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.

∙ 11y agoHelium is a gas with two protons, two electrons. It has completely filled s orbital. It is chemically inert.
Lithium is a metal with three protons, three electrons. It has one valence electron and is generally reactive.
Wiki User
∙ 6y agoAn ion of any element has a nonzero electric charge while the "normal" atoms of the same element have zero electric charge. Atoms become ions either by losing electrons or by gaining electrons.
Lithium (being on the left side of the Periodic Table) will usually tend to lose electrons, becoming positively charged.

∙ 9y ago- the atomic number of carbon is 6 and the atomic number of uranium is 92
- carbon has 2 stable isotopes; uranium has only unstable, radioactive isotopes
- uranium has fissile or fertile isotopes; carbon hasn't
- the electron configuration is very different
- the atomic radii are very different
- the atomic weights are very different
etc.

Which is softest sodium or lithium?
sodium is a softer metal than lithium.
Why does lithium metal conduct electricity well where as sold lithium chloride does not?
Lithium chloride is a completely different substance than lithium metal. Sodium chloride is table salt however table salt isn't highly corrosive or explosive in water. Properties can change dramatically when compounds are formed.
What is big bang necleosynthesis?
Nucleosynthesis. It refers to the formation of atoms larger than Helium-1. Because of the extreme conditions right after the Big Bang, it is believed that some Deuterium and Helium were formed, perhaps some Lithium too; but no significant amounts of other metals. (In Astronomy, a metal is any element heavier than Helium.)
What alkali metal with fewer than 10 protons in the necleus?
Lithium.
What alkali metal element is less reactive than calcium?
it is the lithium metal. it is less reactivated.
Is lithium a pure element?
No - the lightest elements are hydrogen and helium. Although lithium is a lightest metal and the lightest element that is a solid at room temperature.
Which is softest sodium or lithium?
sodium is a softer metal than lithium.
Why does lithium have a higher first ionisation energy than helium?
Helium has a higher ionization energy than in lithium. Further, helium has the highest first ionization energy in all the elements in the periodic table. Lithium has an electronic configuration of [He]2s1. The outer electron is further out and experiences a lower effective nuclear charge. The 2s electron is further out from the nucleus than the 1s electrons in He. Lithium has an atomic radius of 152pm, whereas helium is calculated at 81pm. The effective nuclear charge on the helium electrons is higher than that acting on the 2s electron in Lithium. Estimates vary a little but roughly for helium it is .69 units. For Lithium the effective nuclear charge is 1.3 due to the "shielding" caused by the inner 1s electrons.

Which is more reactive lithium in group 1 or neon in group 18?
neon is a noble gas that will not react with anything -- any other element except helium is more reactive than neon! With lithium, quite a reactive metal, it is certainly more reactive than neon.
What is big bang necleosynthesis?

Because of the extreme conditions right after the Big Bang, it is believed that some Deuterium and Helium were formed, perhaps some Lithium too; but no significant amounts of other metals.

What alkali metal with fewer than 10 protons in the necleus?
Lithium.
Can lithium melt?
Everything can conduct heat except a vacuum. Lithium is a metal so it should do better than most.
Is lithium less dense than water?
Technicaly, its lighter than oxigen, nitrogen, and all the other gasses, (i believe) exept hydrogen and helium. so yes, i SOULD be lighter than air, but if you let go of it, it will fall. but it is the lightest metal. So in conclusion, i should be lighter than air, but.isn't. how interesting!
What is the difference between helium and iron?
Helium is a gas that is lighter than air. Iron is a solid metal and is heavy.
Is there anything lighter than oxygen?
In fact there are seven elements lighter than oxygen: hydrogen, helium, lithium, beryllium, boron, carbon and nitrogen.
What are other differences between lithium and helium?
Helium has an atomic mass of 4.- Number of Protons/Electrons: 2- Number of Neutrons: 2Lithium has an atomic mass of 7.- Number of Protons/Electrons: 3- Number of Neutrons: 4Helium has TWO less neutrons than Lithium.
