Write the chemical symbol for the ion with 95 protons and 89 electrons?
the number of protons stay the same in every element (i think). So the number of protons is the atomic number. Therefore, this is tungsten (W). The electrons and nuetrons are the only thing that change.
How many protons neutrons and electrons in 58cr and 63cr?
Assuming that the questioner intended to write "Cr" instead of "cr", the isotopes indicated are those of the element chromium, whose atomic symbol is "Cr" and whose atomic number is 24. The atomic number is defined as the number of protons in a nucleus of each atom, and the atomic mass number, which precedes the atomic symbol, is defined as the number of protons and neutrons combined. In order to maintain electrical neutrality as is required for any atom, the number of electrons must be the same as the number of protons. From the definition of mass number, it follows that the number of neutrons is equal to the atomic mass number minus the atomic number. Therefore, each isotope named in the question has 24 protons and 24 electrons, but the isotope with mass number 58 has 32 neutrons and the isotope with mass number 63 has 32 neutrons has 39 neutrons.
How do you figure out how many protons and neutrons are in an atom?
you use the mass number for the neutrons. you take away the atomic nomber from the mass number and the answer is the number of neutrons. for the electrons and the protons you just write the atomic number.
How do you ionize a compound?
Add or take out an electron so that the atomic charge is unbalanced to get an ion.
What is Lewis's dot diagram for salt?
Draw the symbol for Sodium and Chlorine. This would create sodium chloride, which is table salt. The symbol for sodium is Na, so you write this down. Beside it, you write the symbol for Chlorine, which is Cl, then you place this in square brackets. After doing so, you may now place it's ionic charge outside the brackets in subscript. The result would be Na[Cl]-1.
Why do not use the atomic number often when you write the atomic symbol?
Because the atomic symbol implies a corresponding atomic number.
How can you write an atomic number?
If you mean how can you write an atomic number with the element's symbol, you write the atomic number as a subscript in front of the element's symbol.Examples4Be, 79Au, 109Mt
A radioactive isotope has eight neutrons Write the atomic number and mass number of this radioactive nitrogen as a chemical symbol with a subscript and superscript?
The atomic number of nitrogen is 7. When it is a radioactive isotope you add the number of neutrons to the atomic number (equaling 15). You then write 15 over 7 next to a capital 'N' representing Nitrogen.
How do you write atomic numbers in symbolic notation?
the mass goes on top and the the atomic number on the bottom ie: 12/6 C
What are two ways to write the isotope of bromide that has 10 more neutrons than its atomic number?
1- the name then the nuclear symbol.
Write out atomic number for lithuim?
Lithium is a metal element. Atomic number of it is 1.
Write the name and atomic number for He?
The element is Helium witht he atomic number, 2.
How do you find hyphen notation?
Hyphen Notation is the name of the element, then hyphen, then the mass number written after the element. For example, Chlorine-35.
A symbol used to write a number?
factor
What is the definition for atomic symbol?
Atomic symbols are the shortened version of the name of an element, often determined using its Latin name. For example, Calcium is abbreviated to "Ca" and is much easier to write out than Calcium is.
Write the chemical symbol for the ion with 95 protons and 89 electrons?
the number of protons stay the same in every element (i think). So the number of protons is the atomic number. Therefore, this is tungsten (W). The electrons and nuetrons are the only thing that change.
How do you write an isotope in shorthand?
Usually, the base element name followed by the mass number 'A', such as Carbon-12. You can also use the atomic symbol preceded by the mass number as a superscript. Some isotopes have special names and atomic symbols: Hydrogen-2: Deuterium (D) Hydrogen-3: Tritium (T) Helium-2: Diproton (Theoretical, not actually possible because of physics-y stuff)
