Group of elements with the same number of valence electrons

Physics
1 answer:
bekas [8.4K]3 years ago
4 0

Therefore, elements whose atoms can have the same number of valence electrons are grouped together in the periodic table of the elements. As a general rule, a main group element (except hydrogen or helium) tends to react to form a closed shell, corresponding to the electron configuration s2p6.

What type of material is thought to explain the larger size of the outer planets relative to the inner planets
svetoff [14.1K]

The material which is believed to explain the larger size of the outer planet in relation to the inner planet is gas while the inner is made of rock

Research on the solar system reveal to us that it is temperature of the the solar system that perfectly explain the materials both the outer and inner planets are made up of. The outer part is highly gaseous while the inner part is made of rocks

<h3>What is outer planet?</h3>

It refers to planet whose orbit lies outside the asteroid belt. Examples include Jupiter, Saturn, Uranus, or Neptune.

<h3>What is inner planet?</h3>

This simply means a planet whose orbit lies within the asteroid belt. They are planets such as Mercury, Venus, Earth, or Mars.

When you throw a pebble straight up with initial speed V, it reaches a maximum height H with no air resistance. At what speed sh
aev [14]

Answer:

Explanation:

Given

Initial speed is u=V

Maximum height of Pebble is H

Deriving maximum height of Pebble and considering motion in vertical direction

v^2-u^2=2 as

where v=final velocity

u=initial velocity

a=acceleration

s=Displacement

Final velocity will be zero at maximum height

0-(V)^2=2\times (-g)\cdot H

H=\frac{V^2}{2g}

i.e. maximum height is dependent on square of initial velocity

for twice the height

2H=\frac{(V')^2}{2g}

on comparing

V'=\sqrt{2}V

a mass on a spring vibrates in simple harmonic motion at an amplitude of 8.0 cm. if the mass of the object is 0.20kg and the spr
Reil [10]

Answer:

4.06 Hz

Explanation:

For simple harmonic motion, frequency is given by

f=\frac {1}{2\pi}\times \sqrt{\frac {k}{m}} where k is spring constant and m is the mass of the object.

Substituting 0.2 Kg for mass and 130 N/m for k then

f=\frac {1}{2\pi}\times \sqrt{\frac {130}{0.2}}=4.057670803\\f\approx 4.06 Hz
