How do you find the mass number?
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
What has 7 protons and 7 neutrons?
Nitrogen Nitrogen is an atom that has 7 protons, 7 neutrons, and 7 electrons.
What is the mass number of an atom with 7 protons 7 neutrons and 7 electrons?
However, in the periodic table, the atomic mass for nitrogen is 14.01. This is possible as the nitrogen exists in different forms of isotope. When the number of protons is 7 and the number of neutrons is 7, then the isotope will be 14N, where the mass number is 14.
How do we find atomic mass?
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
How do you calculate an atom’s mass?
In an element atomic mass of an atom can be calculated by adding the mass of protons and neutrons.
What are the 3 ways to find the mass number?

What is the mass number of an atom with 7 protons 8 neutrons and 7 electrons?
15 amu The nitrogen is the chemical element which is denoted by the symbol N. The atomic number of nitrogen is 7. A nitrogen atom with 7 protons and 8 neutrons has a mass number of 15 amu,. However, in the periodic table, the atomic mass for nitrogen is 14.01.
Where is the mass number?
An element's mass number is unique to that element, and it's listed right underneath the element's symbol in the periodic table. The mass number of an element is not the same as its atomic number.
What is the mass of an atom?
The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope.
