What is the atomic number of MN?
Manganese is a metal element. Atomic number of it is 25.
Are hydrogen 1 and hydrogen 2 isotopes?
Yes, hydrogen-1 and hydrogen-2 are isotopes of hydrogen. They have the same number of protons but different numbers of neutrons, with hydrogen-1 (protium) having no neutrons and hydrogen-2 (deuterium) having one neutron.
What are the chemical formulas for water and hydrogen peroxide?
The chemical formula for water is H2O, meaning it has two hydrogen atoms and one oxygen atom. The chemical formula for hydrogen peroxide is H2O2, indicating it has two hydrogen atoms and two oxygen atoms.
Are ammonia and hydrogen peroxide the same?
No it is not the same, Ammonia is NH3, a compound of hydrogen and nitrogen. It is a base and is note for its strong smell. Hydrogen peroxide is H2O2, a compound of hydrogen and oxygen. It is very mildly acidic and is noted for its ability to decompose and release oxygen gas.
Does acid or base contains hydrogen?
Acids release H+ ions. Therefore, Acids contain Hydrogen. Note: Bases contain OH- ions.
What is the atom weight of hydrogen?
The atomic weight of hydrogen is 1,007 94 ± 0,000 07 atomic units of mass.
How do you draw a orbital diagram for hydrogen with the atomic mass of 3 and atomic number of 1?
Note that hydrogen by definition always has an atomic number of 1, so it is not necessary for you to specify that. And if the atomic mass is 3, that is the tritium isotope, with 2 neutrons. The added neutrons have no effect on the orbit of the single electron, so the orbital diagram is exactly the same as if it were the more common hydrogen 1 isotope. One electron orbits the nucleus.
What is hydrogen 1?
Hydrogen exists as 3 isotopes: Hydrogen with 1 proton and 1 electron; Dueterium (also called Heavy Hydrogen) with 1 neutron, 1 proton and 1 electron, and Tritium having two neutrons, 1 proton and 1 electron. Note that all have 1 proton (i.e. the Atomic Number) being all the same element.
What is the atomic number of thulim?
The atomic number of thulium [note correct spelling] is 69.
What is the atomic number of chronium?
The atomic number of chromium [note correct spelling!] is 24.
What is the atomic mass number of element d?
The atomic mass number of an element is the total number of protons and neutrons in its nucleus. It is denoted by the symbol A. If you provide the symbol or name of element d, I can tell you its atomic mass number.
Base weight a system of comparing atomic weights to carbon is it true or false?
True. The unit for the atomic weights of chemical elements is the relative atomic mass unit (1/12 from the atomic mass of the isotope 12C). Note that atomic weights is used for elements and atomic mass for isotopes.
What could account for the fact that a lead atom has a much larger mass then a hydrogen atoms?
While not a perfect relation, the density of the materials increase with the atomic number or atomic mass. Hydrogen has a single proton, no neutrons (typically, although it can have up to 2 neutrons). It has an atomic number of 1 and an atomic mass of 1. Lead has 82 protons, and typically has 125 neutrons. It's atomic number is 82 and atomic mass of 207. The relative size of the atom doesn't increase linearly with the mass, and thus the density generally increases with the mass. Note that hydrogen is a gas at room temperature, but even in its liquid phase, it is one of the least dense materials (not counting porous materials like aerogels). The density of liquid Hydrogen is 67kg/m3, or 0.067g/cm3. Lead is solid at room temperature and has a density of 11.34 g/cm3 The lowest density solid known (so far) is an "evacuated silica nanofoam" with a density of 1mg/cm3, or 0.001g/gm3, and actually is lighter than air, less dense than liquid hydrogen, but more dense than gaseous hydrogen (about 0.08 mg/cm3)
What is the atomic number of sodiumhydroxide?
Sodium hydroxide {note presence of a space between words} is a compound and does not have any atomic number; atomic numbers are characteristics of atoms only.
What is isotopes hydrogen 1?
there are many isotopes of hydrogen. they are:-hydrogen -1 protium. hydrogeen - 2 deuterium.hydrogen - 3 tritium. hydrogen - 4 hydrogen - 5 hydrogen - 6 hydrogen - 7
What trend do you note for the atomic radii of period 3?
The size of atom decreasing.
What are the equations that albert discovered?
e=mc^2 which stated that when an atom is broken apart proton by proton, the strong nuclear force is eliminated, thus exerting immense amounts of force, ie the atomic bomb. Note: the hydrogen bomb is completely different.
