Because of the electromagnetic force. It requires more energy to pull a negatively charged electron further away from the positively charged nucleus.

What is the state of matter when electrons are stripped away from the nuclei?
When electrons are stripped away from the nuclei, the state of matter is in the form of a plasma. Plasmas are ionized gases consisting of positive ions and free electrons. They are commonly found in stars, lightning, and some man-made devices like plasma TVs.
What causes electrons to flow through a conductor?
There are 1 to 3 electrons in outer orbit of a conductor witch the element wants to give away in order to have inner orbit complete at the cost of getting positive charge when forced by the electric voltage.If outer orbit have 4 electrons like carbon,silicon or germanium, it acts as a semiconductor. And if outer orbit have more than 5 electrons, it will resist electron flow.
How do you get the number of neutrons in a element?
To find the number of neutrons in an atom you would subtract the protons from the atomic mass. The number of protons is equal to the atomic number. When dealing with an element with no net charge, the atomic number = the number of protons and also the number of electrons. The atomic mass - the atomic number (number of protons and electrons) = the number of neutrons
What is the relationship between the atomic radius of an element and its position on the periodic table?
The atomic radius of an element generally decreases as you move from left to right across a period on the periodic table. This is because the number of protons and electrons increases, leading to a stronger attraction between the nucleus and the outer electrons, causing the atomic radius to decrease. However, the atomic radius tends to increase as you move down a group on the periodic table due to the addition of new energy levels, which results in the electrons being further away from the nucleus.
Why is extremely high pressure required to cause atomic nuclei to crash into one another?
Extremely high pressure is required for fusion to occur because the electromagnetic force would otherwise cause the protons in the two nuclei to repel each other, and you need to overcome that repulsive force, and allow the stronger1 binding energy to take over.Not asked, but answered for completeness; you also need extremely high temperature because you need to strip the electron clouds away, i.e. to fully ionize the nuclei, to eliminate interference from the electrons as well.-------------------------------------------------------------------------------------------------1 The binding energy is stronger, but only at closer distances. Outside the radius of the nucleus, the electromagnetic force is more powerful, hence the need for pressure. Once inside the radius of the nucleus, at least for elements smaller than lead, the binding energy is more powerful.
What is the state of matter electrons are electrons are stripped away from the nuclei?
Plasma

Why do elements on the left side of the periodic give away electrons?
The attraction between the atomic nucleus and electrons is less strong.
Does the inner or outer orbits hold more electrons?
The inner orbits (closer to the nucleus) hold fewer electrons than the outer orbits. Each orbit has a maximum capacity of electrons it can hold based on its energy level. The further away an orbit is from the nucleus, the higher its energy level and the more electrons it can hold.
Why metal is the best conductor of heat and electricity?
You have configuration of the elements. There can be eight electrons in the outermost orbit of the element. The metals have one, two or three electrons in the outermost orbit. So they want to give away those extra electrons. These are free electrons. These free electrons make the metals good conductors of heat and electricity.
What information does the atomic number of an element give you?
The atomic number is how many protons there are, and since the number of protons is equal to the number of electrons, it is also the number of electrons. You can take the number of protons away from the atomic weight (overall weight) which will give you the number of neutrons. (Electrons don't weigh anything in the atomic weight so you don't need to subtract this as well). Hope this helps :D
Elements like francium located at the bottom of a group have a lower attraction for their valence electrons because they have a?
higher atomic number and larger atomic size, causing their valence electrons to be farther away from the nucleus, resulting in a weaker attraction. Additionally, the shielding effect of inner electron shells reduces the effective nuclear charge felt by the valence electrons, further decreasing the attraction.
How does electrons shielding affect atomic size as you move down the group?
Shielding affect acts as a barrier for proton to attract electrons, therefore the electrostatic force (the which attracts electrons to protons) becomes much less and electrons become further away from the nucleus of the atom. Because of this, the atomic size increases as you move down the group.
What is the formula to get the number electrons?
First you would calculate the number of protons... the number of protons = the total mass number then the number of protons should = the nummber of electrons(unless their is a number in front of the element like +1) therefore= # of protons = # of electrons

Why ionization energy decreases from top to bottom in a group?
as atomic number is increase the size of the atom goes on increasing as more number of electron is added to the outer most orbit so the nuclear force exerted by the nucleus on electron is less so the affinity to loose electorn is more as the atomic number is increase that is the reason ionization energy decrease with increase in atomic number
