For instance, lithium exists as an isotope with 3 neutrons, and as an isotope with 4 neutrons, but it doesn’t exist as an isotope with 2 neutrons or as an isotope with 5 neutrons.
Similarly, What elements has 4 valence electrons?
Carbon and silicon BOTH come from Group 14 of the Periodic Table , i.e. both formally have the same number of valence electrons, 4 such electrons………
Additionally, How many neutrons are in lithium 4? Lithium-4. Lithium-4 contains three protons and one neutron.
How many neutrons does lithium have?
A lithium atom is an atom of the chemical element lithium. Lithium is composed of three electrons bound by the electromagnetic force to a nucleus containing three protons along with either three or four neutrons, depending on the isotope, held together by the strong force.
Which isotope of lithium has 3 neutrons?
The two stable isotopes of lithium are Lithium 6 with three neutrons and lithium 7 with four neutrons. Lithium 7 is the predominant isotope, about 92.5%.
Does tin have 4 valence electrons?
Tin is located in the group 14 of the periodic table, which means that it has four electrons in its outermost shell, i.e. four valence electrons.
Does carbon have 4 valence electrons?
Atomic carbon has six electrons: two inner shell (core) electrons in the 1s orbital, and four valence (outer most shell) electrons in the 2s and 2p orbitals.
Does sulfur have 4 valence electrons?
Explanation: Sulfur has six valence electrons. Valence electrons are the outermost electrons which, therefore, are located on the highest energy levels. Consequently, these are the electrons available for chemical bonding.
How many electrons are in a Li+ ion?
However, in this question we are being asked the electrons in a lithium ion. Lithium, as a metal, donates electrons and so must have lost an ion in order to have a +1 charge. Therefore, the number of electrons must be 2.
How many electrons does 19f1 have?
There are 9 electrons.
How many neutrons protons and electrons are in 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.
What element has 18 protons and 22 neutrons?
Given the number of protons is [18]. So, the atomic number is also [18], and the element with atomic number [18] is Argon with the symbol [Ar]. Now we need to find the mass number of Argon. Since, a neutral atom of argon also has 22 Neutrons.
How many electrons do lithium have?
A lithium atom, for example, has three electrons. It has two in the first shell and one in the second shell.
How many neutrons does Li-6 have?
Lithium-6 has 3 protons (as it must if it is to be the element Lithium) but only 3 neutrons, so it has a mass number of 6.
Which of the following represents an isotope for lithium 7 3 Li )?
Lithium-7 atom is the stable isotope of lithium with relative atomic mass 7.016004, 92.5 atom percent natural abundance and nuclear spin 3/2. An element in the alkali metals family. It has the atomic symbol Li, atomic number 3, and atomic weight [6.938; 6.997].

How many isotopes does lithium have?
Lithium has two stable isotopes Li-6 and Li-7, the latter being 92.5% in nature (hence relative atomic mass of natural lithium of 6.94).
Why does Sn have 4 valence electrons?
The quick answer here is that because tin, Sn , is a main-group element, the number of valance electrons will be given by its group number. Tin is located in group 14 of the periodic table, which means that it has 4 electrons in its outermost shell, i.e. 4 valence electrons.
Does carbon have 4 or 8 valence electrons?
Explanation: The octet rule states that atoms can fill their outer shells with up to 8 electrons (a full shell of 8 is the most stable configuration). Since Carbon only has 4 of its outer electron slots (or valence electrons) full, it has room to make bonds with 4 other atoms, assuming they are all single bonds.
Does carbon have 4 or 6 valence electrons?
There are 4 valance electrons in Carbon.
How many valence electrons does sulfur?
The superscripts associated with these orbitals total to 6. Therefore, sulfur has 6 valence electrons.
How many valence electrons does sulfur have?
Sulfur has 6 valence electrons located in its outermost orbit. When looking at the sulfur atom, it contains 16 total electrons.
How many valence electrons does sulfur s have?
Answer: Sulfur has 6 valence electrons because it is in Group 16. Remember, don’t confuse valence electrons with total electrons!
How many protons and electrons are in the Li+ ion?
Lithium atom has electron arrangement 2,1 and the Li+ ion will be 2. So 7/3 Li+ has 3 protons, 4 neutrons and 2 electrons.
What ion is Li+?
Lithium ion | Li+ – PubChem.
What is the electron configuration of a Li+ ion?
Therefore it is having an atomic number of 3. the first two electrons occupies in the 1s orbital. The orbital can hold 2 electrons the remaining electron for Li goes in the 2s orbital. Therefore the Li electron configuration will be 1s22s1.
