| 6 | Carbon (C) | 4 |
| 7 | Nitrogen (N) | 5 |
Is nitrogen a neutral atom or ion?
Nitrogen-14 has no charge which means that no electrons are removed or added in the atom. Therefore it is neutral.
What’s the neutrons for nitrogen?
| Name | Nitrogen |
|---|---|
| Atomic Mass | 14.007 atomic mass units |
| Number of Protons | 7 |
| Number of Neutrons | 7 |
| Number of Electrons | 7 |
How many neutrons does boron have?
6 neutrons
The mass number for boron is 5; this The atomic mass of boron (symbol B) is 10.8. To determine the number of neutrons we round 10.8 to 11 and subtract the atomic number (5) and get 6; therefore, boron has 6 neutrons.
Does nitrogen always have 7 neutrons?
The atomic number is always 7. However, the atomic mass number, A, changes. However, not all nitrogen nuclei have 8 neutrons in a nucleus. They can have 5, 6, 7, 8, 9, 10 or 11 neutrons….

What has a mass number of 24 and 13 neutrons?
element sodium
If an atom has a mass number of 24 and also has 13 neutrons, the atomic number of the atom will be 11 and the atom will belong to the element sodium….
What has 12 protons and 23 neutrons?
Magnesium
#12 – Magnesium – Mg. It is the eighth most common element in the earth’s crust, but is the most commercially used element.
What element has atomic number of 6 and 7 neutrons?
For most elements other than hydrogen, isotopes are named for their mass number. For example, carbon atoms with the usual 6 neutrons have a mass number of 12 (6 protons + 6 neutrons = 12), so they are called carbon-12. Carbon atoms with 7 neutrons have atomic mass of 13 (6 protons + 7 neutrons = 13). These atoms are the isotope called carbon-13.
Which do elements have more neutrons than protons?
The stable isotopes of the heavier element have a great surplus of neutrons compared to the number of protons. For example the stable isotope of uranium, U_238, has 92 protons and 146 neutrons, nearly a (3/2) to 1 ratio. This may be a matter of that combination involves a lower energy than other combinations of the same number of nucleons.
What is element with 6 protons in its nucleus?
The element carbon (C) has an atomic number of 6, which means that all neutral carbon atoms contain 6 protons and 6 electrons. In a typical sample of carbon-containing material, 98.89% of the carbon atoms also contain 6 neutrons, so each has a mass number of 12.
What element has 6 electrons?
Carbon has 6 electrons — 2 in the first shell, and 4 in the second shell (so four valence electrons). Nitrogen has 7 electrons — 2 in the first shell, and 5 in the second shell (so five valence electrons).
