Which phrase best describes a metallic bond?
A metallic bond is one where delocalized valence electrons of the metal are attracted to any of the metal cations. The electrons are delocalized meaning they do not stay with any particular nucleus. The bonds are held together by electrostatic interaction between the delocalized electrons and the positive cations.
How many electrons are in a vanadium atom?
A valence electron is the number of electrons found in the outermost layer of an atom. An atom needs 8 valence electrons in order to be stable and undergo chemical reactions. Since vanadium is in period 4, it goes to the 4th shell, the N shell. When you draw the diagram you put 2 in the K shell, 8 in the L shell, 11 in the M shell, and 2 in the N shell. Most atoms should have 18 atoms in the M shell. Therefore, vanadium has 2 valence electrons.
What term best describes the phrase something that happens?
"Event" is a term that best describes the phrase "something that happens" as it denotes a happening or occurrence at a specific point in time.
What words describe light?
The words that best describe 'light mind' are "frivolous, scatterbrained, harebrained".
Why cu and ag are good conductor?
They have a large number of free electrons. Having lots of free electrons make it easier to move the electrons around this creates a good electric current. They best conductors (silver, copper, gold and aluminum ). Cost, weight and ease of handling also make it a more popular material.
What best describes a valence electrons?
Valence electrons are the outermost electrons in an atom that are involved in forming chemical bonds with other atoms. They determine the atom's reactivity and ability to form compounds. The number of valence electrons can also be used to predict an element's chemical properties.
How many valence shell electrons are there in semiconductor atoms?
Silicon, the most widely used semiconductor, has four valence electrons. This places it in between the conductive metals, which have one to three valence electrons, and the non-conductive non-metals which have five to eight valence electrons.
What is the main reason so many molecules are made from carbon atoms?
Because , Carbon has 4 valence electrons , which is the best number of valence electrons , because it can easily give or take or share that number . . (: ~ Hope this heelps . <3
What phrase describe the basis of income taxes?
Which phrase best describes the basis of seals taxes
What best description of the end result of chemical bonding for most atoms?
getting a ful set of valence electrons
What is the best description of the end result of chemical bonding for most atom?
Getting a full set of valence electrons
What is the best description of the end result of chemical bonding for the most atoms?
Getting a full set of valence electrons
What best describe electrons located in atoms?
This is the atomic orbitals theory.
What best explains how two oxygen atoms each with six valence electrons can bond with each other?
Two oxygen atoms can form a double bond by sharing two pairs of valence electrons between them, resulting in the formation of an oxygen molecule (O2). This double bond allows both atoms to achieve a stable configuration with a full outer electron shell of eight electrons, following the octet rule.
How is valence and reactivity related?
Valence electrons are the electrons on the outer shell of an atom. Valence electrons help to determine the reactivity of a substance because atoms do their best to "fill" their outer shell with 8 electrons, thus achieving a more stable energetic state. Different atoms have different numbers of valence electrons, which affects their reactivity. For instance, noble gases are inert because they possess a full set of valence electrons and don't need to "borrow" or "give away" electrons to have a full outer shell. Halogens, on the other hand, are 1 electron away from filling their outer shell, and are very reactive as a result (they attempt to "borrow" an electron with other atoms by forming a chemical bond).
What makes copper and aluminum conductive?
The outer electron shell of an atom is called the valence shell. The electrons in the valence shell are called valence electrons. The valence electrons of most metals are not very well bound to the atom making them good conductors. The kinetic energy of the valence electrons of an element is determined by the amount of valence electrons (less is better, one is optimal) and the distance of the valence electrons from the nucleus. Example: Silver is the best metallic conductor, it has five shells with one electron in it's outer shell, copper has four shells with one electron in it's outer shell. Silver's fifth shell is further away from the nucleus than copper's fourth shell making silver a better conductor even though they both have one valence electron.
Which phrase best describe realism in modern art?
Painting what the eye is seeing.
