What happens when
an element is
oxidised?

Answers

Answer:

The process in which a substance loses an electron in a chemical reaction is called oxidation. The atoms that lost electrons are said to be oxidized. Atoms can be oxidized by nonmetals. Reduction is gain of electrons and thus gaining of negative charge.

An atom with an atomic number of 33 is ionized and found to have a charge of -3. How many electrons in the atom? What is the isotope symbol of this atom ?*

Answers

Explanation:

The element with atomic number of 33 is Arsenic (As)

ionized and found to have a charge of -3.

The negative sign denotes that it gained an electron. So -3 means it gained 3 electrons.

How many electrons in the atom?

Total number of electrons = Number of electrons gained + Electrons in it's neutral state

Total electrons = 3 + 33 = 36

As the amount of charge on two objects increases, the strength of the electrical force between the objects

increases.
decreases.
varies.
remains the same.

Answers

Answer:

Increase is the answer

Explanation:

Increase is the answer hopes this helps you

Given that the amount of charge increases, then, the electrical force between the two objects will also increase

Coulomb's law equation

F = Kq₁q₂ / r²

Where

F is the force of attraction K is the electrical constant q₁ and q₂ are two point charges r is the distance apart

From the Coulomb's equation,

F = Kq₁q₂ / r²

We can see that the force (F) is proportional to the charges (q₁ and q₂).

This simply implies that as q₁ and q₂ increase, F will also increase and as q₁ and q₂ decrease, F will also decrease.

With the above information in mind, we can conclude that the force will increase if the amount of charge on the two objects increases.

Combine Boyle’s law, Charles’s law, and Gay-Lussac’s law into a single proportional relationship between pressure (P), volume (V), and temperature (T). Use the symbol “∝” to represent “is proportional to.”

Explain your reasoning.

Answers

On combing Boyle’s law, Charles’s law, and Gay-Lussac’s law into a single proportional relationship law:

[tex]PV\propto T[/tex]

Explanation:

Boyle's law states that the pressure of the ideal gas is inversely proportional to the volume occupied by the ideal gas at a constant temperature in Kelvins.

             [tex]P\propto \frac{1}{V}[/tex] ( Constant temperature)

Charle's law states that volume occupied by the ideal gas is directly proportional to the temperature of the ideal gas in Kelvins, under constant pressure.

             [tex]V\propto T[/tex]  (Constant pressure)

Gay-Lussac’s law states that the pressure of the ideal gas is directly proportional to the temperature of the ideal gas in Kelvins, under a constant volume.

            [tex]P\propto T[/tex]   (Constant volume)

On combing Boyle’s law, Charles’s law, and Gay-Lussac’s law into a single proportional relationship law we get:

[tex]PV\propto T[/tex]

In the above relation all the three laws; Boyles law, Charles law, and Gay Lussac's laws are followed.

An atom or ion has 43 neutrons , 36 protons, and 36 electrons. Identify the element symbol, and determine the mass number and charge for this atom or ion.

Answers

Answer:

Element name: Krypton

Symbol: Kr

Mass Number: 79 AMU

Charge: 0, electrons and protons cancel out.

ion: none, it is a halogen.

Explanation:

Krypton is the 36th element on the periodic table and has 36 protons. The mass is protons plus nuetrons so 36 + 43 is 79 AMU or Atomic Mass Units.

Answers

Answer:

Explain in terms of atomic structure, why Cesium (Cs) has a LOWER first ionization energy than Rubidium (Rb). Cesium is further down on the periodic table. ... The ion K+1 has one more electron than the atom K. K+1 has lost one electron from its valence shell, and therefore has one less electron shell than K.

Explanation:

Radium contains the most electron shells, which creates a shielding effect that reduces the ionization energy.

Radium:

[tex][Rn]7 S^2[/tex] Layer atomic radius

Calcium:

[tex][Ar]4S^2[/tex] Smaller atomic radius

A higher proportion of electron shells creates a shielding effect, resulting throughout a decreased zeff as well as easier ionization of the outermost election.
