What arethree alkaline-earth metals besides calcium?
Beryllium, magnesium and barium are three more alkaline earth metals.
What is the smallest subatomic particles?
Of the three basic particles that atoms are made of, the electron is the smallest.
What element is an example of an alkaline earth metal?
None. The alkaline earth metal isotope with the fewest neutrons would be beryllium-7 with three neutrons and a half-life of 53 days.
What are the three physical forms in which a substance can exist?
They are the three states of matter.SolidLiquidGas
What are three forms of water that can change the surface of the earth?
The three forms on earth are: Solid, Ice, Gas
Electron configuration of beryllium plus?
There are four electrons in a Beryllium atom. Hence the mono positive ion has only three electrons. Therefore the electron configuration is 1s2 2s1.
What are three rules for writing the electron configurations of elements?
Three rules aufbau principle, the pauli exclusion,and the hunds rule
How many elements make up beryllium sulfite?
Beryllium sulfite is composed of three elements: beryllium, sulfur, and oxygen.
What is the ionic charge for beryllium and nitrogen?
Beryllium typically has an ionic charge of +2 because it loses two electrons to achieve a stable electron configuration. Nitrogen, on the other hand, generally has an ionic charge of -3, as it tends to gain three electrons to fill its outer shell. Together, these charges can combine to form compounds, such as beryllium nitride (Be3N2).
Formula for combination of elements Be and N?
There could be three combinations of Beryllium and Nitrogen, depending on the oxidation number of nirogen. The left column is oxygen's oxidation number and the right column is the formula. -1 BeN2 -2 BeN -3 Be3N2
What is the name of this element BeCrO4?
There are three elements that make up the compound beryllium chromate: Be = beryllium Cr = chromium O = oxygen
What is the Lewis structure for beryllium phosphide?
You would need to have to phosphate atoms and three berylium. P P P (with their respective dots- so each with 5) and then B B (with two dots) Then you can make arros pointing from the phosphorus to each Berylium atom.
What atom forms three covalent bonds?
The elements of V- A group of periodic table form three covalent bonds as Nitrogen forms NH3 and phosphorus forms PH3.
How many electron pairs are on the boron atom in BCl3?
There are exactly three electron pairs attached to the Boron atom, each one of them bonded to a chlorine atom as well.
How many different elements make up beryllium sulfite BeSO3?
The elements in beryllium sulfite can be easily determined by looking at the formula. They are beryllium (Be), sulfur (S), and oxygen (O).
What are the three of the many possible shapes of molecules?
Without given a specific molecule there is not any way to determine the shape. Beryllium chloride consists of beryllium in the middle and a chlorine on each side, and is in the shape of a straight line.
Why do halides of Be polymerise?
Beryllium is covalent and polymeric. Each beryllium atom is bonded to four hydrogen atoms and each hydrogen atoms forms two bonds as it is bridiging two Be atoms. Since Be has two valence electrons and H only one, it is apparent that there are not enough electrons to form the usual electron pair bonds in which two electrons are shared between two atoms. Instead of this , three-center bonds are formed in which a 'banana-shaped' molecular orbital covers three atoms BE...H...Be, anc contains two electrons.The monomeric molecule BeH2, if formed with normal bonds, would have only four electrons in the outer shell of the beryllium atom and would be electron deficient. This would make the molecule very unstable; that is why BeH2 exists as polymer.
