All chemical elements are formed from protons, neutrons (excepting H-1) and electrons.
They are alike because some are made out of the same elements.
All neutrons are alike. As the name suggests , they are neutrally charged particles in the nucleus of an atom. They carry the same mass as a proton. They are found in the nucleus of an atoms together with the protons. However, atoms of a given element are isotopes of one another, if they have a different number of neutrons. e.g. Hydrogen , exhibits three isotopes. #1 protium ; 1 proton, 0 neutrons, 1 electron.( commonest isotope) #2 deuterium ; 1 proton, 1 neutron, 1 electron. ( heavy hydrogen) #3 tritium ; 1 proton, 2 neutrons, 1 electron. ( super heavy hydrogen and radio -active). Note in this table the number of neutrons in each isotope. The next element in the Periodic Table is Helium #1 helium ; 2 proton, 2 neutrons, 2 electron. Note the same number of neutrons as tritium , but now has two protons. A Neutron, in nuclear physics, can disintegrate to form a proton and an electron.
They are all Elements and They are diiferent substances
they both have an particular feel.
the number of protons
An organism that has genes that are alike for a particular trait is called homozygous for that trait. This means that it has two identical alleles for that specific gene.
The chemical elements in a group have similar properties.
Both are composed from chemical elements.
They have the same number of protons and electrons.
its when too atoms are alike
Compound are all alike because they all have two elements combined together like iron+sulfide=ironsulfide
