What is the atomic mass of an atom that has 6 protons 6 electron and 7 neutrons Please enter a numeric answer?
Carbon atoms with 7 neutrons have an atomic mass of 13 (6 protons + 7 neutrons = 13).
What would be the atomic mass of an atom with 6 protons 6 electrons and 8 neutrons?
Carbon-14: with 6 protons and 8 neutrons, and an atomic mass of 14.
Is mass a number?
Mass number is an integer (whole number) equal to the sum of the number of protons and neutrons of an atomic nucleus. In other words, it is the sum of the number of nucleons in an atom. Mass number is often denoted using a capital letter A. Contrast this with the atomic number, which is simply the number of protons.
What is the mass number of terbium?
158.92535 uTerbium / Atomic mass
What is the mass number of an atom that contains 19 protons 18 electrons and 20 neutrons?
Potassium-39 – It has 19 protons and atomic mass is 39. Hence, number of neutrons is 39 – 19 which is 20.
What is the mass number of an element that has 18 protons 18 electrons and 20 neutrons?
Because the mass number of an atom is the sum of proton number and neutron number of the atom. So, 18 + 20 = 38.
How do you find the mass number of neutrons and electrons?
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
What is the mass number of an ion with 106 electrons?
