound.
How many elements are in Sr3(PO4)2?
The chemical formula Sr3(PO4)2 contains three elements: strontium (Sr), phosphorus (P), and oxygen (O). Specifically, it has three strontium atoms, two phosphorus atoms, and eight oxygen atoms, giving a total of 13 atoms. Therefore, while there are three distinct elements, there are a total of 13 atoms in the compound.
Why zero group elements are mono atomic?
Zero group elements are considered monoatomic because they consist of single atoms that do not bond with each other. In a group with zero elements, there are no interactions or combinations possible between atoms, leading to monoatomic nature.
How many elements are al2(SO3)3?
The chemical formula Al2(SO3)3 contains three different elements: aluminum (Al), sulfur (S), and oxygen (O). There are two aluminum atoms, three sulfur atoms, and nine oxygen atoms in total. Therefore, there are three distinct elements in the compound.
