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.

An atom which has 4 protons and 6 neutrons will be electrically neutral if it contains?
It will have 6 electrons since an atom is neutral when its number of protons is the same as its number of electrons.
Determine the numbers of electrons protons neutrons 80 35 Br?
Number of Protons: 35 Number of Neutrons:45 Number of Electrons:35
An atom contains 70 protons 70 electrons and 99 neutrons What is the mass number?
it is 169
What is tha neutron for calicum?
An atom contains protons, neutrons, and electrons. The electrons are tiny. They can be found in a fast-moving cloud, orbiting the nucleus. Each electron has a charge of -1. The nucleus contains the protons and neutrons, which are packed tightly together. The protons each have a charge of +1, and the neutrons have a charge of zero. The mass number of an element is the number of protons and the number of neutrons added together. Since the number of protons is equal to the atomic number of the element, the number of neutrons can be found by subtracting the atomic number from the mass number.
What is the protons neutrons and electrons for 65Zn?
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
How many protons neutrons and electrons are in a neutral atom of 64Cu atomic number 29?
There are similar number of neutrons and protons. It contains 29 neutrons and protons.
Does a nucleus have the same number of protons and electrons?
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 these?
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.
What are the number of protons neutrons and electrons in an element?
Number of protons = Number of electrons = Atomic number Number of neutrons = Atomic number - Number of protons
Do electrons equal the sum of the number of neutrons and protons in an isotope?
No. The number of neutrons has no affect on the number of protons and electrons.
An atom which has 4 protons and 6 neutrons will be electrically neutral if it contains?
It will have 6 electrons since an atom is neutral when its number of protons is the same as its number of electrons.
