What is the difference between positive ions and negative ions?
By nature, every atom is electrically neutral. Each atom wants to have a full shell of electrons, but some atoms have a very incomplete shell, so they strive to get more electrons. When an atom of this nature bonds with another - among other possibilities - it may gain, or "steal" electrons from another atom to make up the lack of electrons in their own shell. A positive ion is simply an atom that as lost electrons through this process, therefore there is a positive charge because there are more protons. A negative ion has gained electrons, having a negative charge because there are more electrons.
Can electrons move freely in an insulator?
No, electrons cannot move freely in an insulator. Insulators have a full valence band and a large band gap that prevents the movement of electrons through the material. This lack of mobility is what distinguishes insulators from conductors.
Why is quartz an insulator?
Quartz is an insulator because its crystalline structure does not have any free moving electrons that can conduct electricity. This lack of free electrons prevents the flow of electric current through the material, making it an insulator.
What is a material which electrons do not travel through easily called?
A material through which electrons do not easily travel is called an insulator. Insulators have high resistance to the flow of electric current due to the lack of free electrons available to carry the charge. Examples of insulators include rubber, glass, and plastic.
Why can only negative particles be transferred?
Negative particles can be transferred because they have extra electrons that can be gained or lost during a transfer of charge. Positive particles generally do not transfer because they lack extra electrons to give away.
Why are the noble gases unreactive and how does their electron configuration contribute to their lack of chemical reactivity?
Noble gases are unreactive because they have a full outer electron shell, making them stable. This full outer shell makes it difficult for them to gain or lose electrons, which is necessary for chemical reactions to occur. Their electron configuration, with a complete set of valence electrons, contributes to their lack of chemical reactivity.
Why are the nobles gases nonreactive?
Noble gases have a full outer electron shell, making them stable and unreactive. Their electron configuration does not easily allow them to gain, lose, or share electrons with other elements. This lack of reactivity is what gives them their name "noble."
Why argon very stable and not reactive?
Argon is very stable because it has a full outer electron shell, making it chemically inert. This full electron shell means that argon does not easily gain or lose electrons to form chemical bonds with other elements, resulting in its inert properties and lack of reactivity.
How does the lack of electrons affect the Calvin cycle?
It will not work properly, but there are usually electrons from the carbon dioxide and water needed to perform the Calvin Cycle at all.
Is argon the lazy element?
Argon is often referred to as the "lazy element" because it is an inert gas with a full outer shell of electrons, making it unreactive with other elements. Its stability and lack of chemical reactivity contribute to this nickname.
A very stable electron arrangement in the outer energ level is characteristic what?
A filled valence shell is a very stable electron arrangement in the outer energy level. Atoms undergo chemical reactions in order to achieve a filled valence shell, which is usually 8 electrons, but for hydrogen, helium, lithium, and beryllium it is 2 electrons.
Helium is a completely unreactive element because?
Helium is a completely unreactive element because it has a full outer electron shell, making it very stable and unlikely to gain or lose electrons to form compounds with other elements. Additionally, its small atomic size and lack of available orbitals for bonding further contribute to its inert nature.
Why do the atoms of a noble gas not combine to from diatomic or large molecules?
Because the outermost layer of the shells of the noble gases is filled with the maximum number of electrons - 2 electrons into the s block (s orbital) and 6 electrons into the p block (per 2 in py, px, and pz orbitals).
Which best explains why the noble gases are chemically unreactive?
because the most an atom can have in its outer energy level for electrons is 8 and noble gases have 8 the do not want to react because they want to keep the "octet". reacting means gaining or losing electrons
Why does helium atoms do not react with other atoms?
Helium atoms do not readily react with other atoms because they have a stable electron configuration with a full outer shell of electrons. This stability makes them less likely to form chemical bonds with other elements. Additionally, helium is characterized by its low reactivity due to its very low electronegativity and lack of available orbitals for bonding.
When two atoms do not share electrons?
When atoms bond but do not share electrons this is known as an ionic bod. Here electrons are donated from one of the atoms to another in order to ensure that both atoms have a full outer shell. E.g. MgO or NaCl
How are the elements of the halogen family related?
they all lack one electron in their outer shell, so they're each one atomic number from a noble gas
