90 points urgent need answers correct and quick 1. oxygen is more reactive than nitrogen. true false match the element with its description. match term definition potassium great conductor of heat and electricity barium has properties of both metals and nonmetals boron nonreactive gas neon malleable and highly reactive 3. which of the following elements is the most reactive? beryllium calcium magnesium barium a neutral atom of chlorine (cl) has an average mass of 35 amu and 17 electrons. how many neutrons does it have? 17 35 18 52 which of the following elements has the largest atomic radius? potassium calcium cobalt nickel the element manganese is represented by the symbol (capitalization is important.) answer for blank 1: mn? use your periodic table of elements. take any element of your choosing (from period 4 or above) and answer the following questions: what is the element's name and symbol? is it a metal, nonmetal, or metalloid? which family does it belong to? how many protons, neutrons, and electrons does its neutral atom have?

1) True
Oxegen is more reactive to than nitrogen

2) I'm sorry, I don't know

3) Barium
It's more reactive than all the other elements

Last Question to the list:
The element I chose is sodium which contains 12 neutrons, 11 electrons and 11 protons. The number of electrons and protons come from the element's atomic number, which is 11. Sodium belongs to the Alkia Family which and has a atomic mass of 22.98977.

I am doing the same thing right now lol I got 100 percent. Here are my answers:

1. True

2. Potassium - Malleable and highly reactive

Barium - Nonreactive gas

Boron - Has properties of both metal and nonmetal

Neon - Great conductor of heat and electricity

3. Magnesium

4. Cobalt 

5. Arsenic As Metalloid Nitrogen, group 15, period 4 33 protons 33 neutrons 
All are correct I got 100 percent with these answers. Hope it helps! :)

The answer to your question really depends on three things: how much water you have, how cold it is to start out, and how cold the things around it are. water actually freezes when it gets to 32 degrees fahrenheit (0 degrees celsius), but the time it takes to get there may be different.  let's start with the first. if you take two glasses, and fill one with a tiny bit of water, and the other about halfway, then put them both in the freezer, the one with less water will freeze first (you can try this at home, but i recommend using plastic cups and not glass ones).  now let's move on to the second part. let's say you have two glasses, and you fill one with really cold water that has been in the refrigerator, and the other with really hot water from the sink. if you put both of them in the freezer, the one that started out colder will freeze first.  for the third part, let's imagine that you have two glasses with the same amount of water in them, and the water is at the same temperature. imagine putting one outside on a really really cold day in georgia, and having a friend in alaska put one outside on the same day. since it would be so much colder in alaska, the glass of water there would freeze before yours.  so, if you took a tiny bit of really cold water in a glass, and put it outside on a cold day in alaska, it would freeze a lot faster than a big glass of hot water outside on a cold day in georgia. 

Answerd. may include all of these are many definitions of bases: the  brønsted-lowry definition of acids and bases says that bases are proton acceptors.the arrhenius definition of acids and bases says that bases increase [oh⁻] in solution (thereby producing oh⁻ ions)the lewis definition of acids and bases says that bases donate electron pairs.therefore, the sensible answer is that a base may include all of the described characteristics.
