Is helium only one type of atom?
There are two naturally occurring isotopes of helium: He-3 (which is very rare, comprising 0.00014% of naturally occurring helium), and He-4 (which comprises the other 99.99986%of naturally occurring helium). Whether helium is one type of atom or not then depends on the definition of "one type of atom"; if He-3 and He-4 are considered different types of atom due to their differing numbers of neutrons, then no, helium is not one type of atom; if He-3 and He-4 are both considered the same type of atom due to their common number of protons, then yes, helium is one type of atom.
How many atoms are there in the formula of water?
The chemical formula of water is H2O; water contain two hydrogen atoms and one oxygen atom: 2 + 1= 3 atoms.
What has 7 atoms in each molecule?
A molecule of water (H2O) has 3 atoms: 2 hydrogen atoms and 1 oxygen atom.
A Lithium atom has an atomic mass of 6 How many neutrons does this atom have?
This atom has three neutrons. The atomic mass number is the sum of the protons and neutrons. All atoms of the same element have the same number of protons (lithium has three), so the neutrons have to account for the rest of the mass. 6 (the mass number)-3 (the number of protons in a lithium atom)=3. So this atom must have three neutrons.
What the atomic number tell us?
The atomic number of an atom is the number of protons in the nucleus of an atom. The number of protons determines the identity of an element and its properties. Hope this helps :3
What is the total number of atoms in this formula H2O?
i think it's 6 moles of Hydrogen and 3 moles of oxygen. give the complete reaction to understand better.
What is the oxidation number of 3 H2O?
The oxidation number of H in H2O is +1, and that of O is -2. Since there are three H2O molecules, the total oxidation number would be 3(+1) + 3(-2) = -3.
What is the number of each type of atom in NaHCO3?
Sodium bicarbonate has: 1 sodium atom, 1 hydrogen atom, 1 carbon atom, 3 oxygen atoms.
How many electrons do an atom with an atomic number of 3?
if it is a netrual atom it will have 3 but if it is charged it will change
What is the total number of atom in H2O?
The water molecule is made up of 2 atoms of Hydrogen and one atom of Oxygen. So a total of 3 atoms. For other measurements, google Avogadro, mols, etc.
What does an atom of lithium-7 have as an equal number?
In a neutral atom of lithium-7, the number of protons equals the number of electrons. The atomic number of lithium is 3, which is the number of protons. So a neutral atom of lithium-7 has 3 protons and 3 electrons.
What does 3 types of subscript tell you?
- the atomic number of a chemical element or- the number of a type of an atom in a molecule or- indices for physical/chemical parameters
How many atoms are in 2.25 mol of water?
The number of molecules is 15,055 352 142 5.10e23.
How many atoms are there in H2O?
There are 3 atoms in a water molecule (H2O) - 2 hydrogen atoms and 1 oxygen atom.
How you balance so2 plus h2s equals equals s plus h2o?
To balance the equation SO2 + H2S = S + H2O, we need to ensure that there are equal numbers of each type of atom on both sides of the equation. Begin by placing coefficients in front of the compounds to balance the number of sulfur and hydrogen atoms, then balance the oxygen atoms last by adjusting the coefficient for H2O. The balanced equation is SO2 + 2 H2S = 3 S + 2 H2O.
What number of protons in lithium?
Lithium has the atomic number of 3, which means it has 3 protons, and a neutral atom of lithium has 3 electrons.
How many atoms does H2O have?
Three, two hydrogen and one oxygen. The suffix after the H tells you that there two, no suffix after O tells you there is only one.
