explain why the number of electrons in the nucleus determines the physical and chemical properties of the atom

Answer 1

First off, the electrons aren't located in the nucleus, only protons and neutrons. The electrons orbit the nucleus.

The electrons in the outer shell of an atom determine it's chemical and physical properties because they determine what other elements or ions they can react with. The relative availability of electrons in one element enables it to donate some to another element that requires them to have a full outer shell (sometimes known as the octet rule, since the first few rows on the periodic table all require eight electrons in the outer shell to be stable) The larger the element, the more electrons (and protons and neutrons), and this gets into electrostatic attraction and repulsion in addition to electron affinity. Electrons are also involved in crystal structure of metals and alloys, and again, how they allow crystal cells to form determines how hard or ductile a crystalline structure can be, how conductive it is to heat or electrical current, etc.

Of course, the number of electrons orbiting the nucleus of an atom is only one factor affecting the physical and chemical properties. The stability of the nucleus is another factor, which has to do with the number of protons and neutrons present as well.

Answer 2

First, the electrons are not in the nucleus. The electrons are in the energy levels surrounding the nucleus. Elements in column 1 have 1 electron in their outer ring and want to give that 1 electron away and become a +1 ion. Column 2 elements have 2 electrons in their outer ring and want to give them away and become a +2 ion. Jumping to the other side of the periodic table, column 18 (formerly called 8) has 8 electrons in the outer ring and is full. These are the inert gases and do not react. Column 17 (or 7) have 7 electrons in the outer ring and would like 8 to be full so they take one(such as from an element in column 1)and become a -1 ion. Elements in column16 (or 6) have 6 electrons in the outer ring and want 8 so they take 2(such as from an element in column 2) and become a-2 ion.It is the electrons that determine the physical and chemical properties.

Answer 3

The sort of protons ought to equivalent the kind of electrons exterior of the nucleus so as that the atom has a independent fee. The atomic selection is used to perceive the element and equals the kind of protons interior the nucleus. The sort of neutrons interior the nucleus might selection for an exact element. This finally ends up in there being isotopes for a given element.

Answer 4

becuz . the number of electrons affects the melting point and boiling point of the atom. the elcetrons sheild one another depending on how many shells there are and also its type of bonding is a big factor in its physical state.

and there are no electrons in the nuclues jimmy boy.
