Why are valence electrons important when considering the bonds that form between atoms g

1 answer:

7 0

Answer:Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell. By sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability.

Under identical conditions of temperature and pressure, which of the following gasses is the densest: Ne, CO2, or Cl2?

Tanzania [10]

Cl2=3.17g/L
Ne=.901g/L
CO2=1.96g/l
therefore Cl2 is the densest gas under the given conditions.

Force develops when two solutions each different concentration solutes separated semipermeable membrane

Zarrin [17]

Answer is: osmotic pressure.
Osmotic pressure, alongside the vapor pressure depression, freezing point depression and the boiling point elevation are the colligative properties od solution.
The direction of osmotic pressure is always from the side with the lower concentration (c = n/V) of solute to the side with the higher concentration.

A single atom of an element has 11 protons, 11 electrons, and 12 neutrons. Which element is it?

scoray [572]

Answer:

Explanation:

When identifying elements, you only need to look at the number of protons. Elements can have varying numbers of electrons and neutrons, but they can only have one number of protons.

Looking at the periodic table, the elements with 11 protons is sodium (Na).

The gravitational force between which two objects would be the most difficult to notice? A. The moon and the earth b. The moon a

Ghella [55]

Answer:

d. A water particle and an air particle

Explanation:

The force of gravity (F) between two objects of masses m1 and m2 and separated by a distance r is given as:

$F = G\frac{m1*m2}{r^{2} }$

where G is the gravitational constant

This force is therefore, directly proportional to the masses and inversely related to the distance between them.

Based on the given options, since the masses of the water and air particles are very small (masses of earth, moon and sun is relatively huge), the gravitational force between them would be negligible and difficult to measure.
