What is the atomic mass of gas?
The atomic mass of a gas depends on the specific element that the gas is composed of. For example, the atomic mass of oxygen gas (O2) is approximately 32 g/mol, while the atomic mass of hydrogen gas (H2) is approximately 2 g/mol.
Does the atomic mass of an element depend upon the relative abundance of each isotope of the element?
Yes, the atomic mass of an element takes into account the relative abundance of each isotope of that element. This is because atomic mass is the weighted average of the masses of all isotopes of an element based on their natural abundance.
What is meant the atomic number of an element?
The atomic number of an element is the number of protons found in the nucleus of an atom of that element. It uniquely defines an element and determines its chemical properties. Elements are arranged in order of increasing atomic number on the periodic table.
What does the atomic mass and number depend on?
As electrons have almost negligeable mass when compared to a proton, the mass of an atom mostly depends on the number of protons and neutrons in its nucleus. The mass of an electron is almost 1800 times smaller than the mass of a proton or neutron so in most calculations it can be safely assumed to be zero. In other words the mass of an atom depends on its atomic number.
Do nuclei have a positive or negative charge?
Atomic nuclei have positive electrical charges. The size of the charge depends upon the element in question.
What is the behavior of an element?
An Element's behavior depends PRIMARILY upon the Number of Protons in the Element's [atomic] Nucleus and secondarily upon the number of Neutrons that are included [with the occasional variation] in the Atomic Nucleus.

Yes, the atomic mass of an element takes into account the relative abundance of each isotope of that element. This is because atomic mass is the weighted average of the masses of all isotopes of an element based on their natural abundance.
What can you infer about two substances that have the same atomic number but different atomic mass what term would you use to classify the substance?
They are isotopes. They are the same element with a different amount of nuetrons, which can be determined depending upon the Atomic Mass and the atomic number, which results in the changed atomic mass.

The atomic number of an element is the number of protons found in the nucleus of an atom of that element. It uniquely defines an element and determines its chemical properties. Elements are arranged in order of increasing atomic number on the periodic table.
How do you find the atomic mass of an element?
Atomic mass (not to be confused with atomic mass number) refers to the mass of a given atom of a specific isotope, and is often expressed in unified atomic mass units. Atomic mass is found by adding together the individual masses of the protons and neutrons in the nucleus (the mass of electrons is comparatively insignificant). The value displayed on the periodic table is a weighted average based on the relative natural occurrence of all possible isotopes of an element.What makes atomic mass complicated is the fact that elements come in more than one isotope. Chemists need to know what a given element will actually weigh, in order to know how much to use (and so forth) when working with it in their laboratories, so the atomic mass refers to the actual weight of that element, per atom on the average. This depends upon the isotopes that exist, and also upon the relative abundance of those isotopes. It can only be determined experimentally, it is not something derived from the periodic table. You have to actually weigh the element to find out what it weighs.*The atomic mass number of an element is the total number of neutrons and protons for a given isotope. For example 14C or carbon-14 has 6 protons and 8 neutrons.

What is the mass of gas?
Atomic Mass is the count of how many protons and neutrons an element contains. So, there is not really an answer to your question. It would depend upon what elements the gas is made up of.
Do nuclei have a positive or negative charge?
Atomic nuclei have positive electrical charges. The size of the charge depends upon the element in question.
What happens to an atom in terms of atomic mass and weight when it loses one particle?
If an atom looses an electron, neither the atomic mass nor atomic weight change appreciatively. If it looses a proton or neutron, both atomic mass and atomic weight decrease by one and it becomes an atom of a different element (on loss of a proton), or a different isotope of the same element (upon loss of a neutron).
The number of positively charged protons in an atoms nucleus depends on?
The number of positively charged protons in an atom's nucleus depends on the atomic number of the element. Each element has a specific number of protons in its nucleus which determines its unique identity.
