How do you find number of protons?
The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.
How many protons are in an element?
The number of protons in an atom is equal to the atomic number of the element. For example, let's use oxygen. According to the periodic table, oxygen has the atomic number eight. The atomic number is located above the element's symbol.
What has 16 protons and 18 neutrons?
So, if there are 16 protons, the element must be sulfur. The mass number for this isotope is 34 – there are 16 protons and 18 neutrons.
What has 17 protons and 18 neutrons?
Answer and Explanation: Chlorine-35 has 17 protons and 18 neutrons.
How many atoms are there in calcium?
Explanation: The Periodic Table tells us that 6.022×1023 individual calcium atoms have a mass of 40.1⋅g .
How did you get the number of protons electrons and neutrons?
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

How do you find protons electrons and neutrons?
For example, Consider N(nitrogen) with atomic number 7 and mass number 14. As atomic number represent number of proton or electron, hence, nitrogen contain 7 proton and 7 neutron and Mass number is 14 out of which 7 are proton, so remaining 7 are neutrons.
Are protons and electrons equal?
The number of electrons on a neutral atom is equal to the number of protons in the nucleus of the atom.
How do you find protons?
Locate the element's atomic number. The atomic number is located above the element symbol, in the upper left-hand corner of the square. The atomic number will tell you how many protons make up a single atom of an element. For example, boron (B) has an atomic number of 5, therefore it has 5 protons.
