How many neutrons does lithium 8 have?
How many neutrons does lithium 8 have?
An isotope of lithium is a specific type of lithium . For example, you can have lithium-6, which has 3 neutron. Lithium-7 would have 4 neutrons, lithium-8 would have 5 neutrons and so on.
How many protons and neutrons does lithium 8 have?
Lithium, by definition, has 3 protons. If the atom is neutral, uncharged, it will have 3 electrons. There are two naturally occurring isotopes of lithium, lithium-6 with 3 neutrons and lithium-7 with 4 neutrons.
How many protons does lithium 8 have?
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.
What element has 8 protons 8 neutrons and 2 electrons?
Oxygen is atomic number 8 on the periodic table, which means it has 8 protons!
How many protons neutrons and electrons do lithium?
Lithium is an alkali metal with the atomic number = 3 and an atomic mass of 6.941 g/mol. This means that lithium has 3 protons, 3 electrons and 4 neutrons (6.941 – 3 = ~4). Being an alkali metal, lithium is a soft, flammable, and highly reactive metal that tends to form hydroxides.
How many protons and neutrons does carbon 14 have?
For example, carbon-14 is a radioactive isotope of carbon that has six protons and eight neutrons in its nucleus. We call it carbon-14 because the total number of protons and neutrons in the nucleus, also known as the mass number, adds up to 14 (6+8=14).
How many protons are in Carbon?
Every carbon atom has six protons, and the majority of carbon atoms have six neutrons. A carbon-12 atom has 6 protons (6P) and 6 neutrons (6N). But some types of carbon have more than six neutrons. We call forms of elements that have a different number of neutrons, isotopes.
How many protons neutrons and electrons does ca2+ have?
Ca2+ represents an ion with 20 protons and 18 electrons. A calcium atom has 20 protons and 20 electrons. The 2+ charge next to the symbol indicates a loss of two electrons: 20-2=18. When atoms form ions, they lose or gain electrons.
How many protons and electrons does lithium have?
Lithium is an alkali metal with the atomic number = 3 and an atomic mass of 6.941 g/mol. This means that lithium has 3 protons, 3 electrons and 4 neutrons (6.941 – 3 = ~4).
What atom has 8 electrons 8 protons and 8 neutrons?
Oxygen has eight protons, eight neutrons, and eight electrons. Oxygen is different from carbon because it has more particles. Each kind of atom has a different number of the three particles. Protons and neutrons are in the center, or nucleus, of the atom.
What element has 8 protons 8 neutrons 8 electrons?
The oxygen atom has therefore 8 neutrons, 8 protons and 8 electrons.
Why are there 4 neutrons in lithium?
A lithium atom contains 3 protons in its nucleus. Notice that because the lithium atom always has 3 protons, the atomic number for lithium is always Z = 3. The mass number, however, is A = 6 for the isotope with 3 neutrons, and A = 7 for the isotope with 4 neutrons.
What is the number of neutrons in lithium?
Lithium has a total of four neutrons. The element also has an atomic number of 3 and an atomic weight of 6.94. It is found in the alkali metal group on the periodic table and has the chemical symbol of Li. Lithium is a silver-colored element that also includes three protons and three electrons.
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.
How do you calculate the number of protons and neutrons?
The number of neutrons can be calculated by subtracting the number of protons from the atomic mass, which is 16 minus eight for oxygen.An atom is primarily comprised of neutrons, electrons and protons. The neutrons and protons are contained within the nucleus, a tight central area of the atom.
What is the main difference between protons and neutrons?
Protons have a much smaller mass than neutrons. Protons have a much larger volume than neutrons. Protons have an electrical charge, but neutrons have no charge. Protons make up the nucleus, but neutrons orbit around the nucleus. to add a comment.
