Sonya is studying a nonmetal element. She learns that the element is like other elements in its group because it can bond to form a salt or an acid. She also learns that the element is the most reactive element in its group. Which element is Sonya most likely studying?
Answers
Answer is: fluorine (F).
Group 17 (halogens) elements: fluorine (F), chlorine (Cl), bromine (Br) and iodine (I). They are very reactive and easily form many compounds.
Halogens need to gain one electron to have electron cofiguration like next to it noble gas.
Fluorine has atomic number 9, it means it has 9 protons and 9 electrons.
Fluorine tends to have eight electrons in outer shell like neon (noble gas) and gains one electron in chemical reaction. Fluorine is most reactive nonmetal.
Electron configuration of fluorine: ₉F 1s² 2s² 2p⁵.
Electron configuration of neon: ₁₀Ne 1s² 2s² 2p⁶.

Answer;
= 48,828.125 mi/hr²
Explanation and solution;
- Centripetal acceleration is the rate of change of angular velocity. Centripetal acceleration occurs towards the center of the circular path along the radius of the circular path.
- Centripetal acceleration is given by; V²/r ;
V = 125 mi/h and r = 0.320 miles
- Thus; centripetal acceleration = 125²/0.320
=15625/0.320
= 48,828.125 mi/hr²

A chain reaction is a nuclear reaction that occurs when sufficient unstable nuclei are present so that when one splits (decays), its products hit other unstable nuclei, causing them to decay and initiating a chain reaction.
If this reaction goes uncontrolled, a massive explosion occurs. Such a reaction is the type that went uncontrolled when nuclear bombs were dropped over Hiroshima and Nagasaki in World War II. A chain reaction is much like dominoes all in a row; when one goes down, they all go down in order. The only way to block the chain reaction is to pull out a domino or to block the fall so the "chain" is broken.
The amount of fissionable material needed to accomplish a spontaneous chain reaction is called the critical mass. The critical mass for U-235 is about 1 kg. This explosive fission process takes place quickly, and an incredible amount of energy is released when it occurs.

oxygen
the answer is going to be oxygen. This is because on the periodic table, sulfur and oxygen are in the same group or "family" in the periodic table of elements.

Answer:
The correc answer is C. greenhouse gases.
Explanation:
The atmosphere is a layer of gases that surrounds our planet and is one of the essential elements for life on it.
The atmosphere protects us from harmful solar radiation from the Sun. The Sun, in addition to light and heat (infrared radiation), emits other radiation such as gamma rays, X-rays and ultraviolet rays that are harmful to life. These harmful radiations are absorbed by the atmosphere.
The atmosphere also protects us from the impacts of meteorites. These are from outer space are attracted by gravity and fall on the earth's surface. Upon coming into contact with the gases of the atmosphere, at high speed, the friction causes them to heat up so much that they become incandescent and end up disintegrating, avoiding reaching the ground. Only the largest (rare) can pass through the atmosphere and reach the ground.
Something similar happens that with meteorites occurs with the dangerous particles of space.
Greenhouse gases contribute, to a greater or lesser extent, to the increase of the greenhouse effect, since they are capable of absorbing the heat energy carried by long-wave radiations that are reflected by the Earth's surface.This phenomenon prevents the solar energy constantly received by the Earth from returning immediately to space and causing the temperature of the air near the ground to rise. Then there are changes in the climate such as sea level rise, changes in rainfall, disappearance of forests, extinction of organisms and problems for agriculture.
So the correc answer is C. greenhouse gases.
