What is an element with 3 atoms?
Anne Marie Helmenstine, Ph. D. Lithium is the element that is atomic number 3 on the periodic table. These means each atom contains 3 protons.
Can an element have 3 atoms?
Other elements contain two or more atoms in their molecular form (Fig. Hydrogen (H2), oxygen (O2), and chlorine (Cl2) molecules, for example, each contains two atoms. Another form of oxygen, ozone (O3), has three atoms, and sulfur (S8) has eight atoms. All elemental molecules are made of atoms of a single element.
What are the 3 atoms called?
Homonuclear triatomic molecules contain three of the same kind of atom. That molecule will be an allotrope of that element. Ozone, O3 is an example of a triatomic molecule with all atoms the same. Triatomic hydrogen, H3, is unstable and breaks up spontaneously.
Can an atom change elements?
Nuclear transmutation is the conversion of one chemical element or isotope into another. In other words, atoms of one element can be changed into atoms of another element by transmutation.
Can a molecule have one atom?
A molecule may be homonuclear, that is, it consists of atoms of one chemical element, as with two atoms in the oxygen molecule (O2); or it may be heteronuclear, a chemical compound composed of more than one element, as with water (two hydrogen atoms and one oxygen atom; H2O).
What are 4 types of atoms?
Different Kinds of Atoms
- Description. Atoms are made of tiny particles called protons, neutrons and electrons.
- Stable. Most atoms are stable.
- Isotopes. Every atom is a chemical element, like hydrogen, iron or chlorine.
- Radioactive. Some atoms have too many neutrons in the nucleus, which makes them unstable.
- Ions.
- Antimatter.
What are the 3 sub particles of an atom?
Given that these particles make up atoms, they are often referred to as subatomic particles. There are three subatomic particles: protons, neutrons and electrons. Two of the subatomic particles have electrical charges: protons have a positive charge while electrons have a negative charge.
Can elements be changed?
Nuclear transmutation is the conversion of one chemical element or an isotope into another chemical element. A transmutation can be achieved either by nuclear reactions (in which an outside particle reacts with a nucleus) or by radioactive decay, where no outside cause is needed.
Can we create new atoms?
Atoms form elements and thus are all around us. We can also make new atoms, by one of the two processes: nuclear fusion and nuclear fission. Fusion is the reaction in which smaller nuclei come together to form larger nuclei. The process of creating atoms is very difficult; in general scientists don’t do this.
Do elements only have one atom?
An element is a pure substance and is made of only one type of atom; it cannot be broken down into a simpler substance.
Is it possible to change one element into another?
Temperatures of thousands of degrees and pressures of hundreds of thousands of atmospheres fail to rearrange the atomic nucleus. One element cannot be changed into another in this way. But it can be done by the methods of a new science called nuclear chemistry.
Can you count the number of atoms in a chemical change?
You can count the number of atoms. You can see how the products combine to form reactants. You can count the number of molecules. You can count the number of atoms. A chemical change resulting from a reaction with oxygen is called _____________. Spontaneous combustion means _____.
How are molecules different from their component atoms?
When atoms interact with one another to form molecules or larger structures, the molecules have different properties than their component atoms; they display what are often referred to as emergent properties, where the whole is more than, or different from the sum of its parts.
Where do the atoms in our bodies come from?
Common answers might be that the atoms in our bodies come from food, water, or air. But these are not the ultimate answers, because we then need to ask, where did the atoms in food, water, and air come from?
