How dose an atom change if all of its electrons are removed

Physics
1 answer:
cluponka [151]3 years ago
7 0

Answer:

The atom becomes a positively charged ion.

Explanation:

  1. The building blocks of an atom are protons, neutrons, and electrons.
  2. The protons and neutrons present in the core of the atom are called nucleus.
  3. The electrons are scattered in an ordered way around the nucleus.
  4. The protons are positively charged and the electrons are negatively charged particles. The neutrons do not possess any charges.
  5. Binding energy is supplied to the atom to remove an electron.
  6. It is possible to remove the electrons of the lighter elements.
  7. When an electron is removed from the hydrogen atom. It becomes positively charged ion or simply proton.
  8. When all of the electrons are removed from the helium atom, it becomes a positively charged α particle.
  9. It is practically very difficult to remove all of the electrons from the heavier elements.
  10. When all of the electrons are removed from an atom it becomes an unstable positively charged ion.

Answer:

Static friction

Explanation:

When there is contact between two surfaces and there is no movement, there is static friction. So, if we have a book that rests on a wooden table, we have an example of Static friction, where this force avoids the movement of the book.

calculate the electric field strength between two parallel plates separated by 0.50 cm, across which is a potential of 12 volts.
Alexxandr [17]
Formula for Electric Field strength , E =  V/d

where V = Voltage in volts, and d = distance of separation in meters.

d = 0.5 cm = 0.005 m,    V = 12 V

E = V/d =  12 / 0.005

E = 2400

Electric Field Strength = 2400 Volts/meter

A book falls off a shelf that is 10.0 m tall. What is the velocity at which the book hits the ground?
Elena L [17]

Answer:

14 m/s

Explanation:

The motion of the book is a free fall motion, so it is an uniformly accelerated motion with constant acceleration g=9.8 m/s^2 towards the ground. Therefore we can find the final velocity by using the equation:

v^2 = u^2 + 2gd

where

u = 0 is the initial speed

g = 9.8 m/s^2 is the acceleration

d = 10.0 m is the distance covered by the book

Substituting data, we find

v=\sqrt{0^2 + 2(9.8 m/s^2)(10.0 m)}=14 m/s

A disk is uniformly accelerated from rest with angular acceleration α. The magnitude of the linear acceleration of a point on th
solniwko [45]

Answer:

a = R\alpha\sqrt{1 + \alpha^2t^4}

Explanation:

As we know that the acceleration of a point on the rim of the disc is in two directions

1) tangential acceleration which is given as

a_t = R\alpha

2) Centripetal acceleration

a_c = \omega^2 R

here we know that

\omega = \alpha t

a_c = (\alpha t)^2 R

now we know that net linear acceleration is given as

a = \sqrt{a_c^2 + a_t^2}

so we have

a = \sqrt{R^2\alpha^2 + R^2(\alpha t)^4}

a = R\alpha\sqrt{1 + \alpha^2t^4}
