Number of protons in an atom is called?
The number of protons in an atom is the atomic number. It tells you which element the atom is.
What does atomic number represent?
It is the number of protons in the nucleus of the atom and it determinnes many properties of the atom. The atomic number is also the number of electrons and is a constant for every element
What is the number of protons in a atom of an element?
The number of protons in an element is equal to the atomic number. (dont mix this up with atomic mass. It is simply the large number that appears usually in the top left hand corner on the periodic table. For example, Lithium has 3 protons. Sulfur has 16 protons and so forth)
What the atomic number tell us?
The atomic number of an atom is the number of protons in the nucleus of an atom. The number of protons determines the identity of an element and its properties. Hope this helps :3
What is number of positively charged protons in an atom's nucleus is the?
the number of protons in a single atom depends on the element. for example, hydrogen would have 1, helium would have 2, beryllium would have 3, and so on. the number of protons in a single atom depends on the element. for example, hydrogen would have 1, helium would have 2, beryllium would have 3, and so on.
How many protons are there in an atom the element lithium if it has an atomic number of 3?
Lithium has 3 protons. The atomic number and the number of protons will be the same.
What is the atomic number for the elements?
The atomic number of an element represents the number of protons found in the nucleus of an atom of that element. It is unique to each element and is used to identify and classify elements on the periodic table.
Distinguish between atomic number and atomic mass?
The Atomic Number of an element is equal to the number of Protons/Electrons in the nucleus and the Atomic Weight is approximately the total number of Protons/Electrons and Neutrons combined. Using Carbon as an example: Total Protons/Electrons = 6, therefore the Atomic Number is 6 Total Neutrons = 6, and the Atomic Weight is 12 Question? The Atomic Number of Lithium = 3 The Atomic Weight of Lithium = 7 How many Protons/Electrons? How many Neutrons? Answer: Protons/Electrons = 3 Neutrons = 4
What atom or isotope of an element has an atomic mass of 26 charge of 3 13 protons 13 neutrons and 10 electrons?
The number of protons identifies this element as aluminum, which has an atomic number of 13. The number of protons is an element's atomic number on the periodic table. Every element has its own unique atomic number which defines it as that element.
What is the atomic number and the mass number of an element with 20 atomic number and 23 mass number?
The element with atomic number 20 is calcium. The mass number 23 indicates the total number of protons and neutrons in the nucleus of the atom. Since the mass number is 23 and the atomic number is 20, the number of neutrons in this calcium atom would be 3 (23 - 20).
Number of protons in an atom of an element?
Whatever the number of neutrons are in the nucleus is the number of protons. Ex: Neutrons- 4 Protons - 4 Electrons-3 (Which would be an example of a positively charged atom)
What two pieces of information does the atomic number give?
The atomic number gives you the number of electrons and protons there are in an atom. ex: Carbon (C) has atomic number 6. So we know that it has 6 protons and 6 electrons
