Are the number of protons and electrons in an atom equal ? View Solution In which of the following elements the ratio of number of protons to the number of neutrons present in the atom is1:1 View Solution Exams
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...
Write the symbol of oxygen. Try to do this without referring to a table of elements.问的是元素符号还是符号?我写O就OK了吗?How many protons (and electrons) are in an atom of lithium? 答案是3吗?

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...
The northern lights occur when electrically charged particles from the sun — mostly electrons andprotons— slam into Earth's upper atmosphere at speeds of up to 45 million mph (72 million kph), but our planet's magnetic field protects us from the onslaught. ...
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. ...
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 ...
