What is in the space between the nucleus and electrons?
The empty space between the atomic cloud of an atom and its nucleus is just that: empty space, or vacuum. Electrons are thus ‘spread out’ quite a bit in their orbits about the nucleus. In fact, the wave-functions for electrons in s-orbitals about a nucleus actually extend all the way down into the nucleus itself.
What is the pattern of electron?
You should see two patterns, or trends: Elements in the same Group have the same number of valence shell electrons. Across a period of the Periodic Table from left to right the number of valence electrons increases.
What is the space around the nucleus called?
Answer: [C] Orbital. Notes: The region of space around the nucleus where the probability of finding an electron is maximum is called an orbital. The electron cloud is a visual model that represents all the orbitals in an atom.
Which subshell can hold the greatest number of electrons?
d subshell
The d subshell can hold a maximum of 10 electrons.
What is the nucleus made up of?
Atomic nuclei consist of electrically positive protons and electrically neutral neutrons. These are held together by the strongest known fundamental force, called the strong force. The nucleus makes up much less than . 01% of the volume of the atom, but typically contains more than 99.9% of the mass of the atom.
Why do electrons dance around the nucleus of an atom?
As the electrons in one atom get close enough to the nucleus of the other, the patterns of their dances change. This is because, an electron in a low energy level around one nucleus can’t do the same around the other – that slot’s already taken by one of its own electrons.
Why are electrons balanced in the normal state of an atom?
Because an atom in its normal state is electrically neutral, each electron in an atom must be balanced by the same amount of positive charge. The next step was to determine where in the atom the positive and negative charges are located.
Why do electrons move in a set pattern?
In fact, electrons dance – there is no better word for it. But it’s not random dancing – it’s more like ballroom dancing, where they move in set patterns, following steps laid down by a mathematical equation named after Erwin Schrödinger.
Why do electrons orbit the centre of an atom?
Unfortunately, much of what we are taught at school is simplified – electrons do not orbit the centre of an atom like planets around the sun, like you may have been taught. Instead, think of electrons like a swarm of bees or birds, where the individual motions are too fast to track, but you still see the shape of the overall swarm.
