What were the first elements that were found in the periodic table?
The first elements in the periodic table are hydrogen, helium, lithium, beryllium, boron.
Which three elements have the fewest protons and neutrons?
hydrogen, helium, and lithium
Is lithium or Neon more reactive?
Lithium is more reactive than Neon.
What elements are more reactive than lead?
In the group 2 elements, the reactivity of the metals increase as you move down the group. The order of reactivity in group 2 is barium, strontium, calcium, and magnesium.
What are the first two elements to form when hydrogen nuclei undergo fusion?
helium & lithium
Is lithium reactive to other elements?
Yes. Lithium is very reactive to other elements.
Least reactive to most reactive elements Lithium potassium Rubidium.?
rubidium
Which is more reactive lithium or carbon?
Reactivity of any metal depends on its capacity to loose electrons as quickly as possible. Among Lithium, Copper and tungsten, lithium is the most reactive since it looses electrons very quickly and forms its cation. In fact, it is among the most reactive metals.
Why is lithium the most reactant element?
I believe that Fluorine is the most reactive of the elements. Lithium may be the most reactive metal, but don't forget potassium.
What elements did mendeleev group with lithium?
hydrogen
What were the first elements that were found in the periodic table?
The first elements in the periodic table are hydrogen, helium, lithium, beryllium, boron.
What are 2 elements most reactive on periodic table?
Lithium and Fluorine.
Name two most reactive elements in the group alkali metals?
These elements are francium and lithium.
Alkali metals are elements don't combine with other elements?
Alkali metal is a term that refers to six elements: lithium, sodium, potassium, rubidium, cesium, and francium. These elements make up group I of the periodic table of elements. They all form singly-charged positive ions, and are extremely reactive. They react violently with water, forming hydroxides and releasing hydrogen gas and heat. Cesium and francium are the most reactive and lithium is the least.
The least reactive metal in group 1 of the periodic table?
Francium is considered the most reactive of the group 1 elements. This is because it is the largest of all elements in group 1, therefore takes the least amount of energy to lose an electron (Group 1 elements react by losing electrons.)
What are three elements from group1?
Hydrogen, Lithium, and Potassium
What elements are used to create lithium hydroxide?
LiOH so lithium oxgen and hydrogen
