What elements have the atomic number 12 and atomic mass 8?
There is no element with an atomic number of 12 and an atomic mass of 8. Atomic number corresponds to the number of protons in an atom, while atomic mass is the sum of protons and neutrons. The atomic number of an element cannot be smaller than its atomic mass.
What is the atomic mass of an element with 4 protons 5 neutrons and 4 electrons?
The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus. In this case, the element has 4 protons and 5 neutrons, so its atomic mass is 4 + 5 = 9 atomic mass units (amu). The number of electrons does not affect the atomic mass.
How many atoms of beryllium are present in a room with the dimensions of 8 feet by 13 feet by 15.1 feet if a sample of air contains 12.8 micrograms per meter cubed?
To calculate the total number of beryllium atoms present, we first need to determine the total volume of the room in cubic meters. Then, we can use the concentration of beryllium in the air to calculate the total mass of beryllium in the room. Finally, we can use the atomic mass of beryllium to convert the mass to the number of atoms.
If atomic mass of 16 and atomic number of 8 this means the number of neutrons in this type of oxygen is?
The number of neutrons in an atom can be calculated by subtracting the atomic number from the atomic mass. In this case, an atomic mass of 16 and atomic number of 8 for oxygen means there are 8 neutrons (16 - 8 = 8).
What is the atomic mass of boron?
The atomic mass of boron is approximately 10.81 atomic mass units.

The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus. In this case, the element has 4 protons and 5 neutrons, so its atomic mass is 4 + 5 = 9 atomic mass units (amu). The number of electrons does not affect the atomic mass.
What are the four element that have atomic number less than 8?
There are seven elements with atomic number less than 8: hydrogen, helium, lithium, beryllium, boron, carbon, and nitrogen. I don't know where you got the notion that there were only four. I thought you might be thinking of atomic mass instead, but that doesn't work either ... there are only 3 elements that have stable isotopes with a mass below 8 amu (hydrogen, helium, and lithium). 7Be exists, but it's radioactive.

The number of neutrons in an atom can be calculated by subtracting the atomic number from the atomic mass. In this case, an atomic mass of 16 and atomic number of 8 for oxygen means there are 8 neutrons (16 - 8 = 8).
How many neutrons are in a neutral beryllium atom?
A neutral beryllium atom has four neutrons. This is because beryllium's atomic number is 4, which means it has 4 protons in its nucleus, and since it is neutral it also has 4 electrons to balance the charge.
Gas atomic mass 16 8 nuetrons?
The number of protons and neutrons in an atom is equal to its atomic mass. Since the atomic mass of this gas atom is 16 and it has 8 neutrons, the remaining mass (16-8=8) must be the protons in the nucleus. Therefore, this gas atom has 8 protons.
What element has an atomic mass of 8 and 8 neutrons?
Oxygen has an atomic mass of 8 and typically has 8 neutrons.
What element has atomic mass of 16 and 8 neutrons?
If you had looked in the periodic table, you would have seen that the element Oxygen has an atomic mass of 16 (or more precisely 15.9994) and if you were to take that atomic mass and subtract the atomic number from it (i.e. 8) you would get a difference of 8 which is the number of neutrons it contains. In short, oxygen is that element.
What is the atom with atomic number 8 and mass number sixteen?
Atomic number 8 and mass number sixteen is Oxygen
What is the atomic number and atomic mass for oxygen?
Oxygen is a non meta element. Atomic mass of it is 16 Atomic number of it is 8.
