1) Hydrogen and some helium and a fairly small amount of lithium were formed very shortly after the start of the Universe, when matter cooled down enough for quarks to join into nucleons, and for some nucleons to join into heavier elements. There wasn't enough time to form any of the heavier elements.
2) The heavier elements - the so-called metals - were formed inside of stars, by nuclear fusion. In some cases, significant amounts of this matter went back into space, in supernova explosions.
For additional information, I suggest searching Wikipedia orfor the following topics:
These elements have similar chemical and physical properties.
It is chemical. It is chemical because when salt is formed from elements it becomes a chemical and not a physical.
Elements are grouped by their chemical properties. But, in arranging the chemical properties, physical properties are distinguished.
Physical properties are not related to the chemical reactions or chemical behaviours of the elements.
There are three different chemical and physical elements that make up phosphate. These elements are oxygen, potassium and sodium.
Except noble gases the groups of elements in periodic table have the similar chemical properties but not the physical.
elements in the same group
The elements of a chemical compound can be separated only by chemical means, but not by physical means.
This is rightThe outermost electrons account for many of the physical and chemical properties of elements.
The answer to, ' when repeating chemical and physical properties of elements change periodically with the elements' atomic numbers it is called the?'Periodic law, is the answer. PERIODIC LAW !orPeriodicity of the chemical elements properties.
All elements have physical and chemical properties, some are synthetic and not found in nature but none the less are real and so do have properties.
it is the ~group~ of the periodic table of elements
Cadmium is an element. Like all elements it has both physical and chemical properties.
On chemical and physical properties
This is a chemical change.
- the rational arrangement of chemical elements - elements in groups - elements in periods - atomic number - prediction of chemical and physical properties of elements
it is to hard to answer,
physical and chemical properties
The chemical and physical properties of a compound are different than those of the elements from which it is formed.
My head is a physical mechanism
Lead is an element, not a property. All the elements have physical and chemical properties.
All elements have both chemical and physical properties. The question as asked has no meaning.
compounds and elements because only compounds and elements have a specific set of physical and chemical properties.
the chemical and physical behavior of metallic elements
