An element has 4 protons 5 neutrons and 4 electrons What is the atomic mass of the element?
That would Beryllium, with an atomic number of 4 and mass number of 9Hope this helped!
What is atomic weight of tungsten?
The atomic number of tungsten (W) is 74.The atomic weight of W is 183.84 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!
Which element contains five electrons in its 3D orbital?
The element that contains five electrons in its 3d orbital is manganese (Mn). Manganese has an atomic number of 25, and its electron configuration is [Ar] 4s² 3d⁵. This means it has five electrons in the 3d subshell.
What are different atomic forms of an element?
An element can exist in different atomic forms known as isotopes, which have the same number of protons but different numbers of neutrons. For example, carbon has isotopes like carbon-12 and carbon-14. Additionally, an element can form ions by gaining or losing electrons, resulting in charged particles with different electron configurations.
How does an isotope differ from a normal atom?
When an atom is of the same atomic number, atomic mass, etc. to the one on the periodic table (Lets use Boron for example) Then B is the regular atom. But if you change the number of nuetrons (from 6-to-7 or whatever number) ; because the number of protons never changes; you will get a different atomic mass, so an isotope is the atom with a different atomic mass. You write an isotope atom with the elements symbol and to the left of it you script (In the top left corner really small like an exponent) the new atomic mass. So in this case B would now be 12B. (except scripted, but I sadfully forgot how to do that on a computer....)
An element has 4 protons 5 neutrons and 4 electrons What is the atomic mass of the element?
That would Beryllium, with an atomic number of 4 and mass number of 9Hope this helped!
Which element has 5 protons 7 neutrons 5 electrons and a mass of 12?
The element with 5 protons and 7 neutrons would be Boron (atomic number 5). However, the element also having 5 electrons doesn't match the standard atomic structure, so it could be an ionized form of Boron.
How many electrons are in the outer shell of an atom with the atomic number of five?
Atoms with atomic number five have five electrons. Since the atomic number represents the number of protons, which is equal to the number of electrons in a neutral atom, there are five electrons in the outer shell as well.
What can be determined if you know the atomic number of an electrically neutral atom?
The number of electrons can be determined if the overall charge and number of protons are known. If the charge of an atom is neutral, then how ever many protons it has it will also have that number of electrons.
What is the identity of an element with 5 protons 7 neutrons and 5 electrons?
Five protons makes this the element boron. The number of protons is the atomic number, and determines the identity of an element. This example would be the boron-12 isotope because it contains 5 protons and 7 neutrons.
If the number of electrons in a natural atom is thirty five and its mass number is eighty what is the number of protons?
The number of protons is the atomic number
What element has four protons four electrons and five neutrons?
There are too many electrons. This would be a negative ion of lithium-6 (stable but less common isotope) that does not occur naturally. The element with 3 electrons, 3 protons, and *4 neutrons* is lithium-7, the most common isotope. It forms a stable positive ion (2 electrons).
How many protons neutrons and electrons are in Bi?
Five proton and electrons, 6 neutrons. This because this is the atomic number of boron, which states how many protons and electron in the element. For neutrons you must subtract the atomic number (5 in this case) from the rounded. average atomic mass.
Which element on the periodic table has an atomic number five?
Boron.
If an atom of tin has a mass number of 118 and an atomic number of 50 how many neutrons are in its nucleus?
AnswerProtons = 4Neutrons = 5There are four protons, four electrons, and five neutrons.You can find the number of protons by looking and the atomic number, and because this atom is not an ion (a charged atom), the number of protons and electrons are equal.You can find the number of neutrons by subtracting the number of the protons from the atomic mass. In this case, 9 minus 4 equals 5 for the number of neutrons. Your atom is the element beryllium, and is specifically the one stable isotope of that element, 9Be.
What element has a mass number of 10?
A mass number of 10 means the total of protons and neutrons is 10. It can be either:Boron-10 has five protons and five neutrons but also can have 6 neutrons.Beryllium-10 has four protons and six neutrons. It is very rare and decays to boron-10. Beryllium-9 is much more common with four protons and fiveneutrons.
What are the 5 properties to identify an element?
Atomic number: Number of protons in the nucleus. Atomic mass: Average mass of the element's isotopes. Valence electrons: Number of electrons in the outermost energy level. Electron configuration: Arrangement of electrons in energy levels. Chemical reactivity: How the element interacts with other elements.
