Which statement describes the number of protons in each atom of an element? (1 point) The number of protons is given by the atomic number, which increases by one moving from
left to right across each row of the periodic table.
The number of protons is given by the mass number, which increases by one moving from left
to right across each row of the periodic table.
The number of protons is given by the atomic number, which increases by one moving down
in its column in the periodic table.
The number of protons is given by the mass number, which increases by one moving down in
its column in the periodic table.

By definition of atomic number, the correct answers are:

You have to know that atoms are made up of a nucleus made up of protons and neutrons, and a shell made up of electrons. Protons are positively charged, while neutrons are electrically neutral (that is, they have zero charge). Therefore the atomic nucleus always has a positive charge. On the other hand, electrons are negatively charged.

The atomic number is the total number of protons that make up the atomic nucleus of a given chemical element and is represented by the letter Z.

An atom is naturally neutral and has the same number of electrons and protons.

The atomic number is used to classify the elements within the periodic table of elements, going from the smallest to the largest number of protons in the nucleus as you progress through the rows and columns of the table. That is, as you travel a period (row) from left to right and as you travel a group (column) from top to bottom, the atomic number increases.

In summary, the correct answers are:

The answer is "The number of protons is given by the atomic number, which increases by one moving from left to right across each row of the periodic table."

Explanation:

If you look at the periodic table, the elements atomic numbers increase from left to right by one. Therefore, the protons also increase by one from left to right because the number of protons in an element is the same as the atomic number.

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
