The Li ion is different from the atom because it has positive charge. (Lithium is group 1 element and these lose 1 electron to form for example :Li+ , Na+ etc)

Why is water a molecule rather than an atom?
Water is a molecule rather than an atom because it consists of more than one atom. In fact it consists of atoms of two different elements.
Is magnesium more reactive than lithium?
Lithium is more reactive to water than magnesium because while Lithium will explode and generally destroy the container it is in, magnesium will cause the water to violently bubble.
What is the difference in the number of protons and electrons in an atom?
The number of protons (each has charge = +1) in an atom identify the element, e.g. hydrogen (1 proton), helium (2 protons), etc. If the number of electrons is the same, then the atom is neutral (total charge = 0). For example, a lithium atom has three protons in the nucleus (charge = +3) and three electrons (charges -1,-1,-1). The total charge is +3 -1 -1 -1 = 0. If the number of electrons is different than the number of protons, as when lithium would lose an electron, we say the lithium atom has been ionized--it is now a lithium ion and the charge is +3 -1 -1 = +1. If the lithium ion loses another electron, we would say it is doubly ionized or twice ionized and the charge would be +3 -1 = +2.
How is helium gas different than lithium metal?
An atom of lithium has 3 protons in its nucleus, which means 3 electrons in the atom. An atom of carbon has 6 protons in its nucleus, which means 6 electrons in the atom. The number of electrons is what gives an element its characteristic chemical properties.
Why conductivity of lithium is less than cesium?
The conductivity of lithium is less than cesium because lithium has smaller atomic size and higher ionization energy compared to cesium. This results in weaker metallic bonding and less mobile charge carriers in the lattice structure of lithium, leading to lower conductivity. Additionally, lithium also has a higher tendency to form covalent bonds, which further reduces its conductivity.
Is the lithium atom bigger than the Cesium atom?
Not at all; the cesium atom is far bigger than the lithium atom.
Does a boron atom have less protons than a lithium atom?
Boron has more protons. It has 5, lithium has 3.
Does the boron atom has fewer or more electrons than lithium atom?
fewer
Why is an iron atom a different element than a sodium atom?
An iron atom is a different element than a sodium atom because it has a different ground state electron configuration. In fact, any atom that differs from any other atom in ground state electron configuration is a different element.
Why is a lithium ion less reactive than a lithium atom?
Let me start off by saying that the Lithium ion is not less reactive than the Lithium atom. In fact, Li+ is far more reactive than the Lithium atom, which is why it does not exist in its free state. Lithium ions tend to combine with anything it comes into contact with. However, it has a more stable electronic configuration than the Lithium atom, resembling that of a Noble gas(in the case of Li, it is Helium), which is why 1+ is the preferable oxidation state of Lithium.
Compare the stability of a lithium atom with that of its ion Li plus?
Li+ means that the atom lost an electron. And this means it has now has a complete outershell, thus being more stable than the Lithium atom with 1 valence electron
Compare the stability of a lithium atom with that of its ion Li plus .?
Li+ means that the atom lost an electron. And this means it has now has a complete outershell, thus being more stable than the Lithium atom with 1 valence electron
Why is it easier to lose electrons from a cesium atom than from a lithium atom?
It all has to due with ionization energy. Ionization energy is the energy required to remove an electron from an atom to make it an ion. Cesium has a lower ionization energy than Lithium, so it is easier to remove electrons, and thus lose electrons, from a Cesium atom than a Lithium atom.
Is Li plus smaller than Li?
An Na atom is larger as it has one more shell carrying an extra electron that it has not donated yet . In the case of Na (ion) it has lost or donated an electron which means it no longer has the shell that carried the last electron.
Why is water a molecule rather than an atom?
Water is a molecule rather than an atom because it consists of more than one atom. In fact it consists of atoms of two different elements.
Why does lithium have a smaller atomic radius then potassium?
because the second ionisation means removing the second electron from the potassium atom. Potassium only has one electrin in its outer most shell so the second electron would be in another electron shell which is closer to the nucleus meaning there is a stronger attraction to that electron because of the protons in the nucleus which are positive and attrct the negative electrons so more energy is needed to remove the second electron
What element has the most protons calcium gold lithium or oxygen?
Gold has the most protons per atom, because it has a higher atomic number than any of the other elements listed.
