Why 4S orbital is filled before 3d orbital during writing electronic configuration Explain with the help of n l rule?

4s-orbital will be filled prior to 3d-orbital.ORBITALnl(n+l)4s404+0 = 43d323+2 = 5Since 4s-orbital has least value of (n+l), therefore ,it will occupy electrons before3d-orbital.The order of increasing of energy of orbitals can be calc. from(n+l) rule or 'Bohr bury rule' According to this rule, the value of n+l is the energy of the orbital and such on orbital will be filled up first. e.g. 4s orbital having lower value of(n+l) has lower energy than 3d orbital and hence 4s orbital is filled up first. For 4s orbital, n+l=4+0=4 For 3d orbital, n+l=3+2=5,therefore 4s orbital will be filled first.


Is this true or false Osmosis is the process by which molecules tend to move from an area of higher concentration to an area of lower concentration?

True. Osmosis is the process by which solvent molecules (usually water) move across a semi-permeable membrane from an area of higher concentration to an area of lower concentration in order to equalize the concentration on both sides of the membrane.


What is the movement of molecules from greater to lower?

This movement is called diffusion, where molecules move from an area of higher concentration to an area of lower concentration in order to achieve equilibrium. The process is driven by the random motion of molecules and does not require energy input.


Why does passive diffusion occur?

Passive diffusion occurs because molecules move from an area of higher concentration to an area of lower concentration, in order to reach equilibrium. This process does not require the input of energy.


The order in which atomic orbitals are filled is based on what factor?

It is based on many factors, but the easiest to understand is ENERGY. The orbitals in which the electron has the lowest energy are filled FIRST.

What motivational theorist is associated with the following assumption before higher level needs can be addressed or acted on owners lower needs must be met?

This assumption is associated with Abraham Maslow's theory of hierarchy of needs. Maslow proposed that individuals must first satisfy their lower-level physiological and safety needs before progressing to higher-level needs like social belonging, esteem, and self-actualization. This hierarchy suggests that individuals are motivated by unmet needs in a sequential order.


Is a molecule with a higher bond order more stable than a molecule with a lower bond order?

Yes, a molecule with a higher bond order is generally more stable than a molecule with a lower bond order.

What is Maslowe's hierarchary?

Maslow's hierarchy of needs is a theory in psychology that suggests individuals are motivated to fulfill certain needs in a specific order: physiological, safety, love/belonging, esteem, and self-actualization. It proposes that once lower level needs are met, individuals are motivated to satisfy higher level needs.


What do modern psychologists believe about the hierarchy of human needs?

Modern psychologists, like Abraham Maslow, believe in a hierarchy of human needs, with basic physiological needs at the base (such as food and shelter) and higher-order needs like self-actualization at the top. They suggest that individuals must fulfill lower-level needs before addressing higher-level ones. This theory has been influential in understanding human motivation and behavior.


What is the relationship between religion and social order in Egypt?

Define of Maslow's hierarchy of needs?

Maslow's hierarchy of needs is a psychological theory that categorizes human needs into five levels: physiological, safety, love/belonging, esteem, and self-actualization. According to the theory, individuals prioritize fulfilling lower-level needs before moving on to higher-level needs.


What must change in order for the pitch of a sound change?

The frequency of the sound wave must change in order to change the pitch of a sound. A higher frequency results in a higher pitch, while a lower frequency results in a lower pitch.


What is lower order thinking skills?

Lower order thinking skills include knowledge, memorization and comprehension. These skills are required to move into a higher order thinking. These skills are taught in school systems.


What does this bond-order difference mean in terms of bond energy?

A higher bond order indicates stronger bonding and higher bond energy. Conversely, a lower bond order signifies weaker bonding and lower bond energy. Bond order directly affects the strength of a bond and the energy required to break it.


Why are higher order concerns and lower order concerns important?

Higher order concerns and lower order concerns are the two areas a professional content editor checks. These two broadly classified areas help the editor to rate the academic related essays and grade the level of writing. The higher order concerns help the editor to find out if the author of the essay or any content has included the thesis statement, focus to the main idea of the essay, if the content is appropriate for the audience and serves the purpose, if the ideas are better organized and developed in the order of importance. The lower order concerns help the editor to check the sentence structure, punctuation, spelling errors, and word choice.


How does maslows hierarchy of needs relate to communication?

Maslow's hierarchy of needs suggests that individuals have certain needs that must be met in a particular order, starting from basic physiological needs to self-actualization. In terms of communication, meeting the lower-level needs such as safety and belongingness can enhance communication effectiveness as individuals feel secure and connected, allowing them to focus on higher-level communication goals. Effective communication can also help fulfill higher-level needs such as self-esteem and self-actualization by providing opportunities for self-expression and personal growth.
