1 Atoms contain three different types of particle.These are electrons, neutrons and protons.(a) Which one of the three particles has a negative charge?(1)electron(s)(b) Which one of the three particles has the smallest mass?(1)electron(s)(c) Use words from the box to complete the ...
Atomic Number and Mass Number:The atom is the smallest representative unit of a single chemical element and it contains some numbers of protons, neutrons and electrons. The number of protons for an element is fixed and represented by its atomic number. The number of neutrons can vary, ...
The protons and neutrons cluster together to form the nucleus, the central part of the atom, and the electrons orbit about the nucleus. Protons and electrons both carry an electrical charge(电荷). The charges they carry are opposite to each other; protons carry a positive electrical charge whi...

Atomic Particles Atoms are made of protons, neutrons and electrons 99.999999999999% of the atom is empty space Electrons have locations desc
Understand that isotopes of an element have different mass numbers but the same number of protons. Using the Periodic Table, find the atomic number of the element. The atomic number equals the number of protons. In a balanced atom, the number of electrons equals the number of protons. In an...
An atom of gold is bigger and heavier. Split it open and you'll find 79 protons and 118 neutrons in the nucleus and 79 electrons spinning round the edge. The protons, neutrons, and electrons in the atoms of iron and gold are identical—there are just different numbers of them. In ...
Cloud of electrons An atomic nucleus is surrounded by a cloud of electrons. Electrons carry a negative charge that is equal and opposite to the charge carried by a proton. To form a neutral atom, the number of electrons has to equal the number of protons in the nucleus. ...
In a sense, protons and electrons are touching in an atom because electrons have properties of both particles and waves. The wavelength of an electron is comparable in size to an atom, so electrons can't get closer than they already are. ...
