How do the numbers of metal and non-metal elements compare? Estimate an approximate percentage difference.
Lerok [7]

Answer:

metal to non metal ratio is 97/21 = 4.62 or

82.2% metals, 17.8% non metals

Explanation:

How do the numbers of metal and non-metal elements compare? Estimate an approximate percentage difference. (learning about the periodic table if...

of 118 elements in the periodic table , 21 are non metals (even H has metallic properties when approching 0 degrees K)

this means there ar 21 nonmetals and 118-21=97 metals.

A student observes two strips of magnesium, mg ribbon that are each 3cm long. One strip of magnesium
ankoles [38]

Therefore option c , i.e. The substances in both test tubes are reactive only at high temperatures. is the only statement which is NOT supported by the student's observations.

<h3>What is the reaction between Magnesium and Hydrogen ?</h3>

Magnesium reacts with hydrochloric acid to produce hydrogen gas

Mg (s) + 2 HCl (aq) → MgCl₂ (aq) + H₂ (g)

In this reaction, the magnesium and acid are gradually used up , which can be seen in the test tube 2 .

A chemical reaction is taking place in Test tube 2 ,

Hydrogen gas is released in test tube 2 ,

Energy is released in the reaction involving hydrochloric acid and we can see in test tube 2 the reaction is going on

therefore option C i.e. The substances in both test tubes are reactive only at high temperatures. is the only statement which is NOT supported by the student's observation.

To know more about the chemical reaction between Magnesium and Hydrogen and this test.

The resulting daughter isotope that is formed when the atom astatine-213 undergoes alpha emission is: ​
bagirrra123 [75]
Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay (-decay), beta decay (-decay), and gamma decay (-decay), all of which involve emitting one or more particles or photons. The weak force is the mechanism that is responsible for beta decay, while the other two are governed by the usual electromagnetic and strong forces.[1]
