Neutral atom with 30 protons and 34 neutrons what is atomic number?
30 protons defines the atomic number. It matters not how many neutrons there are. The atomic number is 30, and the element is Zn (zinc).
What is the protons neutrons and electrons for 65Zn?
Protons- 30 Electrons- 30 Neutrons- 35 Zn-65 means the atomic number plus the number of neutrons equals 65. Zinc always has 30 protons; therefore, it's atomic number is 30 and it has 30 protons and electrons. The remaining number is the neutrons: 65-30= 35
If you were able to chemically analyze your stomach fluids 30 minutes after taking two anti acid tablets what would you find?
More hydrogen ions.
Which element has 30 protons?
30 protons means element 30 from the periodic table, which is Zinc. Although it usually doesn't have 30 neutrons, and I doubt that would be a stable isotope. Stable zinc isotopes have 34 and 36 neutrons.
How do you work out 30 percent of a number?
To calculate 30 percent of a number, multiply the number by 0.3. For example, 30 percent of 80 is equal to 80 x 0.3 = 24.
How do you find 30 percent of a number?
To find 30 percent of a number, multiply that number by 0.30 For mental arithmetic it is sometimes easier to divide the number by 100 (to calculate 1%) then multiplying by 30 (for 30%). Simply put move the decimal point of the required percentage two spaces to the right ( to get 1%) and multiply the amount of 1% by the percent wanted. For example: 43 % of 3300 = 0.43 x 3300 = 1419 30 % of 450 = 0.3 x 450 = 135
What is your percent if you miss 6 questions and there are 30 questions total?
To calculate your percentage, first subtract the number missed from the total; In this case, 30-6. Then from there you would take the answer (24) and divide it by the total number of questions (30). Then multiply your answer by 100. .80 * 100 = 80%
If krypton is 30.00 how many grams are their?
If the molecular weight is 30 grams/mole, you need to know the number of moles to calculate the weight. If you have 1 mole, this will yield 30 grams of krypton.
30 minutes to 3 seconds is how many percent decrease?
30 minutes = 30 x 60 seconds = 1800 seconds to calculate the decrease from 1800 to 3 seconds we calculate the difference and then divide through by the start number so the difference is 1800- 3= 1797 and the original start number was 1800 so the decreae in percentage is 1797/1800 x 100% = 99.83 % decrease
What grade is 6 out of 30?
6 of 30 is 20%, so a 20. In letter terms, it means you failed. To calculate this on future exams, simply divide the number of correct answers by the total number of questions on the exam. On this one for example, divide 6 by 30, which is how you arrive at the answer, which is a score of 20.
How many neutrons are there in an element having a mass number of 52 and an atomic number of 22?
30. The Atomic mass is essentially the protons + neutrons. The Atomic number is the protons. Or the neutrons. Or even the electrons. With the exception of ions and isotopes, those numbers are all the same.
How do you find 30 is what percent 20?
You calculate 100*(30/20)
What is the least common multiple of 5 14 and 30?
