Many of the first discovered elements were named by?
many of the first discovered elements were named by greek and roman philosophers
How many clams are there in the world?
As many as you can count
How many electron shells in bromine?
Bromine is a member of the halogen family of elements. Its companions include fluorine, chlorine, and iodine. Like the other halogens, bromine has seven electrons in its outer shell and is very reactive. You will find bromine in many salt compounds with alkali metals. Sodium bromide is a compound found in seawater. As with all reactive elements, bromine is never found alone in nature. It is always a part of a compound with other elements. Source: Chem4kids
How many shells does hydrogen have?
All elements in the first period have 1 shell. That's hydrogen and helium.
What was the element americium named after?
America, the country it was discovered in. Many elements are named after the country where they were first found.
All elements in the ALKALI-METAL family have how many valence electrons?
One
How many valence electrons do alkaline earth metals have?
The alkali earth elements have TWO valence electrons.
How many valence electrons do alkali metal family members have?
The key to this answer is the phrase "valence electrons". Alkali metals are in the first column of the periodic table and include elements such as Lithium, Sodium and Potassium. These elements typically lose ONE electron when they participate in a chemical reaction, therefore they have ONE valence electron.
How many Elements does the perodic table have?
At last count we were up to 114.
Alkali metal and alkaline earth metal have how many ionization energies?
Alkali metals (group 1 elements) have one valence electron. Hence have one ionization energy Alkaline earth metals (group 2 elements) have two valence electron. Hence have two ionization energy
How many electrons do group 1 elements lose to become ions?
Group 1 elements a.k.a. Alkali metals lose 1 electron to form 1+ ions
How many alkali metals are on the periodic table?
6: lithium(Li) ,sodium(Na) , potassium(K) , rubidium (Rb) , cesium (Cs) and Francium(Fr). Practically,only the first five can be termed alkali metals,because there is not enough Francium in the planet to examine its characteristics. Of course, the electron structure of the atom of Francium "proposes" an alkali metal.
Many of the first discovered elements were named by?
many of the first discovered elements were named by greek and roman philosophers
How many elements in the set a b c?
I believe you should be able to count those on your own.
Is potash metallic?
Yes, It is. The name "potassium" comes from the word "potash", as potassium was first isolated from potash. Potassium is a soft silvery-white metallic alkali metal that occurs naturally bound to other elements in seawater and many minerals.
Why are the alkali metals so named?
When alkali metals react with water they produce an alkali (basic) solution. No because they form basic oxides and they neutralise acids
What is the formula for an alkali?
An alkali is basically a combination of an alkali metalor an alkaline earth metal and a halogen to form a salt. Let's look at the alkali and alkaline earth metals and see what's up. If you're not familiar with the periodic table, you should make friends with it. It represents a lot of very serious thought power on the part of a bunch of very smart, very clever people. Some spent their entire lives working to expand our knowledge of the ideas represented by this construct. The table is set up in vertical columns and horizontal rows. The first two columns are the Group 1 and Group 2 elements, and they are (respectively) the alkali metals and alkaline earth metals that we mentioned. The halogens are in Group 17 of the table. Fluorine, chlorine and some other elements are in that group. These elements combine in a one-to-one ratio with the alkali elements (Group 1) and in a two-to-one ratio with the alkaline earth metals (Group 2). The combinations make up salts, and they are alkaline compounds. Let's look at an example you're familiar with - table salt. Table salt, NaCl, is a alkali. It's an alkaline compound of an alkali metal and a halogen, sodium and chlorine. Simpe and easy. You need links, and you got 'em. Our friends at Wikipedia post knowledge for free.
