Because the sun and stars get their energy from thermonuclear fusion: a process in which lighter elements are converted into heavier elements. As a result atoms of these elements have different numbers of positively charged protons and negative charged electrons. This gives the elements different properties. Furthermore, atoms of different elements will combine in different ways to make compounds and, in very many cases, the properties of a compound will be different from those of the constituent elements. For example, water which is a liquid at normal temperature and pressure (NTP) is made up of the elements hydrogen and oxygen which are gases at NTP.
What else can I help you with?
Do all substances have the same force holding them together?
All substances are made up of atoms which have nucleus inside it,since nucleus is same for all whether it be anything,hence all the substances have same force i.e nuclear force.
Are all planets made of the same substances?
NO
Do all substances melt at the same temperature as water?
no
Does all substances have the same flamability limit and same probability to cause a fire?
No.
What do all metals have in common when they react?
they have the elements and they are in the same substances
Are all substances that look the same the same?
No, they are not.For example: table salt and table sugar.(household sugar and salt); salt is sodium chloride(NaCl), and sugar is sucrose(C12H22O2). Therefore no not all substances that look the same are the same.
What do not all substances contract the same in?
Not all substances contract the same when subjected to cooling because each substance has its own unique molecular structure and properties. Factors such as intermolecular forces, atomic arrangements, and bond strengths all play a role in determining how much a substance will contract when its temperature decreases.
Is a substance the same as an ingredient?
A substance can be an ingredient, but not all substances are ingredients.
What are chemical substances called in which all of the atoms have the same number of protons?
Chemical substances in which all of the atoms have the same number of protons are called elements. Elements are the purest form of substances and are organized on the periodic table based on their number of protons.
Are all substances the same before and after burning?
No, some substances change their whole form and others just change their color and shape.
What is the same between a element compound and a mixture?
they all contain 2 substances or more
Describe what is meant by an element?
Elements are pure substances inwhich all the atoms have the same number of protons (same atomic number) and thus have the same chemical properties. They cannot be separated by normal chemical means into any simpler substances.
