As you move down group one of the periodic table, what happens to the atomic radii? They increase, because of the higher number

of occupied energy levels. They increase, because of the stronger attraction between electrons and the nucleus. They decrease, because of the weaker effective nuclear charge. They decrease, because of the lower number of protons.

The correct answer is the atomic radius increase because of the higher number of occupied energy levels.  

Atomic radius increases when going down a group. The valence electrons hold the higher levels because of the enhancing quantum number (n). As a consequence, the valence electrons get further away from the nucleus with the increase in n. The electron shielding inhibits these outer electrons from getting fascinated towards the nucleus. Therefore, they are held, and the resulting atomic radius is greater.

Convert 533 cm/s to units of meters per minute. Show the unit analysis by dragging the conversion factors into the unit‑factor s
lukranit [14]

Answer:

319.8 m/min

Explanation:

533 cm/s

We can convert 533 cm/s to m/min by doing the following:

First, we shall convert 533 cm/s to m/s. This can be obtained as illustrated below:

Recall:

100 cm/s = 1 m/s

Therefore,

533 cm/s = 533 cm/s /100 cm/s × 1 m/s

533 cm/s = 5.33 m/s

Finally, we shall convert 5.33 m/s to m/min. This can be obtained as follow:

1 m/s = 60 m/min

Therefore,

5.33 m/s = 5.33 m/s / 1 m/s × 60 m/min

5.33 m/s = 319.8 m/min

Therefore, 533 cm/s is equivalent to 319.8 m/min

What happens when chlorine forms an ion?
zmey [24]

The chlorine usually forms a Chloride ion.

The Chlorine gains an electron leaving it 17 protons and 18 electrons. Since it has 1 more electron than protons, chlorine has a charge of −1, making it a negative ion. When ions form, atoms gain or lose electrons until their outer energy level is full.

What do you mean by Chlorine forming an ion?

Chlorine has one electron when it forms an ion to be an anion with a charge of -1. The charge of an ion, and thus the number of electrons the atom will gain or lose. If an atom has less than four valence electrons, it will lose them to become a cation.

The chloride ion is the anion  Cl− which is formed facilitating important chemical reactions coupled with its usage in the everyday world.

C + O2 → CO2 ,
DerKrebs [107]
First, if you want to get the amount of production from the equation, you need to use the units of mol. So, we need to know the molar mass of C which is 15.75/12=1.31 mol. Then we need to use the less part(O2) to get the production amount which is 0.116 mol. Then we can get the answer in units of g: 0.116*(12+16*2)=5.104 g.
