How can you tell the number of protons and neutrons in its nucleus?
The number of protons in an atomic nucleus is indicated by the atomic number, which is unique to each element and can be found on the periodic table. To determine the number of neutrons, subtract the atomic number from the atomic mass (rounded to the nearest whole number). For example, if an element has an atomic number of 6 (carbon) and an atomic mass of approximately 12, it has 6 protons and 6 neutrons (12 - 6 = 6).
What is indicated by the atomic mass?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
What indicates the number of protons?
The number of protons in an atom is indicated by the atomic number of the element. It is the whole number located above the element's symbol in the periodic table. The atomic number also determines the element's identity.
How many protons neutrons electrons does Cs have?
Cesium (Cs) has 55 protons, as indicated by its atomic number. In a neutral atom, it also has 55 electrons. The number of neutrons can be determined by subtracting the atomic number from the atomic mass; the most common isotope of cesium has approximately 78 neutrons (55 protons + 78 neutrons = 133 atomic mass).
How many protons and neutrons are in atom of 160 Gd?
An atom of (^{160}\text{Gd}) (Gadolinium) has 64 protons, as indicated by its atomic number. To find the number of neutrons, subtract the atomic number from the mass number: (160 - 64 = 96) neutrons. Therefore, (^{160}\text{Gd}) contains 64 protons and 96 neutrons.
The number of protons an atom contains is indicated by its?
Atomic number.

How do you determine how many protons are in an element?
The number of protons in an element is determined by its atomic number, which is the whole number found on the periodic table for each element. Each element has a unique number of protons that gives it its specific identity.
How many protons and nertons are in Rg-272?
Rutherfordium-272 (Rg-272) has 104 protons, as indicated by its atomic number (104). The number of neutrons can be found by subtracting the atomic number from the mass number: 272 - 104 = 168 neutrons. Therefore, Rg-272 has 104 protons and 168 neutrons.
This element has an atomic number that is double the atomic number of silicon?
this elemnt has an atomic number that is double the atomic number of silicon?
The number of atoms of each element present in the molecule is indicated by what?
The number of atoms of each element present in a molecule is indicated by the subscript to the right of the element symbol in the chemical formula. For example, in H2O, there are 2 hydrogen atoms and 1 oxygen atom.
What is the number of protons in the neucleus called?
the answer is that it is called a atomic number.
How many atoms does the element phosphorus have?
The element phosphorus has 15 atoms, as indicated by its atomic number on the periodic table.
This element has the atomic number that is double the atomic number of silicon?
The element with an atomic number that is double the atomic number of silicon is germanium, with an atomic number of 32. Silicon has an atomic number of 14.
