What element has 4 protons 4 neutrons and 3 electrons?
Beryllium To figure this out: The atomic number of an element is the number of protons the element has in the nucleus. Using this knowledge you can figure out which element has the atomic number of four, which in this case is Beryllium.
What element has only 4 neutrons in the nucleus and is metallic?
your mother
What is the Bohr model for Lithium?
Lithium is element number 3Its nucleus contains 3 protons and 4 neutrons (Atomic Mass=7) and there are 3 electrons in orbit around the nucleus.Since there can be only 2 electrons in any orbit. the third electron orbits in a second orbital path, further out from the nucleus.
Helium-4 and helium-3 are?
isotopesHelium-4 and helium 3 are isotopes and each have 2 protons. Helium 3 only has 1 neutron, while helium 4 has 2 neutrons.
What is the element 28?
The element with atomic number 28 is Nickel (Ni). It is a transition metal in period 4 of the Periodic Table. It is the first element in the Nickel family. It has 28 electrons in 4 shells with 2 electrons in the outer shell.
What particle has 2 neutrons and 2 protrons in its nucleus?
It could be either an alpha particle or a He-4 isotope.
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 element has 12 alpha particles and 4 neutrons?
Mathematically it is Chromium 24Cr52 but within nucleus alpha particles separately do not exist they are only produced during radioactive disintegration.
When a nucleus undergoes nuclear decay by gamma rays the atomic number of the element?
nothing, the nucleus just relaxes to a lower energy state that is more stable
What element has 4 protons 4 neutrons and 3 electrons?
Beryllium To figure this out: The atomic number of an element is the number of protons the element has in the nucleus. Using this knowledge you can figure out which element has the atomic number of four, which in this case is Beryllium.
What is the difference between helium-4 and helium-3?
The main difference between helium-4 and helium-3 is in their atomic structure. Helium-4 has two protons and two neutrons in its nucleus, while helium-3 has two protons and only one neutron. This difference in atomic composition leads to distinct physical properties and behaviors in these two isotopes.
When an alpha particle is emitted the nucleus of the original element?
An alpha particle is a helium-4 nucleus, and contains two protons and two neutrons. Therefore, the original nucleus will have two protons and two neutrons less. Its atomic number will be two less, and its atomic mass will be 4 less.
What is the element formed during aplha decay?
The element formed during alpha decay is a new element with an atomic number that is 2 less and an atomic mass that is 4 less than the original element. An alpha particle, which consists of 2 protons and 2 neutrons, is emitted during the process.
How many 5-element DNA sequence contain only A and T?
4^4
What is the charge of Lead II?
A cation is any element with a positive charge. Lead most commonly forms an anion, which means it has a negative charge. But any element can have any charge, but only under certain condistions
What element has only 4 neutrons in the nucleus and is metallic?
your mother
What is the atomic mass of an element with 4 protons 5 neutrons and 4 electrons?
4 protons 4 electrons 5 neutrons subtract the number of of protons from the atomic weight
