Answer: If element Q has 11 protons, its atomic <u>number</u> is 11.
Step-by-step explanation:
The atomic number of a chemical element is the total number of protons that each atom of that element has.
In other words: it indicates the amount of protons that is present in the nucleus of an atom.
In this sense, the periodic table of the elements arranges the chemical elements in the form of a table, ordered by their atomic number (number of protons), by their configuration of electrons and their chemical properties.

Okay so you have to do
138 times .40-move the decimal over 2 times
that is 55.2 so 40 percent of 138 is 55.2 so add that on to 138 to get 192 students at the school. There you go :)
Integers are whole numbers that can range from negative infinity to positive infinity. Irrational numbers are numbers with repeating ends and have decimals. Rational numbers on the other hand can be positive or negative which can be expressed as fractions. natural numbers are positive integers only. hence, -14/11 is a D. rational number
