What else can I help you with?
What does the nuclei of heavy atoms have that light atoms do not have?
Heavy atoms have more protons and neutrons in their nuclei compared to light atoms. This increases the nuclear charge and mass of heavy atoms, making them less stable and more prone to undergo radioactive decay.
Where is most of potassium atoms mass located?
Most of the mass of a potassium atom is located in its nucleus, which contains protons and neutrons. The electrons in the electron cloud surrounding the nucleus have significantly less mass compared to the nucleus.
What do Atoms of the same element have same atomic?
All atoms of the same element have the same number of protons, which is its atomic number. A neutral atom will have the same number of electrons as protons.
Which atoms are least likely to be radioactive?
Atoms with stable nuclei are least likely to be radioactive. Typically, atoms with an even number of protons and neutrons are more stable and less likely to undergo radioactive decay. This includes elements such as carbon-12, oxygen-16, and nitrogen-14.
Is the atom the smallest possible object?
at the moment, the smallest thing in the universe known to man is the neutrino, with a mass of less than 0. this is the opposite of an electron. electrons are one of the three main things that make up atoms.
What composes atoms?
Atoms are made of 3 types of subatomic particles, the protons and neutrons (which are in the center, or nucleus) and the electrons (which surround the nucleus). It should be noted that protons and neutrons are made of even more fundamental particles, called quarks.
What subtomic particle account for most all of an atoms mass?
Protons and neutrons, which are found in an atom's nucleus, account for most of an atom's mass. Electrons, which orbit the nucleus, have much less mass compared to protons and neutrons.
Have about 1800 times less mass than protons and neutrons?
Electrons have ~1800 times less mass than protons and neutrons
What is sodium number of protons electrons and neutrons?
Because atoms can be isotopes or ions, protons are the only stable identifier for an element (Sodium can have more or less than normal number of electrons or neutrons and still be sodium). Sodium has 11 protons.
Which particles account for most of an atoms mass?
Protons and neutrons are the particles that account for most of an atom's mass. Electrons, which have much less mass, play a negligible role in the overall mass of an atom.
Which contains a little mass out of the atoms three components?
Protons and Neutrons have almost equal mass. However, electrons mass is very less as compared to them.
Which particles account for almost all the mass of an atom?
Protons and neutrons account for almost all the mass of an atom. Electrons have much less mass compared to protons and neutrons.
