What is mass number of an atom?
The mass number of an atom is the total number of protons and neutrons in its nucleus. It is used to identify different isotopes of an element. The mass number is typically denoted as a superscript before the chemical symbol of the element (e.g. carbon-12 has a mass number of 12).
What is the mass number of an atom of sulfur with 16 protons 17 neutrons and 16 electrons?
Number of nucleons = number of protons + neutrons = 16 + 17 = 33 The mass number is thus 33 and the atom is denoted sulfur-33 or 33S.
What elements are denoted by Rn 7s25f11?
The element denoted by Rn 7s25f11 is Lawrencium (Lr), which has an atomic number of 103. It belongs to the actinide series of the periodic table. Lawrencium is a synthetic element and is highly radioactive.
What element is denoted as 1s22s22p63s23p4?
Total up the number of electrons. It appears to be 19, therefore, it likely corresponds to the 19th element on the periodic table, potassium.
What is the mass number of 15.9994?
The mass number of an element is the sum of the number of protons and neutrons in the nucleus of an atom. For an atom with a mass number of 15.9994, it indicates the average atomic mass of an oxygen atom.
What letters are used to designate atomic number and mass number in isotopic notation of atoms?
The atomic number is denoted by the letter "Z" and the mass number is denoted by the letter "A" in isotopic notation of atoms.
Atomic mass and mass number?
Atomic mass is the number of protons present in the nucleus or number of electrons revolving around the nucleus in an atom .It is denoted by Z. Mass number is the sum of number of protons and neutrons present in a nucleus in an atom .It is denoted by A.
Why complex no is denoted by z?
There are no real reason why it is denoted by z, but that the real number axis is denoted by x, imaginary number is denoted by y, the real part of a complex number is denoted by a, the imaginary part of a complex number is denoted by b, so there is z left.
Why is irrational number denoted with t?
It is not denoted with a t.
What is an atomic mass number?
Atomic mass and atomic number are two different things. Atomic mass is the mass of an atom compared to that of hydrogen. The atomic number is the atom's position in the periodic table. It's also the number of protons it has.
What is mass number of an atom?
The mass number of an atom is the total number of protons and neutrons in its nucleus. It is used to identify different isotopes of an element. The mass number is typically denoted as a superscript before the chemical symbol of the element (e.g. carbon-12 has a mass number of 12).
What is the number of an electron?
An electron has a mass of 9.109 X 10-31 kg, approximately 1⁄1840 the mass of a proton. However, the term mass number doesn't apply to electrons, it applies to atomic nuclei. The mass number of a nuclear isotope is the total number of protons and neutrons, together known as nucleons, of the isotope, and is denoted by (A).
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 particle have mass of lamu?
The tau neutrino has mass and is denoted with the symbol μ.
What is the mass number of an atom of sulfur with 16 protons 17 neutrons and 16 electrons?
Number of nucleons = number of protons + neutrons = 16 + 17 = 33 The mass number is thus 33 and the atom is denoted sulfur-33 or 33S.
Integers are denoted by an?
Whole number
What is the mass number of an element made up of?
The mass number of an element is the total count of protons and neutrons in its atomic nucleus. It is denoted by the symbol "A" and provides an indication of the element's isotopes. For example, carbon-12 has a mass number of 12, consisting of 6 protons and 6 neutrons. The mass number helps distinguish between different isotopes of the same element, which have the same number of protons but different numbers of neutrons.
