I am a metalloid. I am in the nitrogen family and row 4. I have an atomic mass of 74.92. I can be used as a poison. Who am I?

Answers

Arsenic

Arsenic has an atomic mass of 74.92, is a well known poison, and a metalloid.

Answer:

As – Arsenic

Explanation:

Let's break this down step by step. Make sure you have a periodic table to reference.

"I am a metalloid" – We will be looking towards the right side of the periodic table. The possible choices are boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), and astatine (At).

"I am in the nitrogen family" – Families are elements grouped by columns. The nitrogen family is group 15. The possible choices are now arsenic (As) and antimony (Sb).

"and row 4" – Counting from the very top (don't forget row 1 of hydrogen and helium), we can see that arsenic (As) is in the 4th row.

"I have an atomic mass of 74.92" – Arsenic (As) does have an atomic mass of 74.92, which confirms our answer.

Hope this helps!

How do valence electrons in an atom affects the chemical reaction?

Answers

The number of electrons in an atom's outermost valence shell governs its bonding behaviour.

The number of electrons in an atoms outermost valence shell governs its bonding behaviour.
Elements whose atoms have the same number of valence electrons are grouped together in the Periodic Table. Generally, elements in Groups 1, 2, and 13 to 17 tend to react to form a closed shell with the electron configuration s²p⁶.

2. Make a 29 day timeline. Along the timeline draw and label the phases of the Moon starting with a full moon, crescent, first quarter, gibbous and full. Finish the second half showing the waning moons back to the new moon.

Answers

Dont know if this helps but here

Moon phases represent the names given to points in its orbit around Earth. Each phase lasts for only an instant as the moon constantly moves. To the naked eye, the full moon lasts about three days, but in reality, it is a full moon for just an instant before it begins to wane. The moon takes just under one month -- an average of 29 1/2 days -- to complete its phases.

TL;DR (Too Long; Didn't Read)

As the moon passes gradually and continually through its monthly cycle, each phase lasts only an instant. The Full Moon, for example, is simply a point halfway between waxing gibbous and waning gibbous.

Phases of the Moon

The moon has eight phases: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter and waning crescent. But it is not as simple as dividing 29 1/2 by eight to find out how long each phase lasts. The fraction by which the moon is illuminated steadily increases or decreases at all times.

Primary and Intermediate Phases

The primary phases of the Moon cycle are the new moon, the first quarter, the full moon and the last quarter. The dates and times of these phrases -- which you can calculate or find on calendars -- change from month to month according to the positions of the Sun and the Moon. Astronomers refer to the crescent and gibbous phases as intermediate phases.

A bank is developing an algorithm that will help them decide who to make loans to. As input the algorithm will consider information about the person applying for the loan and the amount of money requested, and as output the algorithm will decide whether the bank should give that loan.The bank intends to develop the algorithm using machine learning techniques. The algorithm will be trained using data from past loan decisions made by human bankers.Which of the following best describes whether this algorithm will include bias?Group of answer choicesA. While the algorithm may be biased, the eventual decision made the algorithm will not beB. The algorithm will not be biased because using machine learning eliminates human biasesC.
