What else can I help you with?
If E is the symbol for an element which two what symbols represent isotopes of the same element?
If E is the symbol for an element, isotopes of the same element would have the same symbol "E" but different mass numbers, indicated in the symbol as E-1 and E-2, for example. Isotopes have the same number of protons but different numbers of neutrons.
What is the dot diagram for boron?
The electron dot diagram for boron shows three dots, representing the three valence electrons in the outer shell of a boron atom. These dots are positioned singularly on each side of the boron symbol.
How does the discovery of isotopes contradict Dalton's theory?
It was then changed to "All atoms of the same element contain the same number of protons and electrons, but atoms of a given element may have different numbers of neutrons." after James Chadwick discovered that the nuclei of most atoms contain neutrons as well as protons.
The substance whose Lewis structure shows three covalent bonds is?
Boron is an example of a substance whose Lewis structure shows three covalent bonds. In its Lewis structure, boron typically forms three single bonds with other atoms.
What shows how many atoms of each element are in a unit of substance?
The chemical formula shows you this. The subscripted number next to each element shows how many atoms are present in a molecule or formula unit. If no number is shown, then only one atom of that element is present.
What is the abundance of boron in the earth's crust?
Most naturally ocurring elements are a mixture of different isotopes. Look up boron for more details; I didn't look it up, but I can imagine that it consists of a mixture of isotopes that have an atomic mass of 10 and 11; or perhaps some other isotopes too. Different isotopes of an element have the same number of protons, but a different number of neutrons.
If E is the symbol for an element which two what symbols represent isotopes of the same element?
If E is the symbol for an element, isotopes of the same element would have the same symbol "E" but different mass numbers, indicated in the symbol as E-1 and E-2, for example. Isotopes have the same number of protons but different numbers of neutrons.
Why do isotopes of the same element have the same chemical behavior?
Chemical properties of a element is governed by ELECTRONIC CONFIGURATION of that element. As isotopes of same element have identical electronic configurations, their chemical properties are same.
How do isotopes differ from the natural form of an atom?
All forms of all atoms, both natural and man made, are isotopes. Different isotopes of the same element merely have more or less neutrons than the average atomic weight would indicate. The atomic number shows how many electrons are in the outer shell and also how many protons are in the nucleus of every isotope of any specific element.
What is the dot diagram for boron?
The electron dot diagram for boron shows three dots, representing the three valence electrons in the outer shell of a boron atom. These dots are positioned singularly on each side of the boron symbol.
How do radioactive isotopes check the circulation of blood into the bloodstream?
The isotopes don't check the circulation. But the isotopes can be picked up on a scan, and if that scan shows isotopes going everywhere then that means that the blood is also going everywhere.
What is the positions of electrically charged pith balls?
A person will not know which of the following illustrations of electrically charged pith ball shows the correct position of the pith balls without seeing the illustrations. It is important to include the illustrations as well.
How does the discovery of isotopes contradict Dalton's theory?
It was then changed to "All atoms of the same element contain the same number of protons and electrons, but atoms of a given element may have different numbers of neutrons." after James Chadwick discovered that the nuclei of most atoms contain neutrons as well as protons.
What is one element a topographic map shows?
it shows where to go
What symptom in snake gourd plant may appear if there is boron deficiency?
A snake like an python. Usually boron deficiency shows up as a brown rot in the centre of the gourd or root crop.
The substance whose Lewis structure shows three covalent bonds is?
Boron is an example of a substance whose Lewis structure shows three covalent bonds. In its Lewis structure, boron typically forms three single bonds with other atoms.
Why do elements which exists as isotopes have fractional atomic mass?
Each isotope of an element has a different Atomic Mass, so an average is taken of all the isotopes, but the average is weighted because the natural abundance (%) of each isotope is factored in. If hydrogen-1 is much more abundant than deuterium and tritium, then the weighted average will be closer to 1 than 2 or 3 but not a whole number. The following equation shows how percent abundance factors into the weighted average. (atomic mass A)(X% abundance) + (atomic mass B)(Y% abundance)...=(weighted average of all isotopes of the element)(100% abundance)
