What is required for electrons to move from the stable energy level to an excited state?

Chemistry

answer

When an electron temporarily occupies an energy state greater than its ground state, it is in an excited state. An electron can become excited if it is given extra energy, such as if it absorbs a photon, or packet of light, or collides with a nearby atom or particle

What are the characteristics of electromagnetic waves?
CaHeK987 [17]

Answer: Electromagnetic waves are transverse in nature as they propagate by varying the electric and magnetic fields such that the two fields are perpendicular to each other.

Accelerated charges are responsible to produce electromagnetic waves.

In an atom, the number of neutrons determines most specifically the ________.
lord [1]

In an atom, the number of neutrons determines most specifically the isotopes of an element.

<h2>Further Explanation</h2><h3>An atom  </h3>
  • An atom is defined as the smallest particle of an element that can take part in a chemical reaction.
  • Atoms are made of energy shells and the inner nucleus.
  • It is also made up of subatomic particles, protons and neutrons.
<h3>Neutrons  </h3>
  • They are sub-atomic particles in an atom that are found in the nucleus of an atom. They have a zero charge or no charge.
  • Neutrons are slightly heavier than protons.
  • The number of protons and neutrons in a nucleus of an atom results to the atomic mass number of an atom. Like protons they only take part in nuclear reactions.
<h3>Protons</h3>
  • Protons are subatomic particles that are found in the nucleus of an atom. They are positively charged. with a charge of +1.
  • The number of protons differ from one element to another and thus used as the atomic number of an individual element.
  • The nucleus of an atom is positively charged due to the positive charge of the protons.  
  • Additionally, protons do not take part in chemical reactions but in nuclear reactions.
<h3>Electrons  </h3>
  • They are found orbiting the nucleus on energy shells based on Clouds’ theory. Electrons are negatively charged each with a charge of -1.
  • The number of electrons and protons in a neutral atom are equal. Additionally they have the least mass of the three sub-atomic particles.
  • Electrons are the only sub-atomic particles that take part in chemical reactions.
<h3>Isotopes </h3>
  • Isotopes are atoms of the same element that have the same mass number but different atomic number.
<h3>Mass number;</h3>
  • Mass number is the sum of the number of protons and neutrons in the nucleus of an atom of an element.

Keywords: Atom, sub-atomic particles, electrons, protons, neutrons, isotopes

A gas cylinder is filled with argon at a pressure of 177 atm and 25°C. What is the gas pressure when the temperature of the cyli
Elena L [17]

277.79 atm is the calculated gas pressure.

The ideal gas is a fictitious concept used to study how real gases behave by comparing them to their deviations. The pressure-temperature rules are followed by an ideal gas.

177 atm is the initial pressure. The starting temperature is 298 K (25 °C = 25 + 273 °C).

195°C = 195+273

= 468K is the final temperature.

The pressure temperature relation illustrated below can be used to get the final pressure.

P1/T1 = P2/T1

= P1T2/T1

= 177 atm 468 K /298 K

= 277.97 atm

The final pressure is therefore 277.97 atm.
