Nitrogen has an atomic mass of 14 and an atomic number of 7 so the number of neutrons must be?
The atomic mass of an atom is the total mass of its particles. The atomic number is the number of protons in the atom's nucleus. To find the number of neutrons in an atom, we take its atomic mass (the total mass of its particles) and subtract its atomic number (the number of protons and electrons in the atom). A: Lithium has an atomic mass of 7 and an atomic number of 3 so the number of neutrons is equal to 4. (7 - 3 = 4)
How do you determine neutrons?
take nitrogen as an example it has an atomic number of 7 that determines the number of protons as 7 positive charges so it takes 7 negative charges (electrons) to even it out so you have 7 electrons and protons. then you take the atomic mass which is 14.01 but you can round it to 14. then you take the atomic number and atomic mass and subtract them (14-7=7) so the number of neutrons is 7.
How many neutrons in C-13 in isotope?
Carbon 13 has 7 neutrons.The atomic mass represents the total number of protons and electrons. Carbon atoms have 6 protons. Therefore, the atomic mass being 13, it has 7 neutrons.
What is the atomic mass of oxygen-15?
The atomic mass of oxygen-15 is 15. The atomic mass consists of protons and neutons, and oxygen-15 has 8 protons and 7 neutrons.
What is the lightest element metal?
Lithium is the lightest element metal with a relative atomic mass of 7 (3 protons, 4 neutrons).
What is the number of an atom with 3 protons 4 neutrons and 3 electrons?
The number of protons in the nucleus is given by the atomic number. So in your example, this would be atomic number 3 (lithium). It will have atomic mass of 7 (3 protons + 4 neutrons), and a charge of 0 since there are also 3 electrons to balance the 3 protons.
If an atom has 7 protons 7 neutrons and 7 electrons what would be the atomic number?
The answer is 7. The amount of protons is always the atomic number of the element. If the protons (atomic number) changes then the element changes
What is the protons for nitrogen?
The atomic number of an atom tells us its number of protons. Nitrogen's atomic number is 7. Thus, it has 7 protons.
What is the atomic number of Lithium-7?
Lithium has 3 protons thus even if it has 4 neutrons it is still atomic number of 3
What is the total number of neutrons in an atom of 7 lithium 3?
The atomic number of lithium is 3, which means that there are three protons. The number of neutrons depends on the mass number of the particular lithium isotope. Mass number is the SUM of the protons and neutrons. An atomic number of 3 and a mass number of 7 means that there are three protons and four neutrons. Lithium has two stable isotopes, Li-6 and Li-7 which means that there are 3 or 4 neutrons, respectively. The atomic number of lithium is 3, which means that there are three protons. The number of neutrons depends on the mass number of the particular lithium isotope. Mass number is the SUM of the protons and neutrons. An atomic number of 3 and a mass number of 7 means that there are three protons and four neutrons. Lithium has two stable isotopes, Li-6 and Li-7 which means that there are 3 or 4 neutrons, respectively.
How many protons are in nitrogen?
The number of protons in an atom will always be the same as the atomic number. Luckily, the periodic table is organized by increasing atomic number, so finding how many protons are in nitrogen just becomes an exercise of reading the periodic table. In this case, the atomic number of nitrogen is 7.See periodic table below.
What does an atom of lithium-7 have as an equal number?
In a neutral atom of lithium-7, the number of protons equals the number of electrons. The atomic number of lithium is 3, which is the number of protons. So a neutral atom of lithium-7 has 3 protons and 3 electrons.
What is nitrogens atomic number and why?
Nitrogen's atomic number is 7. This is because an element's atomic number is always the same as the number of protons in its nucleus. Since nitrogen has 7 protons, its atomic number is 7.
How do you figure out protons?
Protons = atomic number EX: Nitrogen has 7 protons
What is the number of protons electrons and neutrons in n-14?
Nitrogen-14: 7 Protons, 7 Electrons, 7 Neutrons To work this out in the future for other elements: Protons = Atomic Number Electrons = Atomic Number Neutrons = Atomic Mass - Atomic Number Hope this helps!
How many protons electron and neutrons are in nitrogen?
A neutral nitrogen atom has 7 protons, 7 neutrons, and 7 electrons. If it is electrically charged, the number of electrons will be different. If it is an isotope of nitrogen other than the most common (N-14), the number of neutrons will be different. Protons = Atomic Number Neutrons = Atomic Mass - Protons Electrons = Protons Atomic number is the amount of protons in element.
What am I have 4 neutrons and I am metallic what am I?
7Li or lithium-7.The mass number of an isotope is the sum of the protons and neutrons in its atomic nuclei. The atomic number of Li is 3, so lithium-7 would have 3 protons and four neutrons.
