Electronegativity
What else can I help you with?
What does electro negativity of an element indicate?
How much an element is attracted to receiving valance electrons. The more electronegative, the more it needs electrons.
Why does an isotope of an element not change what the element is?
Basically, the protons are what hold the electrons in orbit, so they are what determine how the element can bond with other elements, how easily the electrons can break off, and how the electrons configure themselves. The neutrons don't really do much (unless there's a lot of them, then the element become radioactive and they start breaking off).
What is the term for how much an atom wants to attract an electron?
The term which means the amount that a given atom (or radical) attracts electrons is electronegativity.
Why is so much emphasis placed on valence electrons?
Valence electrons play a crucial role in determining the chemical properties of an element because they are involved in forming chemical bonds with other atoms. The number of valence electrons dictates how likely an atom is to gain, lose, or share electrons to achieve a full outer electron shell, which is a stable configuration. This determines how an element will interact with other elements in chemical reactions.
Is a numerical value that reflects how much an atom in a molecule attracts electron?
Linus Pauling defined electronegativity as "the ability of an atom in a molecule to attract electrons to itself."
What is unique about nonmetals with 8 electrons in the outermost energy level?
When an element has 8 electrons in its outer shell, then its valence shell is "complete" and because of the octet rule, the element will be pretty much inert. And then Xenon ruins the pattern T_T
How does electrons shielding affect atomic size as you move down the group?
Shielding affect acts as a barrier for proton to attract electrons, therefore the electrostatic force (the which attracts electrons to protons) becomes much less and electrons become further away from the nucleus of the atom. Because of this, the atomic size increases as you move down the group.
What is the smallest particle of an element called?
The smallest basic particle of an element is an atom. Atoms and molecules formed of them are the smallest particles that have the physical and chemical properties of the element. Atoms, however, are made of smaller particles: electrons, protons, and neutrons, of which the electron is the smallest. There are various supplementary particles that connect or interact with them (e.g. mesons). These atomic particles are formed by the combination of constituent particles called quarks, which do not normally exist in uncombined forms (where, oddly, they would have much greater mass than the particles they constitute).
What is the relationship between an element's number of valence electrons and its reactivity?
When we say valence electron we mean the number of electron left it the outermost shell of element, valence electron can be positive of negetive. If an element need much electrons to be octet, that means that the element is not reactive than the one who will give out electrons, the the one who can give electrons much are less reactive than the one who can give a litle and the reaction will be normal as it is soppused to be, Eg lithium and berylium. Lithium is more reactive than berylium because lithuin has 1valence electron while berylium has 2....reactivity goes with the action of valence electron in an element
Mercury's matter in liquid?
Mercury is a liquid at room temperature. It is an element with 60 protons, 60 electrons and about 120 electrons. It can have a different amount of matter depending on how much of it there is. Answer by: Supernerd
What element is most reactive an en element with 7 valence electrons or an element with 8 valence electrons?
the element with seven valence electrons will be more reactive. The reason for this is that elements want to always want to have a full valence shell (they always want 8, like a noble gas). The element with eight valence electron is happy with its full shell and will not want to get rid of any electrons.
Where can carbon stay for millions of years?
carbon is very much stable as element, and its outermost shell contains 4 electrons.
