What is the internal structure of an atom – Answers.com

An atom has a nucleus containing protons (positively charged) and neutrons (without electrical charge); protons and neutrons contain quarks and gluons. Around the nucleus ar…e electron shells; electron is negatively charged. The mass of the proton or neutron is approx. 1 amu; the mass of electron …

Structure of an Atom | What is the Structure of an Atom

Structure of an atom is a key scientific theory. The most surprising feature is that an atom is mostly space. The mass is concentrated in the middle, in the nucleus, in which is positively charged. Orbiting round the nucleus but a long way from it are very light, negatively charged particles called electrons.

Atomic Structure | Atomic Physics | Science

Atomic Structure. An atom is a complex arrangement of negatively charged electrons arranged in defined shells about a positively charged nucleus. This nucleus contains most of the atom’s mass and is composed of protons and neutrons (except for common hydrogen which has only one proton). All atoms are roughly the same size.

Atom – Wikipedia

An atom is the smallest constituent unit of ordinary matter that has the properties of a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small; typical sizes are around 100 picometers (a ten-billionth of a meter, in the short scale ).
