Which element has an outer(ending) electron configuration of s2p4?

Answers

The question is in complete, the complete question is:

Which element has an outer electron configuration of s 2 p4 ?

(A) Ca (B) Cr (C) Ge (D) Se

Answer:

(D) Se

Explanation:

The outer electronic configuration of an atom reflects the group to which it belongs in the periodic table. Each group has its unique outermost electron configuration and number of electrons found in the outermost shell of the atoms of elements in the group.

s 2 p4  is the unique outermost electron configuration of group 16 elements. Group 16 elements have six electrons in their outermost shell. If we consider the options, only Se is a member of group 16. Hence it is only Se that has the outermost electron configuration s 2 p4 .

An element which has an outer (ending) electron configuration of [tex]s^2p^4[/tex] is: Oxygen.

Electron configuration can be defined as a formula that is used to denote the distribution of the atoms of a chemical element in an atomic orbital.

Basically, electron configuration uses four (4) main letters to illustrate the distribution of atoms in an atomic orbital:

spdf

The electron configuration of [tex]s^2p^4[/tex] indicates that the chemical element is in Group 6 and has six (6) electrons in its outermost shell.

Hence, a chemical element such as Oxygen (O) or Selenium (Sn) in Group 6 of the periodic table would have an electron configuration of [tex]s^2p^4[/tex].

How is the term stable used in the text?

Answers

Answer:

When something is stable, it's fixed and steady. If you needed advice, you'd probably go to your most stable friend, the one least likely to act crazy or be easily upset.

Explanation:

Whether you're talking about an object or a person, the adjective stable implies reliability and strength. You can describe a government as stable, or a relationship, or a desk. A completely different meaning of stable is the noun "building used for housing horses or other animals." Both senses of the word come from the Latin stabilis, "firm or steadfast."

According to this question, each model of molecules in the options contains spheres of different colors and sizes representing different types of atoms. The atoms of the same element are the spheres of same color and size while atoms of different element are of different color or size.

Therefore, the model showing a molecule of a substance that is made up of three elements is model D because it is made up of three distinct spheres representing atoms of each element.

Which of the following situations best describes an ionic bond?
Two atoms each give up an electron, and an electrostatic force attracts them.
One atom gains an electron while the other atom loses an electron, and an
electrostatic force attracts them.
One atom gains an electron while the other atom loses an electron, and an
electrostatic force repels them.
Two atoms gain electrons and an electrostatic force attracts them.

Answers

One atom gains an electron while the other atom loses an electron and a electrostatic force attracts them.

The situation which best describes the ionic bond is “ One atom gains an electron while the other atom loses an electron, and an electrostatic force attracts them”.

What is an ionic bond?

An ionic bond is formed between two atoms by donating an electron from the electropositive atom and withdrawal of that electron by the second atom which is electronegative and thereby attaining stability by making their valency completed.

The electron loss-gain interaction make an electrostatic force of attraction between them, where the electrons from the electropositive atom is attracted towards the electronegative atom.

Thus the two atoms are bound together by the electrostatic force of attraction created by the electron donation. Hence, option b is correct.

Your advisor has given you a tube of GMP that has been sitting in the freezer for many years and wants to know the concentration. There is one problem: the spectrophotometer in the lab has been 'optimized' for use with proteins and only measures at 280 nm. You decide to give it a try. After getting and absorbance reading of 0.2, what is the concentration of GMP in the tube (assuming a 1 cm path length).

Answers

Answer:

2.22 × 10^-5M

Explanation:

From Beer-Lambert's law;

A=εcl

Where A = absorbance of GMP= 0.2

ε= molar extinction coefficient of GMP = 9000 M-1cm-1

c= concentration of GMP= the unknown

l= path length = 1 cm

c= A/εl = 0.2/ 9000 M-1cm-1 × 1 cm

c= 2.22 × 10^-5M

Question 1 of 10 What is molarity a measurement of? O A. The volume of liquid containing a dissolved substance B. The grams of a substance dissolved in a liquid O c. The concentration of a substance dissolved in a liquid O D. The number of moles of a dissolved substance

Answers

To do this measure called molarity is commonly used. Molarity (M) is defined as the number of moles of solute (n) divided by the volume (V) of the solution in liters. It is important to note that the molarity is defined as moles of solute per liter of solution, not moles of solute per liter of solvent.                    

so the answer is D.

hope this helps have a great day....!

According to the concept of molar concentration, molarity is  defined as the number of moles of a dissolved substance.

What is molar concentration?

Molar concentration is defined as a measure by which concentration of chemical substances present in a solution are determined. It is defined in particular reference to solute concentration in a solution . Most commonly used unit for molar concentration is moles/liter.

The molar concentration depends on change in volume of the solution which is mainly due to thermal expansion. Molar concentration is calculated by the formula, molar concentration=mass/ molar mass ×1/volume of solution in liters.

In terms of moles, it's formula is given as molar concentration= number of moles /volume of solution in liters.

Rank lead, phosphorus, and barium in order of increasing ionization energy.
A) Pb < P < Ba
B) Ba < P < Pb
C) Pb < Ba < P
D) Ba < Pb < P

Answers

Answer:

D) Ba < Pb < P

Explanation:

Barium (Ba): 5,2117

Lead (Pb): 7,4167

Phosphorus (P): 10,4867

Increasing order of ionization energy:

Ba < Pb < P

Electronic configurations of given elements

Pb: [Xe] 6s² 4f¹⁴ 5d¹⁰ 6p²

P:   [Ne] 3s² 3p³

Ba: [Xe] 6s²

All the given elements have stable half-filled subshells. But phosphorus has the smallest atomic size among them, so it will have the lowest tendency to remove an electron from its valence shell and hence will require the highest amount of ionization energy.  Barium has a higher atomic size than lead, therefore it has lower ionization energy than lead.

How are ionization energy and atomic size related?The force of attraction is stronger when the electron is closer to the nucleus, and as a result, more energy is needed to overcome this attraction and remove the electron.Therefore, the ionization energy increases with decreasing radius and vice versa.
