What is the atomic mass of an atom with 5 electrons?
you can't tell the atomic mass of an atom if either the number of protons or neutrons is missing. But Boron with 5 protons and 6 neutrons has and atomic mass of 11.
Why we sum protons and neutrons for the atomic mass why we don't take neutrons?
Protons and neutrons together make up virtually all of the mass of an atom, so we count them to figure out the mass. Counting protons alone will tell us what element and isotope the atom is, but counting neutrons alone tells us nothing.
What does the atomic mass tell you about the element and it's protons and neutrons?
The atomic mass of an element represents the average mass of its isotopes, taking into account their abundance. It is the sum of the protons and neutrons in the nucleus of an atom. By subtracting the atomic number (number of protons) from the atomic mass, you can determine the number of neutrons in the nucleus.
What does the atomic number of silicon tell you about number of protons neutrons and electrons?
The atomic number of silicon is 14. This means that a silicon atom has 14 protons in its nucleus, and a neutral silicon atom has 14 electrons. The number of neutrons depends on the particular isotope.
Which chemical element has 177 neutrons 77 protons and 77 electrons?
Atoms are defined by the number of protons in the nucleus; therefore, we can tell what element it is by the number of protons (the information about the neutrons and electrons is unnecessary). An atom with 77 protons is iridium.
How can you find out the number of neutrons in an atoms nucleus?
By the process of elimination. For example, The atomic weight of an atom is just the number of its protons, and the atomic mass is the total weight of protons and neutrons in the atom. So, the atomic weight of Oxygen is 8(protons) and the atomic mass is 16(protons + neutrons) so we can tell that there are 8 protons and 8 neutrons.
How can you tell if an atom is an ion?
If the number of protons and neutrons are the same, its an atom, if not its an ion
How is the number of neutrons in an atom worked out?
they work because in every atom there is a neutron, electron and proton. the electron will tell you what the atomic number is and the neutrons and protons will tell you what element it is.
What does it tell you about the nucleus of the carbon atom?
nucleus of carbon atom contains 6 protons and 6 neutrons.
The sum of the protons and the neutrons will tell the atomic what?
Atomic mass number of the atom. The best way to remember it is: the majority of the mass of an atom is made up of the protons and neutrons (the electrons are very light!), therefore the atomic mass number is the sum of the protons and neutrons.
What element that is a gas has eight protons and eight neutrons?
Oxygen. The Elements Atomic Number tells you the number of protons and it's amu is generally the weight of all of the averaged isotopes so since it is nearly 16 (not all O's have 8 neutrons) it is Oxygen.
What is the atomic mass of an atom with 5 electrons?
you can't tell the atomic mass of an atom if either the number of protons or neutrons is missing. But Boron with 5 protons and 6 neutrons has and atomic mass of 11.
What does the mass number of an atom tell you about the atom?
The mass number tells us the number (the sum) of protons and neutrons in the nucleus of an atom.
Why we sum protons and neutrons for the atomic mass why we don't take neutrons?
Protons and neutrons together make up virtually all of the mass of an atom, so we count them to figure out the mass. Counting protons alone will tell us what element and isotope the atom is, but counting neutrons alone tells us nothing.
What is a neutral stable atom with a mass of 8?
A neutral stable atom with a mass of 8 is most likely oxygen-16, which has 8 protons and 8 neutrons in its nucleus. This isotope of oxygen is the most common form of oxygen found in nature. Its stability is due to the balance between the attractive nuclear force and the repulsive electromagnetic force within the atom.
What atom has 23 protons and 29 nuetrons?
If it has 23 protons it has to be Vanadium no matter the number of neutrons. Deciding what element an atom is depends solely on the number of protons. However, the neutrons tell you which isotope of vanadium it is.
What does the atomic number of an element tell you about its atom?
It would tell you how many neutrons make up the Nucleus of the atom.
