Because they are the outer electrons in an atom and they orbit around the nucleus. But you should ask a scientist this question. NOT put it on ask.com.
OR look it up on Google.com. it is very likely that you will find something there.
The moons stay in orbit around Jupiter due to the planet's strong gravitational pull. This gravitational force keeps the moons in check and prevents them from moving away into space. They orbit around Jupiter because of the balance between their inertia and the gravitational force pulling them towards the planet.
The moon is held in orbit around the Earth by gravity. The gravitational pull between the Earth and the moon keeps the moon moving in a consistent path around the Earth.
Planets are held in their orbits around the Sun by gravity. The gravitational pull from the Sun keeps the planets moving in their elliptical paths. This balance between the planet's velocity and the gravitational force from the Sun keeps them in a stable orbit.
Electrons orbit around the nucleus of an atom in specific energy levels or shells. These electrons are negatively charged particles that are attracted to the positively charged nucleus through electrostatic forces. The motion of the electrons around the nucleus is constrained by quantum mechanics and is best described as existing in a cloud of probability rather than a fixed path.
Electrons orbit the nucleus of an atom. They move in specific energy levels called electron shells. The nucleus contains protons and neutrons.
Two (2) electrons can be held in the first orbit.
2 electrons maximum. 1s2
The maximum number of electrons that can be held in the third orbit of an atom is 18. This is based on the formula 2n^2, where n is the principal quantum number of the orbit. For the third orbit (n=3), the maximum number of electrons is 2 x 3^2 = 18.
Between electrons and the atomic nucleus a repulsion exist.

The orbit or electron shell closest to the nucleus is the 1s sub-shell. It can hold 2 electrons before the 2s sub-shell is filled. H and He have their electrons in this shell (the 1s)
The second orbit can hold a maximum of 8 electrons. This is based on the formula 2n^2, where n is the orbit number. Therefore, for the second orbit (n=2), it can hold 2*2^2 = 8 electrons.
In a lead atom, the number of electrons in each orbit are as follows: 2 electrons in the first orbit (closest to the nucleus) 8 electrons in the second orbit 18 electrons in the third orbit 32 electrons in the fourth orbit
The Third Principal Energy Level can hold 2 e- in the S orbital and6 e- in the P sublevel. So there's a total of eight e- in all.
The second orbit has 8 electrons.
cloudsAn atom is made of a core + electrons .The core is made of positive charges held together by neutral charges. The electrons, negative charges, orbit round it.If there is 5 positive charges in the core, 5 electrons would orbit around it. Otherwise it's not called an atom anymore, but a ion.
13 electrons are in the third orbit of Manganese.
