What is the most electropositive element?
Cesium is the most electropositive stable element. Francium is more electropositive (at least in theory) but only about 30 grams exists on the entire planet as it is highly radioactive so no one has been able to check.cesium is most electropositive element in periodic table.Ceasium
Which is most reactive fluorine bromine or chlorine?
Fluorine is most reactive of the three because it has the highest electronegativity (highest tendency to attract an electron towards itself). Fluorine is in fact the most electronegative element in the entire periodic table. The reactivity of the halogens decrease down the group.Fluorine is more reactive.due to its small size and high electronegativity
Which group on the periodic table would not be reactive chemically?
The noble gases, column 18 or VIII of a periodic table, are the least reactive. However, in the last few decades, compounds of at least the heavier members of this group have in fact been made. Therefore, there is no longer any entire group on the periodic table that is totally unreactive chemically.
What does At stand for on the periodic table?
At is the chemical symbol of astatine. At is a radioactive halogen that is itself the byproduct of the decay of more massive radioactive atoms. It has a very short half life, and the "world supply" of astatine (the amount believed to exist at any particular moment anywhere in the entire mass of the planet) is about one ounce (approx. 30 grams).
What elements in the periodic table start with the letter x?
Only one element in the entire periodic table starts with the letter X, and it is Xenon (Atomic Number 54, Atomic Mass of 131.30, and Electronic Configuration of [Kr]5s24d105p6 ).
Why fluorine is reactive?
Fluorine is very reactive because it has the highest electronegativity of all atoms, and therefore can attract valence electrons from an atom of any other element. Whether the attraction will be sufficient to produce actual reaction depends on the entire environment in which the two kinds of atoms interact.
The element with the symbol Mn in out of group 7 why?
Manganese has the symbol Mn and is not in Group 7 of the periodic table because it falls under Group 7 only when considering transition metals. When considering the entire periodic table, manganese is located in Group 7B.
Do you need to memorize the periodic table for chemistry?
No, you do not need to memorize the entire periodic table for chemistry. It is more important to understand the trends and patterns within the table and how elements interact with each other. Familiarity with the table can be helpful, but it is not necessary to memorize every element.
Which group in periodic table contain elements that are liquids solids and gases at room temp?
The entire periodic table contains elements that are liquids, solids, and gases at room temperature. The state of an element at room temperature depends on its position in the periodic table and its atomic properties, such as melting and boiling points.
Is Fluorine atomic number 9 stable?
No, fluorine gas (F2) is highly reactive and dangerous. Fluorine as an atom is worse, as it is the most electronegative atom in the entire periodic table of elements and thus has a very large tendency to gain one electron to attain stability.
What is an entire chart and all of its elements called?
the periodic table
What is the violin music playing in the Dow Human Element commercial?
The violin music in "The Human Element" commercial containing the periodic table is William Walton's "Touch Her Sweet Lips and Part". It is from the film score for the 1940's film of Shakespeare's Henry V. You can hear the entire piece on YouTube.
