Nitrogen is a non metal element. Atomic number of it is 7.
An isotope of lithium with an atomic mass of ten would have an atomic number of 3, meaning it has 3 protons. To find the number of neutrons, subtract the atomic number from the atomic mass: 10 (atomic mass) - 3 (atomic number) = 7 neutrons. Therefore, an isotope of lithium with an atomic mass of ten would have 7 neutrons.
No, it is not possible for carbon to have 7 protons. Carbon is defined by having 6 protons in its nucleus, which gives it an atomic number of 6. If it had 7 protons, it would be classified as nitrogen, which has an atomic number of 7. Changes in the number of protons fundamentally alter the identity of the element.
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.
The atomic mass of the isotope 15N is 15,000 108 898 2(7).
Lithium has 3 protons thus even if it has 4 neutrons it is still atomic number of 3
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
The atomic number of an atom tells us its number of protons. Nitrogen's atomic number is 7. Thus, it has 7 protons.
Lithium by default contains 3 protons and 4 neutrons so its atomic mass is 6.941 amu (atomic mass units)
atomic mass - 14 atomic number - 7 It has that because it has 7 protons (and electrons) = the atomic number. And it also has about 7 neutrons and roughly, the mass number = the number of neutrons+ the number of protons.
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.
There are 4 neutrons in a lithium-7 atom. Lithium, which has atomic number 3, has 3 protons in its nucleus. If its atomic number is 3 (which is the number of protons in its nucleus) and its mass number is 7, we can find the number of neutrons by subtracting the atomic number from the mass number. In this case, 7 minus 3 equals 4.
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.
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.
Protons = atomic number EX: Nitrogen has 7 protons
Nitrogen's atomic number is 7. This is because nitrogen has 7 protons in its nucleus, which determines its atomic number. The atomic number defines the identity of an element and its position on the periodic table.
The number of protons an atom has is equal to its atomic number. In this case, there are 3 protons, so its atomic number is 3 and this is lithium (Li), the third element on the periodic table. Atomic mass is sum of the number of protons and neutrons in the nucleus. Here, that is 3 and 4, respectively, giving our atom an atomic mass of 7. The number of electrons does not affect either the atomic number or the atomic mass, but instead determines the bonding properties of the atom and whether it has a charge. If the number of electrons is equal to the number of protons, as is the case here, the charge is neutral (0). If there are more electrons than protons, the atom will be negatively charged (5 electrons and 3 protons --> charge = -2), and if there are more protons than electrons, the atom will be positively charged (2 electrons and 3 protons --> charge = +1).
