The noble gases are sondal (So), nobble (N), leptum (L), and drogon (Dr). Among these gases, nobble has the greatest atomic mass and sondal the least. Drogon is lighter than leptum. The metal elements in the most reactive group are bruan (Bn), byzmium (By), wondit (Wo), and xakbill (X). Among these metals, wondit has the lowest atomic mass. Xakbill is in the same period as nobble.
Tapstrom (Tp), romulon (Ro), and kritt (Kt) are nonmetals whose atoms typically gain or share one electron. Romulon is in the same period as xakbill and nobble.
The metalloids are effsit (E), hioo (Hi), terrabim (Tm), and syssyss (Ss). Among these metalloids, syssyss has the greatest atomic mass and effsit the least. Hioo and terrabim are in Group 14. Terrabim has more protons than hioo. Yahtza (Yz) touches the zigzag line, but it's a metal, not a metalloid.
The lightest element is iostrom (Io). The heaviest element in the group of 30 elements is elephantum (El). The most chemically active nonmetal is tapstrom. Kritt reacts with byzmium to form table salt.
Begone (Bg) has only four protons.
Flixmit (Fx) is important in the chemistry of life. It forms compounds made of long chains of atoms. Rix (Rx) and dortador (Do) are metals in the fourth period, and rix is less reactive than dortador.
Moonstype (M), golby (G), and syssyss are in Group 15. Golby has fewer electrons than moonstype.
Upra (Up), oziim (Oz), and nuotey (Nu) gain two electrons each when they react. Nuotey has two electron shells and has the same properties as a gas found in Earth’s atmosphere. Oziim has a lower atomic number than upra.
Faltuum (Fa) has 49 electrons. Zippr (Z) and picon (Pi) lose two electrons each when they react. Zippr is used to make lightweight alloys.

why many students visually perceive stem as a vapid class?

for many students, however, stem subjects are optically discerned as vapid, tedious, and destitute of authentic-world applications. science and math have always been a major part of the high school curriculum, but many students have disengaged from these subjects because they don’t optically discern that they have any pertinence to the authentic world or students’ daily lives. for them, math and science have become a set of rules, procedures, laws, theorems, and formulas to memorize. some students even develop math apprehensiveness and cerebrate they are incapable of learning higher-level mathematics.

why is stem paramount?

as the u.s. economy changes, the ordinant dictation for stem-capable workers is growing. in may of 2014, the u.s. bureau of labor statistics counted more than 8.3 million stem jobs, which accounted for 6.2 percent of total employment in the cumulated states. that number is expected to perpetuate to increment as u.s. companies grow and innovate to compete in the ecumenical economy. according to the u.s. department of labor, the average salary for all stem jobs is $85,570, which is virtually double the average salary for all jobs.

many people still envision stem professionals as wearing a white lab coat and conducting research in a laboratory. in authenticity, some of the most in-demand stem fields are petroleum engineering, process engineering, and computer engineering. these fields that are experiencing shortages of qualified candidates are additionally among the highest paying, with the average petroleum engineer earning an annual salary of $147,520 in may 2014 according to the u.s. bureau of labor statistics.

in additament, stem subjects edify students valuable skills that are vital for prosperity in all vocations, even those that do not directly require stem erudition. engagement in stem subjects avails students develop quandary-solving, critical mentally conceiving, and leadership skills. these skills are so ecumenical, in fact, that statistics relinquished in the summer of 2013 by the u.s. census bureau designated that about three-quarters of the people with a bachelor’s degree in stem fields are not working in those vocations. many non-stem employers are poaching stem-qualified job candidates because they are more ingenious and collaborative than their non-stem counterparts.

as the ecumenical economy perpetuates to evolve, the desideratum for stem-capable workers will perpetuate to grow. by getting edifiers and students involved in the stem kineticism, an incipient generation of adroit workers will be poised to energize and expand this exhilarating field.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
