The atomic number of an atom that has six protons, six neutrons, and six electrons is 6. And the element is carbon.
Carbon is known as a tetravalent compound.
It has four electrons in its outermost shell. It forms a covalent bond with other compounds.
The number of neutrons. = 6
Number of electrons = 6
Number of protons = 6
So the atomic number of the compound is,
The atomic number of an element = Number of protons present in its nucleus
The number of protons given in the compound is 6.
So the atomic number of the compound is also 6.
Carbon has six atomic numbers.
Therefore, the atomic number of an atom that has six protons, six neutrons, and six electrons is 6. And the element is carbon.

Atomic mass iron ( Fe ) = 55.84 a.m.u
55.84 g ------------ 6.02x10²³ atoms
24.0 g ------------- ??
24.0 x ( 6.02x10²³) / 55.84
=> 2.58x10²³ atoms
The elements in<span> groups 1a through 7a are called d. representative elements. The periodic table is organized according to increasing order of the atomic number of the elements. Groups have similar properties while the period of the elements determines the valence electrons in the outer shells.</span>
Answer:
pH = -log₁₀ [H⁺]
Explanation:
pH is a value in chemistry used in to measure solution trying to determine each quality, purity, risks for health of some products, etc.
As you write in the question, [H⁺] = 10^(-pH)
Using logarithm law (log (m^(p) = p log(m):
log₁₀ [H⁺] = -pH
And
<h3>pH = -log₁₀ [H⁺]</h3>
