What does an atomic mass number look like?
Example: the atomic mass number of uranium is 238,02891 - exprimed in atomic mass units.
What is the atomic number and mass number of deuterium 2H?
As Deuterium and Tritium are both merely isotopes of Hydrogen and not elements in their own right, they both have an atomic number of 1, just like Hydrogen (Hydrogen-1). Deuterium (Hydrogen-2) has an atomic mass of 2, and Tritium (Hydrogen-3) has an atomic mass of 3.
What is atomic number for potassium?
The atomic number of potassium (K) is 19.The atomic weight of K is 30.0983 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!I believe the atomic weight is 39.0983.19
What are the properties of elements that vary periodically with the atomic number?
The properties like electronegativity , ionisation energy , enthalpy changes vary periodically with atomic number.
How are atomic number and atomic mass related to atomic structure?
The atomic number tells how many protons are in the atom, and the atomic mass tells how many neutrons and protons are in the atom together. Like Oxygen has an atomic number of 8. It also has 8 protons. It's atomic mass is 16. It also has 16 neutrons and protons. Helium's atomic number is 1. It only has 1 proton. It's atomic mass is 1 because it doesn't have any neutrons.
What does an atomic mass number look like?
Example: the atomic mass number of uranium is 238,02891 - exprimed in atomic mass units.
How many dots does a giraffe have?
The spots are unique to each giraffe, like a fingerprint, and vary in number and shape.
What is the atomic number and mass number of deuterium 2H?
As Deuterium and Tritium are both merely isotopes of Hydrogen and not elements in their own right, they both have an atomic number of 1, just like Hydrogen (Hydrogen-1). Deuterium (Hydrogen-2) has an atomic mass of 2, and Tritium (Hydrogen-3) has an atomic mass of 3.
How is atomic weight different than an atomic number?
atomic weight goes up faster

Where could a person go to buy a safe with a fingerprint scanner?
Safes with fingerprint scanner are the safest types of safes with a fingerprint lock interface. One can buy a safe with a fingerprint scanner from a websites like Amazon.
What are the properties of elements that vary periodically with the atomic number?
The properties like electronegativity , ionisation energy , enthalpy changes vary periodically with atomic number.

Is the atomic number is equal to the nuclear charge?
the atomic number does not equal the number of atoms. the number of atoms is stated in the equation like: H2+O=H2O2 hydrogen atoms 1 oxygen atom the number says all.The atomic number tells the number of protons.
What is the atomicic mass number equal to?
It looks like you have combined two concepts. The number of protons in an atom is the atomic number. The sum of the protons and the neutrons in an atom is the mass number. There is no such thing as an atomic mass number.
How many neutrons and protons are there in an atom?
The number of protons is equivalent to the atomic number which can be got from the periodic table. The number of neutrons is the atomic weight minus the number of protons. Again, this information is available from the periodic table.
What does a DNA fingerprint look like?
A DNA fingerprint could appear in a few different ways depending on it's use. Sometimes a DNA fingerprint just appears as a series of lines on a square board.
