What is the number of electrons and neutrons for lithium?
The number of protons will always be 3 in each Li atom, and either 3 or 4 neutrons, depending on the Li atom's isotope. 6Li has 3 protons, while 7Li has 4. All other isotopes of Lithium are unstable.
How many protons and neutrons does Li-9 have?
Lithium-9 has exactly 3 protons, 3 electrons, and 6 neutrons. To Find the number of protons just look on your periodic table, the number usually above the element on the table or the number in bold. (3) Finding the number of neutrons is simply the number preceeding the name (9) minus the number of protons (3).
What is the element number of lithium?
The atomic number of lithium (Li) is 3. The atomic weight of Li is 6.941 amu, and the molar mass 6.941 grams per mole. See the Web Links to the left of this answer for a periodic table with more information about this element!
What is the symbol of barium and number of neutrons?
The symbol is Ba. The number of neutrons equal the number of protons.
How do you calculate the number of neutrons in cobalt?
The number of neutrons in any element is equal to mass number - atomic number. So,number of neutrons in cobalt is = 58 - 27 = 32. therefore, number of neutrons in cobalt is 32.
How many neutrons are there in this lithium ion?
Li-6 has 3 neutrons and Li-7 has 4 neutrons.
How many neutrons are there in lithium ion?
Li-6 has 3 neutrons and Li-7 has 4 neutrons.
What am I have 4 neutrons and I am metallic what am I?
7Li or lithium-7.The mass number of an isotope is the sum of the protons and neutrons in its atomic nuclei. The atomic number of Li is 3, so lithium-7 would have 3 protons and four neutrons.
What is the number of electrons and neutrons for lithium?

What is the total number of neutrons in an atom of 7 lithium 3?
The atomic number of lithium is 3, which means that there are three protons. The number of neutrons depends on the mass number of the particular lithium isotope. Mass number is the SUM of the protons and neutrons. An atomic number of 3 and a mass number of 7 means that there are three protons and four neutrons. Lithium has two stable isotopes, Li-6 and Li-7 which means that there are 3 or 4 neutrons, respectively. The atomic number of lithium is 3, which means that there are three protons. The number of neutrons depends on the mass number of the particular lithium isotope. Mass number is the SUM of the protons and neutrons. An atomic number of 3 and a mass number of 7 means that there are three protons and four neutrons. Lithium has two stable isotopes, Li-6 and Li-7 which means that there are 3 or 4 neutrons, respectively.
How many does Neutrons does Li?
The most frequent isotope of lithium has 4 neutrons.
How many protons and neutrons does Li-9 have?
Lithium-9 has exactly 3 protons, 3 electrons, and 6 neutrons. To Find the number of protons just look on your periodic table, the number usually above the element on the table or the number in bold. (3) Finding the number of neutrons is simply the number preceeding the name (9) minus the number of protons (3).
How many protons neutrons and electrons does Li have?
The most frequent isotope of lithium has 4 neutrons.
Which symbols represent atoms of the same element that are istopes?
The normal chemical symbol is used for the isotope with the addition of the atomic number (Z) at the lower left of the symbol and the atomic mass number (A) at the upper left as shown X.For example Li and Li represent two isotopes of lithium.Since all lithium isotopes have an atomic number Z=3, this number is usually omitted and the isotopes are represented by the symbols Li and Li. These are sometimes written as Lithium-6 and Lithium-7 or Li-6 and Li-7.
The Li atom will have how many neutrons?
The atomic mass of Lithium is 6.941. Its has 3 protons and the most common has 4 neutrons.
