The position of electrons in orbitals is not an exact science; orbitals are places where the electrons should be 99% of the time and electrons are not just single points in that area which orbit like a planet. They twist and move around each other, but are not blown away because of the electric force holding them in.
They do repel each other. Just not strongly enough to overcome the attractive force each of the electrons have for the nucleus.
More precisely, the energy required to knock one of the electrons out of a specifric orbital is more than one electron in that same orbital can provide.
"Opposites attract". So two electrons repel each other.
There are no unpaired electrons in calcium, all 20 electrons are in pairs, i.e. each pair is configured in one orbital: 2x in 1s orbital 2x in 2s orbital 2x in each of the three 2p orbitals 2x in 3s orbital 2x in each of the three 3p orbitals and 2x in 4s orbital (these two are the valence electrons)
The 2p sub-level can hold a maximum of 6 electrons. The 2p sub-level is divided into 2px, 2py and 2pz. Each of those orbitals can hold a maximum of 2 electrons. There are 3 of them and thus 6 total for the 2p sub-level.
17
because sublevel p has 3 orbital and each orbital can hold up to 2 electrons meanwhile sublevel s only has 1 orbital and each can hold 2 electrons therefore sublevel p can hold more
yes
The electrons of the two atoms interact with each other and distort their orbital shapes
"Opposites attract". So two electrons repel each other.
Repel each other
they carry same charge thus repel as opposites attract each other
1) what is electron? 2) what is matter? 3) structure of atom?
no
Repel, because like charges repel each other
Two magnets that are pointing in the same direction along side of each other will repel. They do this because their charges are the same. This is basically what electrons do because opposites attract and two charges that are the same will repel.
yes. all particles with like charges repel each other.
Each electron has a single negative charge. Objects with like charges repel each other. Therefore two electrons following parallel tracks will repel, not attract, each other.
The negative charges of their electrons repel each other.
