What else can I help you with?
Protons are so much more massive than electrons that you can neglect the mass of electrons when determining the mass of an atom?
Atomic mass is based on the proton and neutron. For the most part the mass of an electron is infinitesimally small.
The small central part of an atom?
The "dense" central portion of an atom is called the nucleus. The nucleus of an atom contains neutrons and protons.
The layer that contains 90 percent of the total mass of the atmosphere?
There are a few layers to the atmosphere however the Troposphere is the largest part of the atmosphere containing 75% of its mass. However the Troposphere contains 99% of the water vapour on the planet as well as Earth's aerosols. It is also where all weather phenomenon will occur.
Do the electrons of an atom contribute to mass of an atom?
Protons have a positive charge and weigh 1 AMU Neutrons have a neutral charge and weigh 1 AMU Electrons have a negative charge and 1184 electrons weigh 1AMU so they are thought to add nothing to the mass of an atom. You may want to check out Bohr's model or the duet/octet rule.
The part of the atom that accounts for electricity is the?
The electron is the part of the atom that accounts for electricity.
What part of the atom contains the majority of mass an atom has?
The nucleus contains the mass.
What part of the atom is the heaviest has the most mass?
The nucleus of an atom is the heaviest part and contains most of the atom's mass. It is made up of protons and neutrons. Electrons, which orbit the nucleus, have much less mass compared to protons and neutrons.
What part of the atom contains the least atomic mass?
Electron. Contains basicaly no mass what so ever.
What is a positively central part of an atom?
In the nucleus of an atom, the positively charged particles are called Protons.
Made up of the protons and neutrons this part of the atom contains nearly all the mass of the atom?
The nucleus is the part of the atom made up of protons and neutrons, and it contains nearly all of the atom's mass. Electrons, which have much lesser mass, orbit around the nucleus.
Which best describes the nucleus of an atom?
The nucleus of an atom is the densest part of an atom. It contains the protons and neutrons of an atom.
Which part of the atom contains all the mass?
Most of an atom's mass is concentrated in the nucleus, which is made up of protons and neutrons. While electrons contribute to the atom's overall structure, their mass is negligible compared to that of the nucleus. Thus, the nucleus is responsible for nearly all of the atom's mass.
Which part of the atom does the atomic mass measure?
The Nucleus contains Protons and Neutrons which comprise practically all the atom's mass.
Which of these is the part of an atom that contains the protons and neutrons?
The Nucleus. Which is inside the electron clouds.
Which best describes the nucleus of an atom A. It is the most massive part of the atom. B. It is the negatively charged part of the atom. C. It is made of neutrons and electrons. D. It contains no mas?
A. It is the most massive part of the atom. The nucleus, composed of protons and neutrons, contains the majority of an atom's mass, while electrons, which are negatively charged, orbit around the nucleus. Thus, options B, C, and D are incorrect.
Where are the Nuetrons and Protons located in the Atom K?
Neutrons and protons are located in the nucleus of an atom. The nucleus is the central part of an atom that contains most of its mass and is surrounded by electrons in the electron cloud.
What is an assembly of protons and neutrons within an atom called?
An assembly of protons and neutrons within an atom is called a nucleus. It is the central part of an atom that contains most of the mass of the atom and is positively charged due to the protons it contains.
