The noble gas, Helium has only two electrons with the electronic configuration as 1s2. Hence, it does not have a complete octet. and thus, it doesn't follow the octet rule.

An octet is a set of eight. Atoms of each of the noble gases (except helium) have eight electrons in their highest occupied energy levels and the general electron configuration of ns2np6.

1. not affected by a magnet                      1 liquid

2. mostly space                                          2 solid

3. flows freely but particles still attract 3 proton

5. free to move in all space                       5 alpha particles

6. negatively charged particles                 6 atoms

7. atoms nearly fixed in space                   7 gamma ray                                                    8. helium nucleus                                        8 electron (beta)

The AZX symbol of  a cation with 13 neutrons is A = 24 , Z = 11 and X = Na+

AZX is a symbol which stands for;

Note, cations are positively-charged ions having more protons than electrons due to loss of one or more electrons.

Sodium ion represented as Na+ is a cation which lost one electron. It has 13 neutrons and 11 protons.

But the mass number of an element, A is the sum of protons and neutrons of the element.

Thus, for Na+

A = 13 + 11 = 24

Z = 11

X = Na+

Therefore, the AZX symbol of  a cation with 13 neutrons is A = 24 , Z = 11 and X = Na+

Explanation:

All types of energy can be resumed into two basic types of energy which include kinetic energy and potential energy.

Energy is the ability to perform a given work. Kinetic energy is energy in movement, whereas potential energy is stored energy.

For example, plant photosynthesis makes reference to chemical energy (potential energy), popcorn makes reference to thermal energy, etc.

In conclusion, all types of energy can be resumed into two basic types of energy which include kinetic energy and potential energy.

I highly suggest you watch OChem Tutor's videos on IUPAC nomenclature because the actual naming would take a lot of time to teach in text-based format. But here is how to name them:

1) I think there are two seperate pictures for number 1. The molecule on the left is 1-pentene and the one on the right is 4-methyl-1-pentene. If the whole thing is one molecule but there is just a bond missing where the red marker numbers are, that molecule would be 9-methyl-1,6-decadiene.

2) 4-methyl-2-pentene

3) 2,4-octadiene

4) 1,5-nonadiene

More positive ions shows acidic whereas more negative ions indicates basic solution.

That side which has more positive charges is considered as acidic solution while on the other hand, that region where negative charges are present in large number as compared to positive charges is considered as basic or alkaline solution.

So we can conclude that more positive ions shows acidic whereas more negative ions indicates basic solution.

2) In contrast, milk, hydrochloric acid (hydrogen chloride gas dissolved in water), brick and air cannot be called pure substances because they consists of particles of more than one kind of matter.

The alkali metals can't exist alone in nature because of incomplete outermost shell of alkali metals.

The alkali metals have the high thermal and electrical conductivity. It has high lustre, ductility, and malleability as compared to other materials. Each alkali metal atom has one electron in its outermost shell which make more reactive.

Answer:

3.1 x 10^10

Explanation:

there are 9 zeroes, so the quick way is too just add a one to the 9 and you get 10, so that is your power.

Taking into account the scientific notation, the result of the sum is 6.6365×10⁵.

First, remember that scientific notation is a quick way to represent a number using powers of base ten.

The numbers are written as a product:

a×10ⁿ

where:

You want to add two numbers in scientific notation. It should be noted that when the numbers to be added do not have the same base 10 exponent, the base 10 power with the highest exponent must be found.

In this case, the highest exponent is 5.

Then all the values ​​are expressed as a function of the base 10 exponent with the highest exponent. In this case: 8.6500×10³= 0.086500×10⁵

Taking the quantities to the same exponent, all you have to do is add what was previously called the number "a". In this case:

0.086500×10⁵ + 6.5500×10⁵= (0.086500+ 6.5500)×10⁵=  6.6365×10⁵

Finally, the result of the sum is 6.6365×10⁵.

The correct answers are Potential and Kinetic energy.

An object can store energy as a result of its position. For example, the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy. Similarly, a drawn bow is able to store energy as a result of its position.

Kinetic energy is a form of energy that an object or a particle has by reason of its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy.
