Multiply the number by 1/5 or 0.2
Neutrons do not have an electrical charge; they are neutral particles found in the nucleus of an atom. Therefore, the number of neutrons does not directly determine the number of electrons. In a neutral atom, the number of electrons equals the number of protons. If you have 5 neutrons, you cannot determine the number of electrons without knowing the element, as the number of protons (and thus electrons) will vary depending on the specific isotope.
You can determine if a plastic item is made of polyethylene or polypropylene by looking for the recycling symbol on the item. Polyethylene is usually labeled with the number 2 inside the recycling symbol, while polypropylene is labeled with the number 5.
If you have both the mass number and atomic number you can figure it out, since the atomic number is the number of protons. Say the mass number is 13 and the atomic number is 8. 13-8 is 5, so you would have 5 neutrons.
the atomic number is determined by the number of protons in a nucleus.
Count the number of species, and determine their relative abundance.////Apex
If a number is a multiple of 5, it will be greater than 5 and end in a 5 or a zero.
Since 5 is a prime number, then any number, which is not a multiple of 5, is relatively prime with the number 5. You can determine if a number is a multiple of 5, by looking at the ones place digit. If it is a 0 or 5, and the number itself is not zero, then the number is a multiple of 5.
To find the absolute value of a number count the amount of spaces it is away from Zero. If the number is 5 then the absolute value is 5. If the number is -5 then the absolute value is 5. And so on and so forth.
"one quarter of a number increased by 5" is an expression. It is NOT an equation. There is, therefore, no method that can be used to determine what the number is.
Protons: 5 Neutrons: 7 Electrons: 5
To determine the answer to (-5) × 4, you can visualize it on a number line. Start at 0 and move left, since multiplying by a negative number indicates a direction to the left. For each of the 4 steps, move 5 units left: from 0 to -5, then from -5 to -10, from -10 to -15, and finally from -15 to -20. Thus, (-5) × 4 equals -20.
The group number determines the number of valent electrons. For example, the elements in the group 5 have 5 valent electrons.
It is in the thousands' place.
Any whole number, in order to be divisible by 5, must end in either 0 or 5.
295 is composite - 5 x 59.

10, 25, 50 are the composite factors of the composite number 50. 2 and 5 are prime.
