What is an atom's mass number?
The sum of the protons and neutrons in the nucleus
What is the mass number of silicon with 14 neutrons?
Mass number is the sum of protons and neutrons in the nucleus of an atom. The atomic number of silicon is 14, so the number of protons in the nucleus of a silicon atom is 14. If the isotope of silicon has 14 neutrons, then the sum of protons and neutrons is 28.
If an atom has 34 protons and 40 neutrons what is its atomic number?
The mass number is the sum of the number of protons and neutrons in the nucleus of the atom which is 74. Alternative answer 58 is the answer (???)
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
What is the mass number and what does it indicates?
The mass number of an atom is the sum of the numbers of protons and neutrons in the nucleus of the atom. It also indicates the total positive charge on the nucleus.
The sum of the numberof protons and nuetrons in the nucleus of an atom?
The sum of the number of the protons and neutrons in the nucleus of an atom is called as atomic mass.
Sum of protons and neutrons in the nucleus of an atom?
mass number
What is an atom's mass number?
The sum of the protons and neutrons in the nucleus
Mass number - atomic number?
This is the sum of all protons and neutrons in an atom. On the periodic table, it has the average for that element.
How is the mass number of a atom indicated?
The mass number is the sum of protons and neutrons in the nucleus of an atom.
What is the mass number of silicon with 14 neutrons?
Mass number is the sum of protons and neutrons in the nucleus of an atom. The atomic number of silicon is 14, so the number of protons in the nucleus of a silicon atom is 14. If the isotope of silicon has 14 neutrons, then the sum of protons and neutrons is 28.
How can an atoms mass number be determined?
it is the sum of the protons and neutrons present in the nucleus of the atom.
If an atom has 34 protons and 40 neutrons what is its atomic number?
The mass number is the sum of the number of protons and neutrons in the nucleus of the atom which is 74. Alternative answer 58 is the answer (???)
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
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.
Does mass number of an atom actually represents the mass of an atom?
The mass number is sum of neutrons and protons in the atomic nucleus.
What is the sum of protons neutrons in an atom?
Mass number = Protons+Neutrons
