What else can I help you with?
Many of the first discovered elements were named by?
Many of the first discovered elements were named by their discoverer or the location where they were discovered, such as hydrogen, named by Antoine Lavoisier, and uranium, named after the planet Uranus.
How many chlor-alkali plants are there in the US?
There are approximately 52 chlor-alkali plants in the United States. These plants produce chlorine and caustic soda through the electrolysis of salt brine.
How do you determine the number of elements using the formula of a compound?
To determine the number of elements in a compound using its formula, you can count the different chemical symbols present in the formula. Each unique chemical symbol represents a different element in the compound. For example, in the compound H2SO4, there are three elements: hydrogen (H), sulfur (S), and oxygen (O).
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.
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
All elements in the ALKALI-METAL family have how many valence electrons?
One
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 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.
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 in the set a b c?
I believe you should be able to count those on your own.
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 are all the elements in the groups often called?
in periodic table،there are many groups of elements. group 1 is called alkaly metals . Group 2 is called alkaline earth metal.
How many valence electrons do alkaline earth metals have?
The alkali earth elements have TWO valence electrons.
How many valence electrons does an alkali metal have?
An alkali metal has 1 valence electron. Group 1 elements, such as lithium, sodium, and potassium, all have 1 valence electron in their outermost energy level.
How many inversions are there in the given sequence of numbers?
The number of inversions in a sequence of numbers is the count of pairs of elements that are out of order.
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
