The properties of the atom
electron - electron cloud protons and neutron- nucleus
Nuclei of atoms contain protons (+) and neutrons. The electrons (-) circle the nucleus on orbitals, forming the electron cloud. In a balanced or neutral atom, there will be the same number of protons in the nucleus as there are electrons outside of the nucleus. The number of neutrons can vary within the same element; that's how you get isotopes (e.g. Carbon-13 has 6 protons, 6 electrons, and 7 neutrons...The 13 is the atomic mass representing the sum of the protons and neutrons)
I'm assuming that by "change" you mean alter the quantity thereof. If you want to actually change a proton into a nuetron and eject a positron, that requires a nuclear reaction. The protons and neutrons are in the nucleus and serve to define the atom, while the electrons orbit the nucleus and ultimately determine the atom's charge. Electrons can be removed or added with a certain amount of energy. This energy is relatively small compared to the massive amounts required to alter the subatomic particles within the nucleus.
berylium has 4 protons. It has 4 electrons too.
Bcoz protons r inside nucleus and protons r outside nucleus and properties of element depends upon them.
The number of protons in a nucleus depends on which element it is. ( The number of protons is the decider as to which element it is. ) The number of electrons in an atom is the same as the number of protons in the nucleus, but none of the electrons are in the nucleus. Rather, they orbit around the nucleus like planets round a star.
The number of protons in the atomic nucleus determines the properties of an element. Every element has its own unique number of protons, called its atomic number, which is displayed on the periodic table. The elements are arranged in order of increasing atomic number on the periodic table.
The smallest unit that shows the properties of an element is an atom, and yes, an atom has protons and neutrons in the nucleus.
An atom is the smallest amount of an element that still retains that element's properties. An atom is made up of protons, neutrons, and electrons. Protons have a positive charge, and are part of the nucleus. Neutrons have no charge, and are part of the nucleus as well. Electrons have a negative charge, and orbit the nucleus. Scientists also believe that protons and neutrons are made up of quarks.
neutrons, electrons, and protons
The atomic number of an element is how many protons and electrons (you must have the same amount of protons as electrons) an element has in it's nucleus. The Atomic number= number of protons= number of electrons.
the smallest component of an element having the chemical properties of the element, consisting of a nucleus containing combinations of neutrons and protons and one or more electrons bound to the nucleus by electrical attraction; the number of protons determines the identity of the element.
A molecule is the simplest complete structural unit of an element or compound that can exist in nature. An atom is the smallest component of any element having all the chemical properties of that specific element.
the number of neutrons, protons, and electrons
The number of electrons and neutrons may differ for atoms of the same element. However, what distinguishes atoms of one element from those of a different element is the number of protons in the atom's nucleus. All of the atoms of an element have the same number of protons, which is the single most important determiner of the properties of an element.
It is the number of protons in the nucleus of the atom and it determinnes many properties of the atom. The atomic number is also the number of electrons and is a constant for every element
