What is the atomic number and the atomic mass of lithium?
Hydrogen has 1 as its atomic number. That's because it has one proton in its nucleus. Hydrogen has three isotopes. Each isotope has one proton in its nucleus (naturally, because that's what makes it hydrogen). Atomic mass is the number of protons plus the number of neutrons in an atom's nucleus. Let's look at each isotope of hydrogen. "Simple" hydrogen has only the 1 proton in its nucleus. It's atomic number is 1 and its mass number is 1 (the 1 proton plus zero neutrons). Heavy hydrogen has 1 proton and 1 neutron in its nucleus. It's atomic number is 1 and its mass number is 2 (the 1 proton plus 1 neutron). Heavy, heavy hydrogen has 1 proton and 2 neutrons in its nucleus. It's atomic number is 1 and its mass number is 3 (the 1 proton plus 2 neutrons).
When a lithium atom forms a Li plus ion the lithium atom does what?
THe lithoium atom has IONISED ( lost) an electron, to become the lithium ION.
In the process of nuclear fusion four hydrogen nuclei fuse to form a nucleus of what?
A helium nucleus plus energy released. see the link below
How many valence electrons does the element Li have?
They do not. Helium has two electrons in its valence shell. Neon has eight, plus two more beneath the valence shell. However, since the first energy level can only hold two electrons, helium has a full valence shell, which explains why its properties are similar to those of neon.
What does 2 hydrogen atoms plus 1 oxygen atom equal?
2 hydrogen atoms plus 1 oxygen atom combine to form a molecule of water (H2O).
What elements where in the big bang?
At first, there were none. Once the Universe cooled down enough (after 3 minutes or so), hydrogen and helium formed - plus a very small amount of lithium.
What is hydrogen plus lithium plus Beryllium?
When hydrogen, lithium, and beryllium atoms combine, they form a molecule with the chemical formula LiHBe. This molecule would have a unique set of properties based on the different characteristics of each element.
What elements are in this unbalanced chemical reaction Li plus H2O LiOH plus H2?
lithium, hydrogen, oxygen
H H L B B C N O What is the next two answers plus the explanation to this pattern?
HHLBBCNOFNSMASP The first letters of each of the elements. hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen...
Hydrogen plus hydrogen helium?
When two hydrogen atoms react, they can combine to form helium through nuclear fusion. This process releases a tremendous amount of energy and is the basis for the power source of the sun and other stars.
Equation for the reaction Lithium plus hydrochloric acid yields lithium chloride plus hydrogen?
The balanced chemical equation for this reaction is: 2Li + 2HCl → 2LiCl + H2. This equation shows that two moles of lithium react with two moles of hydrochloric acid to produce two moles of lithium chloride and one mole of hydrogen gas.
How is the atmosphere of Uranus different from that of Saturn?
Uranus has more hydrogen and less helium than Saturn, but both atmospheres are similar.Saturn's atmosphere: Hydrogen 75%, Helium 25%, plus tiny amounts of other gases.Uranus' atmosphere: Hydrogen 83%, Helium 15%, Methane 2% plus tiny amounts of other gases (acetylene and hydrocarbons).That uranus atmosphere is smaller and saturn's is biger
What symbol for the ion is formed if lithium loses 1 electron?
ok so you'll notice that lithium is on the second row of the periodic table, this means that its the next orbital hydrogen = 1s1 orbital helium = 2s1 orbital lithium = 2s1, 1s2 orbital removing the outter electron from lithium means that lithium has lost a minus charge and therefore must have a plus charge, this is called a cation. removing the electron also means now that there are no electrons in the s2 level do lithium is left with a 2s1 orbital, this is a very stable configuration and lithium wont loose any more electrons so your lithium ion will be nucleus with 3 protons 4 neutrons and 2 electrons with a plus charge to represent the loss of an electron
How does a helium atom have neutrons in if it is made from hydrogen atoms fusing and hydrogen does not have neutrons?
The weak interaction is capable of converting protons into neutrons plus anti-electrons.
What does lead plus hydrochloric acid equal?
hydrogen and led chloride :)
Which has high ionisation energy lithium or lithium plus?
lithium plus. removing electron from something that is positive is much harder.
