The neucles is surrounded by electrons. Electrons occupy most of the volume of the atom.

Atomic Model:

Atoms are the smallest unit of elements, which form bonds with others. In an atom, electrons revolve around the nucleus.

The nucleus is composed of positively charged protons and neutrons. The nucleus occupies a very small part of the atom.

Electrons are negatively charged particles, they are found around the nucleus and occupy most of the part of the atom.

Therefore, The neucles is surrounded by electrons. Electrons occupy most of the volume of the atom.

Answer: When I see you again!

Explanation:

Answer:

Explanation:

While trying to write the chemical formula for a compound (a neutral molecule), one must identify and exchange the charge of the cation with that of the anion to become the subscript of one other. For example

Aluminium oxide has Aluminium (Al) and oxygen (O); since Al has a charge of 3+ (the cation) and O has a charge of 2- (the anion), the compound would have it's charges as Al³⁺O²⁻ and when the charges are exchanged to there subscripts, it would form Al₂O₃; thus there would be two cations of aluminium for every three anions of oxygen in order to have a neutral molecule.

This same explanation can be given to Aluminium sulfite. Aluminium sulfite has Aluminium (Al) and sulfite (SO₃). Al has a charge of 3+ (cation) while sulfite has a charge of 2- (anion), with the compound having it's charges as Al³⁺(SO₃)²⁻ and when the charges are exchanged to there subscripts, it would form Al₂(SO₃)₃ and would thus have 2 cations of aluminium (Al³⁺) for every 3 anions of sulfite (SO₃³⁻) in order to have a neutral molecule.

Explanation:

Distillation is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. Distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases the concentration of selected components in the mixture. In either case, the process exploits differences in the relative volatility of the mixture's components. In industrial applications, distillation is a unit operation of practically universal importance, but it is a physical separation process, not a chemical reaction.

The correct Lewis dot structure for [tex]BeH_2[/tex] is Be : H : H

The Lewis dot structure shows the valence electrons as dots. The valence electrons of beryllium are shown as 2 dots on the left side of the atom.

The central atom, beryllium, has 2 valence electrons where each hydrogen atom has 1 valence electron. To form a stable molecule, beryllium shares its 2 valence electrons with the 2 hydrogen atoms, each of which shares its 1 valence electron with beryllium which gives each atom a full outer shell of electrons.

Balanced equation : C. CH₄ + 4Cl₂⇒  CCl₄+ 4HCl

Equalization of chemical reactions can be done using variables. Steps in equalizing the reaction equation:  

1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.  

2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product  

3. Select the coefficient of the substance with the most complex chemical formula equal to 1  

Reaction

CH₄ + Cl₂⇒  CCl₄+ HCl

aCH₄ + bCl₂⇒  CCl₄+ cHCl

C, left=a, right=1⇒a=1

H, left=4a, right=c⇒4a=c⇒4.1=c⇒c=4

Cl, left=2b, right=4+c⇒2b=4+c⇒2b=4+4⇒2b=8⇒b=4

The equation becomes :

CH₄ + 4Cl₂⇒  CCl₄+ 4HCl

Answer:

0.86 moles of CO₂

Explanation:

Given data:

Number of atoms of CO₂ = 5.2×10²³ atom

Number of moles = ?

Solution:

Avogadro number:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ atoms

5.2×10²³ atom× 1 mol / 6.022 × 10²³ atoms

0.86 mol

The frequency(f) of this photon : 1 x 10¹⁵ Hz

Radiation energy is absorbed by photons

The energy in one photon can be formulated as

[tex]\large{\boxed{\bold{E\:=\:h\:.\:f}}}[/tex]

Where

h = Planck's constant (6,626.10⁻³⁴ Js)

f = Frequency of electromagnetic waves

f = c / λ

c = speed of light

= 3.10⁸

λ = wavelength

A photon has a wavelength of 299 nm.

λ = 299 nm = 299 x 10⁻⁹ m = 2.99 x 10⁻⁷ m

The frequency  :

[tex]\tt f=\dfrac{3.10^8}{2.99\times 10^{-7}}\\\\f=\boxed{\bold{1\times 10^{15}~Hz}}[/tex]

Answer:

Chemists keep track of how electrons are transferred between atoms in a reaction using an oxidation number. If the oxidation number of an element in the reaction increases or becomes less negative, the element has been oxidized, while a decreased or more negative oxidation number means the element has been reduced.

Answer:

Because the intermolecular interactions are weaker.

Explanation:

Nonpolar substances do not have dipole-dipole or hydrogen bond interactions, which are strong intermolecular interactions that often make the substance liquid or solid. Instead, they must rely on van der Waals forces, which are relatively weaker interactions that are often insufficient to hold the molecules together in liquid or solid form.

The magnitude of intermolecular association in nonpolar substance is much lower than the magnitude of intermolecular association in polar substances.

Polar substances are those substances in which a permanent dipole exists in the molecule. In a molecule having a permanent dipole, the electronegativity difference between the atoms bonded in the molecule is high.

As a result of this high electronegtivity difference between atoms, the molecules interact more intimately hence polar molecules tend to exist mostly as liquids and gases while nonpolar molecules having less intimate intermolecular interaction via dispersion forces exist mostly as gases.
