The nucleus - protons and neutrons. This applies to all atoms.
What is the mass of potassium?Answer belowThe answer to your question is 39.0392. Try looking this stuff on google so your don't have to wait for an answer, or you don't get a stupid answer. I once looked up what the mass of an element is and they said "The mass is alot if you got the hand full. On the other hand ..." That and you will get a more detailed answer.If you were to lazy to read that, the answer is 39.0392.
negatively charged and takes up most of the atoms space Takes up most of the atoms mass and is negatively charged
Alkali MetalsLithium, potassium and sodium are considered to be some of the most active metals.
Most of the mass of an element is located in the nucleus, which contains protons and neutrons. Electrons, which have a much smaller mass, are located in the electron cloud surrounding the nucleus.
The sum of all Protons and Neutrons.
These particle are neutrons and protons; they are located in the atomic nucleus.
Potassium phosphate (K3PO4) has more atoms than calcium hydroxide (Ca(OH)2). This is because the formula for potassium phosphate contains 4 atoms (3 potassium atoms and 1 phosphorus atom), while the formula for calcium hydroxide contains 3 atoms (1 calcium atom and 2 hydrogen atoms).

39
A compound containing potassium and oxygen atoms would have a formula of K2O, and would be named potassium oxide. This is a binary ionic compound.
K-39 is the most abundant, constituting about 93 % of the atoms in naturally occurring potassium.
More then 99% of an atoms mass is in the nucleus.
the nucleus
Inside the nucleus.
no
mass of protons + mass of neutrons
The mass of an atom is concentrated in the nucleus (protons+neutrons).
