Electrons spin around the nucleus, like the earth orbits the sun
Electrons. They have a negative charge.
They are not in the nucleaus, they orbit around the nucleus.
Electrons move fast around the nucleus at speeds close to the speed of light. The exact speed of an electron is determined by its energy level and its distance from the nucleus.
As you move from left to right across a period, the attraction an atomic nucleus has for the atom's electrons increases. This is because positively charged, relatively heavy protons are being added to the nuclei as you move from left to right, and the additional protons have an increased attraction for the negatively charged and nearly weightless electrons.
Electrons move around the atomic nucleus.
Electrons move around the nucleus of an atom. Protons and neutrons are located in the nucleus at the center of the atom. Electrons orbit the nucleus in specific energy levels, or shells.
Electrons move around the nucleus of an atom. Electrons have a negative charge.
The atomic radii decrease across a period because as you move from left to right, the number of protons and electrons in the atoms increases, leading to a stronger attraction between the nucleus and the outer electrons. This results in the electrons being pulled closer to the nucleus, making the atomic radius smaller.
Neutrons and protons are placed in the atomic nucleus; electrons move surrounding this nucleus in clouds of electrons.
Ionization energy increases as you move across the periodic table from left to right. This is because the number of protons in the nucleus increases, leading to a stronger attraction between the nucleus and the electrons, making it harder to remove an electron.
It is the electron cloud that surrounds the nucleus of an atom. The electrons move in their orbits around the nucleus, and they form the cloud.
