What element has 5 proton 5electrons and 5 neutrons?
Boron
What element has 4 electrons 5 protons and 4 neutrons?
Be- Beryllium
What is the atomic mass of an element with 4 protons 5 neutrons and 4 electrons?
The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus. In this case, the element has 4 protons and 5 neutrons, so its atomic mass is 4 + 5 = 9 atomic mass units (amu). The number of electrons does not affect the atomic mass.
How would you describe the isotopes of hydrogen?
All atoms of a specific element have the same number of protons in their nucleus, but the number of neutrons in the nucleus may vary these are isotopes of that element.Hydrogen has several possible isotopes, only the first three of these are commonly referred to:hydrogen or protium or hydrogen-1, 1 proton 0 neutrons, stabledeuterium or hydrogen-2, 1 proton 1 neutron, stabletritium or hydrogen-3, 1 proton 2 neutrons, radioactive halflife 12.26 yearshydrogen-4, 1 proton 3 neutrons, radioactive halflife about 139 yoctosecondshydrogen-5, 1 proton 4 neutrons, radioactive halflife about 910 yoctosecondshydrogen-6, 1 proton 5 neutrons, radioactive halflife 290 yoctosecondshydrogen-7, 1 proton 6 neutrons, radioactive halflife 23 yoctosecondsetc.
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 element has 5 neutrons 4 protons?
Beryllium
If a lithium atom contains 3 protons 4 neuthrons and 3 electrons what would be formed if one proton is added to this atom?
Beryllium has 4 protons, 5 neutrons, and 4 electrons
What element has 4 protrons 5 neutrons and 4 electrons?
Any atom with 4 protons is an atom of beryllium. If the atom is neutral, it must also have 4 electrons. However, 5 neutrons specifies an isotope, specifically Be-9, rather than an element as such.
What is the atomic number of an atom that has a mass of 9 and 5 neutrons?
The mass is protons + neutrons. So, if the mass is 9 and it has 5 neutrons, then there must be FOUR (4) protons. This would be the element beryllium (Be).
A lithium atom contains 3 protons 4 neutrons and 3 electrons. What would be formed if one proton is added to this atom?
As you already know the atom consists of protons, neutron and eletrons. The number of protons determins which chemical element it is, and on the periodic table of elements, we can see that the next element after lithium is beryllium.-An atom with 3 protons, 3 neutrons, and 3 electrons.- An atom with 3 protons, 5 neutrons, and 3 electrons
What is the metalloid element with the fewest number of protons?
If you look at the periodic table, the atomic number denotes the number of protons in the element. For example, the first element on the table is hydrogen, and it has one proton (the fewest). Element number two is helium, and it has two protons, etc.
What element in the periodic table has 4 neutrons?
Any element can have 4 neutrons but most of them aren't metallic. Anyway's on the periodic table it would be Be and that stands for Beryllium
