Which two subatomic particles make up the atomic weight of an atom of an element?
The protons and the neutrons make up the atomic weight of an atom of an element, they have roughly the same mass and electrons have so little mass that they're negligible.
What makes up the weight an atom or molecule?
The number of protons and neutrons controls the weight of an atom.
What is the weight of the atom if an atom has 9 protons?
The weight (mass) of an atom with 9 protons will vary depending on the number of neutrons. 9 protons defines the atom as fluorine (F), and it can have 10 protons, making the mass 19 amu, or it can have a mass of 14 amu up to 31 amu, but the only stable isotope is the one with a weight (atomic mass) of 19 amu.
Which of these makes up an atom's mass number?
The mass number is the sum of the protons and neutrons in the atomic nucleus.
How do you find out what atom has what with only the electrons?
An atom (as from the Periodic Table, which have no charge) will have the same amount of protons as electrons. The atomic number is the amount of protons an atom has. Lithium has an atomic number of 3, which means it's nucleus contains 3 protons, and in turn 3 electrons. Once you identify the atom based on it's atomic number, and find it on the periodic table, you can see it's symbol, and weight. The atomic weight is the amount of protons and neutrons added together, both weighing 1 amu (*atomic mass units*: The unit that protons and neutrons are measured). Lithium has an atomic weight of 6.94, so the amount of protons (3) subtracted from 6.94 is 3.94. Now we round up to the nearest whole number and we have 4. Four is the amount of neutrons an atom of Lithium has.
What two parts of the atom make up the atomic weight of the atom?
The protons and the neutrons.
What is an atomic atom?
It's what everything in this world is made up of. It makes up matter.
Which two subatomic particles make up the atomic weight of an atom of an element?
The protons and the neutrons make up the atomic weight of an atom of an element, they have roughly the same mass and electrons have so little mass that they're negligible.
What sub atomic particles makes up mass of an atom?
Protons and neutrons
What makes up the weight an atom or molecule?
The number of protons and neutrons controls the weight of an atom.
Which sub atomic particle makes up most of the mass of atom?
These particles are proton and neutron.
Smallest unit of organization?
sub-atomic particle: which makes up an atom: which makes up molecules: which makes up DNA: which make up organelles (cell parts): which makes up cells: which makes up tissues: which makes up organs: which makes up organ systems: which makes up organisms.

In 4gm of Ag .calculate weight of one atom of Ag?
That should be mass, not weight. The mass of one atom of Ag doesn't depend on the size of the sample. Also, you can't "calculate" the mass of one atom from the information provided. You can look it up - or you can look up the atomic mass of Ag, and multiply it by the atomic mass unit.
Which of these makes up an atom's mass number?
The mass number is the sum of the protons and neutrons in the atomic nucleus.
How is atomic weight different than an atomic number?
atomic weight goes up faster
How can you predict an atoms approximate weight if you know its atomic number?
The atomic number is the number of protons or electrons in an atom (there are the same amount of protons and electrons in an atom unless it's positively or negatively charged). The atomic weight is the average weight of the protons or electrons plus the neutrons of all the different isotopes of the atom. That's one of the reasons why the atomic weight of each element on the table of elements is not an integer. If you multiply the atomic number by two, you'll have a fair estimate of the atomic weight for the top part of the periodic table. For the heavier elements, this will come up a little bit light.
