What element contains 8 protons 8 neutrons and 8 electrons?
What element contains 8 protons 8 neutrons and 8 electrons?
oxygen
An oxygen atom usually has 8 protons, 8 neutrons, and 8 electrons. Looking at the periodic table, oxygen has atomic number 8 and atomic weight 15.999.
How many neutrons does lithium 8 have?
Unstable known isotopes of lithium include Lithium 8 (5 neutrons), Lithium 9 (6 neutrons), lithium 11 (8 neutrons) and lithium 4 (one neutron). Masters in Chemistry specializing in preparing for ACT Science. Lithium is the third element in the Periodic Table with an atomic number of 3 and an atomic mass of 6.941.
How many protons and neutrons does lithium 8 have?
There are 3 protons (so obviously 3 electrons) and 4 neutrons. Lithium-7 is the most abundant form of lithium.
Does lithium have 8 electrons?
Shell number one can only hold 2 electrons, shell two can hold 8, and for the first eighteen elements shell three can hold a maximum of eight electrons. That means there are 3 electrons in a lithium atom.
What element has 8 protons in each atom?
Oxygen
Oxygen is a chemical element – a substance that contains only one type of atom. Its official chemical symbol is O, and its atomic number is 8, which means that an oxygen atom has eight protons in its nucleus.
What element has 8 protons 8 electrons and 11 neutrons?
Explanation: Well, the atom will 8 protons is oxygen, as seen on the periodic table.
How many protons are in the isotope lithium 8?
Notice that because the lithium atom always has 3 protons, the atomic number for lithium is always 3. The mass number, however, is 6 in the isotope with 3 neutrons, and 7 in the isotope with 4 neutrons.
How many protons does lithium have?

What atom has 8 protons 8 electrons and 9 Neutrons?
8 17 This isotope of oxygen has 8 protons (atomic number), 8 electrons and 9 neutrons. (Recall that mass number is the total of protons and neutrons. ) Isotopes are also often written as C-12 C-13 C-14 The number is the mass number.
What atom has 8 protons 8 neutrons and 10 electrons?
16O2− has 8 protons, 8 neutrons, and 10 electrons.
How many protons are in lithium?
Lithium, a member of the alkali metals , has three protons, three electrons and four neutrons. It has an atomic weight of 6.941 atomic mass units and is a solid at room temperature. Li is the abbreviation for lithium, and its name comes from “lithos,” the Greek word for stone.
How to find the number of protons, neutrons, and electrons?
Get a periodic table of elements. The periodic table is a chart that organizes elements by their atomic structure.
What is the mass number of lithium?
Lithium’s mass number is 7. This is because Lithium has 3 protons and 4 neutrons. 9 people found this useful.
What is the atomic mass of lithium?
Naturally occurring lithium contains two isotopes. The common one has an atomic mass of 7. About one per cent of the lithium has an atomic mass of 6. The atomic mass of Lithium-Li is 6.941 grams.
