What nonmetals are most chemically reactive? - Socratic
May 20, 2015 · The most reactive nonmetal is fluorine, F. The trend in reactivity in the nonmetals is the opposite of the trend in the metals. In the nonmetals, reactivity increases as you move up a group, and to the left. In the metals, reactivity increases down a group and to the right.
Metal Activity Series - Chemistry - Socratic
Jul 7, 2014 · The metal reactivity series lists metals in order of their reactivity, from highest to lowest from top to bottom. A metal listed above another metal will replace that metal in a single replacement (single displacement) reaction.
Why is francium the most reactive metal? - Socratic
Aug 2, 2018 · Francium is hypothesized to be the most reactive metal, but so little of it exists or can be synthesized, and the longest half-life of its most abundant isotope is 22.00 minutes, so that its reactivity cannot be determined experimentally. Francium is an alkali metal in group 1/IA. All alkali metals have one valence electron. As you go down the group, the number of electron …
What is the most reactive metal on the periodic table?
Nov 22, 2015 · There is never enough francium with which to experiment because its isotopes have a very short half-life (the longest is about 22 min), and there is only about 20-30 grams in the earth's crust at any given time.
What is the family of elements that contains the most reactive …
May 11, 2018 · The family that contains the most reactive metals are the alkali metals. Alkali metals are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). As you move down the column, the metals become more reactive because the nucleus gains more electrons and protons (more electron levels), weakening their electrostatic force. Imagine …
Which alkali metal element is the most reactive? - Socratic
Jan 28, 2017 · The same reaction with potassium will ignite the ethanol. Sodium potassium alloy, which is approximately #NaK_(2.8)# in composition, is a liquidus (and even more reactive than potassium), and for this reason is commonly used to dry low boiling point solvents (i.e. diethyl ether, pentane, and hexanes). There are safe means to decompose these ...
What is the most reactive alkali metal? - Socratic
Feb 6, 2015 · Most people will say francium (Fr) because of its position in the alkali metals group, and it is in theory. It is also probably the answer your teacher is looking for. However, experimentally, cesium (Cs) is the most reactive. The reactivity of the alkali metals increases down the group. In theory, francium (Fr) should be the most reactive, but it is radioactive with a …
What family is the most reactive metals in the periodic table?
May 6, 2018 · The most reactive metals in the periodic tables are the alkali metals, followed by the alkaline earth metals. Because of the alkali metals' electron configuration (wants to give its one electron to another substance), they're highly reactive. For example, any of the alkalis and fluorine, which is very electronegative and wants 1 more electron, would be very dangerous …
How does ionization energy relate to reactivity? | Socratic
Apr 10, 2014 · What is reactivity? Reactivity refers to how likely or vigorously an atom is to react with other substances (atoms, molecules, etc). This is usually determined by how easily electrons can be removed (we call it ionization energy!) and how badly they want to take other atom's electrons (we call it electronegativity). Elements with high electronegativity will be very …
How do valence electrons affect reactivity? + Example - Socratic
Jan 10, 2014 · The most reactive kind of metallic element is a metal from Group 1 (e.g., sodium or potassium). An atom in Group 1 has only a single valence electron. This one valence electron is easily lost to form a positive ion with an #s^2p^6# configuration (e.g., #"Na"^+# or #"K"^+#).
