The mass number is always the sum of the numbers of protons and neutrons and therefore is 39 in this instance. The atomic number of 19 shows that the atom is of the element potassium, and its symbol is 39K.
39, the sum of the numbers of protons and neutrons.
This isotope is potassium-39; potassium has the atomic number 19.
This atom is the isotope K-39 of potassium:
- Atomic Mass: 38,963 706 68(20)
- Atomic number: 19
- Mass number: 39
This is the isotope potassium-39 with the atomic mass 38,637 066 8(20).
The atomic of the atom would be 39
19
A neutral carbon atom contains 6 protons, 6 neutrons, and 6 electrons. The number of protons and electrons is equal, giving the atom a neutral charge.
The element with 74 protons is tungsten (symbol W). The number of electrons and neutrons does not affect the identity of the element, which is solely determined by the number of protons.
Argon has 18 protons, 22 neutrons, and 18 electrons.
An atom with 4 protons and 6 neutrons will have a total charge of +4 due to the protons. To be electrically neutral, it needs 4 electrons to balance the positive charge from the protons.
Protons- 30 Electrons- 30 Neutrons- 35 Zn-65 means the atomic number plus the number of neutrons equals 65. Zinc always has 30 protons; therefore, it's atomic number is 30 and it has 30 protons and electrons. The remaining number is the neutrons: 65-30= 35
There are similar number of neutrons and protons. It contains 29 neutrons and protons.
The nucleus of an atom contains only protons and neutrons; there are never any electrons in the nucleus. The number of neutrons is generally equal to or greater than the number of protons.
Protons, electrons, and neutrons are the three main parts of atoms. In an atom, the nucleus contains the protons and neutrons, the electrons are found in shells around the nucleus. On the periodic table, the atomic number tells you the number of protons of an element.
Number of protons = Number of electrons = Atomic number Number of neutrons = Atomic number - Number of protons
No. The number of neutrons has no affect on the number of protons and electrons.
An atom with 4 protons and 6 neutrons will have a total charge of +4 due to the protons. To be electrically neutral, it needs 4 electrons to balance the positive charge from the protons.
there are 7 neutrons, 7 protons, and....----electrons
Americium has 95 protons and electrons. Number of neutrons: atomic mass of an isotope - number of protons
It contains 104 electrons/protons and 159 neutrons.
The element with atomic number 35 is bromine (Br). It has 35 protons and since it is neutral, it also has 35 electrons. To find the number of neutrons, subtract the atomic number (35) from the atomic mass (80). So, bromine-80 has 45 neutrons.
Uranium isotopes have 92 protons and electrons; the number of neutrons is different for each isotope.Number of neutrons = Mass number - Number of protons
Protons: 10 Electrons:10 and Neutrons: 10.
