How many protons are in a lithium nucleus?
The atomic number of lithium is 3. Therefor there are 3 protons and neutron in the nucleus of lithium. Lithium also has 4 neutrons. atomic # = protons and neutrons neutrons = rounded atomic mass - atomic number Sources- 7th grade Acc. Science
What number of protons in lithium?
Lithium has the atomic number of 3, which means it has 3 protons, and a neutral atom of lithium has 3 electrons.
What is the number of an atom with 3 protons 4 neutrons and 3 electrons?
The number of protons in the nucleus is given by the atomic number. So in your example, this would be atomic number 3 (lithium). It will have atomic mass of 7 (3 protons + 4 neutrons), and a charge of 0 since there are also 3 electrons to balance the 3 protons.
How can the number of protons electrons and neutrons can be calculated when given atomic number and atomic mass?
For a given atomic number. Then that neutrally charged element has the same number of protons and electrons. e.g. Carbon ; Atomic Number 6, has 6 protons and 6 electrons. For a given atomic MASS , the the number of neutrons can be found, by subtracting the mass from the atomic no. e.g. Carbon ; Atomic Mass 12, has 12 - 6 = 6 neutrons. Most elements can exhibit different atomic masses , known as ISOTOPES. , This is when the given element has a different number of neutrons. e.g. Carbon ; atomic mass 13 , has 13 - 6 = 7 neutrons , described as Carbon -13 or C-13 Similarly Carbon again ; atomic mass 14, has 14 - 6 = 8 neutrons, described as Carbon-14 or C-14. A further example is hydrogen. It exhibits three isotopes. protium ; 1 proton, 0 neutrons and 1 electron Mass = 1 (H-1 or H) deuterium ; 1 proton, 1 neutron and 1 electron Mass = 2 (H-2 or D) tritium ; 1 proton 2 neutrons and 1 electrons. Mass = 3 (H-3 or T) Notice in all three isotopes the number of protons remains the same, so it is still the same element. Carbon
How many protons neutrons and electrons are in aluminum?
,Aluminium ; from the Periodic Table its atomic no. is 13. Its atomic mass is 27. From the information we can deduce ;- #1 ; The number of protons is '13' #2 ; the number of electrons is '13' #3 ; the number of neutrons is '27-13 = 14'. Remember for all elements, the number of protons and electrons is the same as the atomic number ; its position in the periodic table. Remember to, for all elements, if you subtract the atomic mass from the atomic number , then answer id the number of neutrons in the most common isotope.

What is is the formula for the atomic theory for 13 protons 10 electrons and 14 neutrons?
Al 3+
What number of protons in lithium?
Lithium has the atomic number of 3, which means it has 3 protons, and a neutral atom of lithium has 3 electrons.
How many protons does linthium have?
An atom's atomic number tells us its number of protons. Lithium's atomic number is 3. Thus lithium has 3 protons per atom.
What is the number of an atom with 3 protons 4 neutrons and 3 electrons?
The number of protons in the nucleus is given by the atomic number. So in your example, this would be atomic number 3 (lithium). It will have atomic mass of 7 (3 protons + 4 neutrons), and a charge of 0 since there are also 3 electrons to balance the 3 protons.
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 is lithiums atomic number?
lithium s atomic no is 3 it has 3 protons and 3 electrons
How many protons and electrons does Li 1 have?
li has atomic no. 3 so it has protons= 3 electrons- 3
Is neon lithium?
No. Lithium is an element with atomic number 3 (or 3 protons) and neon is an element with atomic number 10 (or 10 protons). Both are not same.
Is mass number the same as atomic number?
No. Atomic number refers to the number of protons present in the nucleus of the atom whereas mass number refers to the sum of the number of protons and neutrons in the nucleus. For example, the isotope lithium-6 has an atomic number of 3 (for 3 protons) and a mass number of 6 (for 3 protons and 3 neutrons).
What 3 atomic anions have 7 protons?
Bruh
