How many protons are in the nucleus of a potassium atom?
19
How many electrons orbit the nucleus of the potassium atom?
19
What particle in a atom lives in the nucleus and has a charge of 1 plus?

What is the center of an atom called?
The center of an atom is called a nucleus (nucleifor plural).Center of an atom is called the "Nucleus".
The nucleus of an atom k-42 contains?
19 Protons and 23 Neutrons
How would you describe the nucleus of the atom?
the nucleus is the control center of the entire atom the nucleus of an atom has 3 basic subatomic particles: -the electrons which orbit the outside of the nucleus, electrons have a negative charge -the protons which are inside the nucleus and have a positive charge -neutrons which are also inside the nucleus have a neutral charge because they are neither positive nor are they negative something you need to know about protons and neutrons: the mass of the atom equals the protons plus neutrons and the atomic number of an atom tells how many protons are in an atom really being in the nucleus. The nucleus of an atom can best be described as the part of the atom with the biggest mass. It contains an atom's protons and neutrons.
What is the dense center of the atom called?
the denser part of an atom is the nucleus. about 99% of the mass of an atom is concentrated within the atom.
Difference between Na and Na plus?
Na+ will be a sodium atom that has lost an electron. Normally in atoms the amount of protons and electrons are equal, when you see a plus or minus charge on an atom its due to the loss or gain of electrons.
How many protons are in the nucleus of an atom of fluorine 19?
there are 19 protons in a fluorine-19 atom. Ironic huh? There are 9 protons in the fluorine 19 nucleus. There are 10 neutrons. The atomic number of fluorine is 9, which is the number of protons in a nucleus. The isotope number is the total number of protons and neutrons. The number of neutrons is different between fluorine 18 and 19 (9 and 10 respectively). They both have 9 protons.
