It is lithium(Li) .
NB Most elements produce isotopes.
Hydrogen has 3 isotopes.
Carbon has 3 isotopes
Chlorine has 2 isotopes.
To name but a few.
If the atom has 3 protons, it is lithium regardless of the number of neutrons.
This can only be one isotope, 7Li, which makes up 92 to 96% of lithium on Earth.
a neutral atom (of lithium)
or
one of the isotopes of the element lithium
The number of protons, which is the atomic number, tells you the identity of the element. In this case, the element with 3 protons, and therefore atomic number 3, is lithium.
The more protons and neutrons that are in the element and isotope electrons are negligible in terms of mass.
Mass number = number of protons + number of neutrons Number of electrons = number of protons = mass number of an isotope - number of neutrons
To know the element, you need only know how many protons it has. All atoms of carbon have 6 protons. Carbon-12 is an isotope of carbon that has 6 protons and 6 neutrons.
Protons = 92 Electrons = 92 Neutrons = 146 The number of electrons and protons in a neutral atom are each equal to the atomic number of the element (92). The number of neutrons equals the atomic weight minus the number of protons (238 - 92 = 146).Uranium has 92 protons, 92 electrons, and usually 147 neutrons, though another isotope has 143 neutrons.
Yes, the isotope potassium-39 has 20 neutrons.
An isotope is an element with the same number of electrons and protons different number of neutrons.
It is normal for the isotope of the element helium. 2He4 isotope has 2 protons, 2 neutrons and 2 electrons.
Americium has 95 protons and electrons. Number of neutrons: atomic mass of an isotope - number of protons
The element is krypton as it has 36 protons and the isotope is 36Kr86.
The element is Neon and the isotope is 10Ne19
titanium
Californium has 98 protons and neutrons.For each isotope the number of neutrons is different.Number of neutrons = Mass number of an isotope - 98
The element is Neon and the isotope is 10Ne19
The isotope 7N15
leadLead but it has 82 protons and electrons and 125 neutronshope i helpedLead 125, with a -4 chargeradon
Zinc has 30 electrons, 30 protons and 34 neutrons.
The mass of the isotope 7Be is 7,01692983(11) u. The isotope 7Be has 4 protons, 3 neutrons and 4 electrons (not 6).
