What is atomic radius?

2 answers:

7 0

The chemical element's atomic radius is measured by the size of its atoms, usually the medium or typical distance between the central nucleus and the surrounding electron shells. As the limit is not a well defined physical entity, different definitions of non-equivalent atomic radius exist.

Hope this helps!

What is the number of the group that has the most reactive nonmetals (give number and letter- Ex 1A, 2A, etc.)?

Kryger [21]

Answer:

Group 7A

Explanation:

The group 7A elements consists of the most reactive non-metals on the periodic table.

This group is known as the group of halogens. They consist of element fluorine, chlorine, bromine, iodine and astatine.

The elements in this group have the highest electronegativity values.
They have 7 valence electrons and requires just one electron to complete their octets.
This way, they are highly reactive in their search for that single electron.

Which of the following conditions would lead to a small population size? a. a low birth to death ratio b. a high birth to death

Vinil7 [7]

Answer:

Choice A.

A low birth to death ratio

Explanation:

A low birth to death ratio means that people are dying faster than they are being born. This leads to a decreasing population size.

40o+2 protons electrons And neurons

KatRina [158]

Answer: There are few simple rules to follow.

(1) The atomic number is equal to the number of protons.

= number of protons

(2) In neutrally charged elements, the number of electrons is the same as the number of protons.

= number of protons = number of electrons (no charge)

Otherwise, positive charge means that the element lost an electron and negative charge means it gained an electron.

(3) The atomic mass is equal to the sum of the number of protons and number of neutrons.

= number of protons + number neutrons

+ number neutrons

So if you say that

= 20 and

= 40, then

+ number neutrons

40 = 20 + number of neutrons

40 - 20 = number of neutrons

Therefore,

number of neutrons = 20
