What is the symbol for a sodium isotope with 12 neutrons?
The symbol for a sodium isotope with 12 neutrons would be "Na-23". This notation indicates the element symbol "Na" for sodium and the total number of protons and neutrons in the nucleus (12 neutrons + 11 protons = atomic mass number 23).
What is the symbol and atomic number for the element sodium?
The symbol of sodium is Na and its atomic number is 11.
The correct symbol for the isotope of potassium with 22 neutrons is k 41 19?
The correct symbol for the isotope of potassium with 22 neutrons is K-41. The number after the element symbol represents the atomic mass, which is the sum of protons and neutrons in the nucleus. In this case, potassium has 19 protons and 22 neutrons, resulting in an atomic mass of 41.
What is the number above the elements symbol?
The number above an element's symbol in the periodic table represents its atomic number, which indicates the number of protons in the nucleus of an atom of that element. Atomic number determines the element's unique identity and its placement in the periodic table.
The mass number is .?
The mass number of an atom is the sum of the number of protons and neutrons in its nucleus. It is represented by the symbol "A" in the notation of X^A_Z, where X is the element symbol, A is the mass number, and Z is the atomic number.
How do you figure neutrons on periodic chart?
by subtracting the atomic number from the mass number. the atomic number is the one under the element's symbol and the mass number is the one above the element's symbol.
What does atomic mass number elements symbol elements name and atomic mass tell you about the element?
The element symbol represents one mole of element , atomic number represents number of protons, atomic mass represents sum of protons and neutrons.
What is nuclear symbol?
A nuclear symbol, also known as an atomic symbol, is a standard way to represent an element with a specific number of protons and neutrons. It consists of the element's chemical symbol, its atomic number (number of protons), and its mass number (sum of protons and neutrons). For example, the nuclear symbol for carbon-12 is ^12_6C.
Which element has 30 neutrons and 15 electrons?
There are a variety of isotopes that have 30 neutrons. It isn't the number of neutrons that determines an element, but the number of protons. Electrons generally balance the number of protons.
What is the atomic number of the element with the symbol Be?
The atomic number of the element with the symbol Be (Beryllium) is 4.
What does the symbol inside an elements square mean?
The symbol of an element is an abbreviation for the element's name, and it is derived either from the English or the Latin name. For example: Bromine's symbol is Br. The symbol inside an element's square is the element's atomic number, or the number of protons and neutrons in the element.
What three things can the periodic table tell you about an element?
NameAbbreviationAtomic Number (number of protons = number of electrons)Number of neutrons in various isotopesAtomic massValenceGroup
What is the sum of protons and neutrons known as an element?
Sum of protons and neutrons is the Mass number of the element. The number of protons is equal to the number of electrons. Neutrons and protons are sub atomic particles.
What is the symbol for 12p 10e 12n?
The symbol for an element is typically written as [A-Z][a-z][number], where A is the element's atomic number, Z is the element's chemical symbol, and the number represents the sum of protons and neutrons (called mass number). So, for 12 protons, 10 electrons, and 12 neutrons, the symbol would be Mg.
What is the atomic mass number of element d?
The atomic mass number of an element is the total number of protons and neutrons in its nucleus. It is denoted by the symbol A. If you provide the symbol or name of element d, I can tell you its atomic mass number.
What is a nuclide symbol?
A nuclide symbol represents a specific isotope of an element and consists of the element's chemical symbol, atomic number, and mass number. The chemical symbol is a one- or two-letter abbreviation for an element, the atomic number is the number of protons in the nucleus, and the mass number is the sum of protons and neutrons in the nucleus.
What is the atomic mass and symbol of an element with 34protons 33 neutrons 34 electrons?
The 34 protons means that this is the element that has an atomic number of 34, which is selenium. The mass number for the isotope given is 67, which is the sum of the protons and neutrons. Mass number is not the same as atomic mass. Atomic mass is the total mass of the protons, neutrons, and electrons in an atom.
