Electron movement in the bonding of Group ___ elements with Group 7A elements is best described as ______________

Physics
2 answers:
spin [16.1K]3 years ago
8 0

Answer:

<h2>Group 1A</h2><h2>Ionic bond or electrostatic bond</h2>

Explanation:

  • Bond is a type of energy that is responsible to hold two or more same or different types of atoms.
  • On the basis of bond formation, the bond may be an ionic bond, covalent bond, coordinate bond and some other.  
  • Group 7A elements like chlorine, bromine and some other has 7 electrons in its outermost shell so it receives 1 electron to complete its octet and thus the formation of chloride or other ions takes place having a negative charge.
  • So 1A group like sodium and some other has 1 electron in its outermost shell and thus loses 1 electron to obtain octane and thus form a positive ion.  
  • Thus attraction takes place between positive ions like sodium ions and negative ions like chloride ions and a bond is formed that is known as an ionic bond or electrostatic bond.

How do we know the sun rotates?
Eduardwww [97]
Hi pupil Here's your answer ::::


➡➡➡➡➡➡➡➡➡➡➡➡➡

The sun Doesnt rotates as we know all . But it rotates with the wjole our Milky Way Galaxy. This movement is so slow that we cant even recognise that we are shifted.

This we know because we all had studied about the solar system and space.

By this study we can say that Sun Rotates.

Who invented the wedge simple machine and why?
Lelu [443]

Answer:

Gene Sarazen began to win tournaments in 1935 with a new club he had invented that was specialized for sand play. He is hailed as the inventor of the sand wedge.

Explanation:

A wedge is a triangular shaped tool, and is a portable inclined plane, and one of the six classical simple machines. It can be used to separate two objects or portions of an object, lift up an object, or hold an object in place. It functions by converting a force applied to its blunt end into forces perpendicular (normal) to its inclined surfaces. The mechanical advantage of a wedge is given by the ratio of the length of its slope to its width.[1][2] Although a short wedge with a wide angle may do a job faster, it requires more force than a long wedge with a narrow angle.

The force is applied on a flat, broad surface. This energy is transported to the pointy, sharp end of the wedge, hence the force is transported.

The wedge simply transports energy and collects it to the pointy end, consequently breaking the item. In this way, much pressure is put on a thin area.

A penny rides on top of a piston as it undergoes vertical simple harmonic motion with an amplitude of 4.0cm. If the frequency is
aniked [119]

1) At the moment of being at the top, the piston will not only tend to push the penny up but will also descend at a faster rate at which the penny can reach in 'free fall', in that short distance. Therefore, at the highest point, the penny will lose contact with the piston. Therefore the correct answer is C.

2) To solve this problem we will apply the equations related to the simple harmonic movement, hence we have that the acceleration can be defined as

a = -\omega^2 A

Where,

a = Acceleration

A = Amplitude

\omega= Angular velocity

From a reference system in which the downward acceleration is negative due to the force of gravity we will have to

a = -g

-\omega^2 A = -g

\omega = \sqrt{\frac{g}{A}}

From the definition of frequency and angular velocity we have to

\omega = 2\pi f

f = \frac{1}{2\pi} \sqrt{\frac{g}{A}}

f = \frac{1}{2\pi} \sqrt{\frac{9.8}{4*10^{-2}}}

f = 2.5Hz

Therefore the maximum frequency for which the penny just barely remains in place for the full cycle is 2.5Hz
