What is the number of neutrons for Li?
Subtract number of protons (=atomic number) 3 from the total number of protons AND neutrons ( p+n = mass number) 7, leaves the number of neutrons 47-3=4
Most stable types of nuclei have an number of protons and an number of neutrons?
4 protons and 4 neutrons
Neutral atom with 53 protons in its nucleus would have how many electrons orbiting the nucleus?
For a standard atom, the number of protons, electrons, and neutrons is the same. For example: 2 Protons - 2 Neutrons - 2 Electrons Helium 3 Protons - 3 Neutrons - 3 Electrons Lithium 4 Protons - 4 Neutrons - 4 Electrons Beryllium So... 53 Protons - 53 Neutrons - 53 Electrons Iodine
What is the mass number of a helium atom that has 2 protons and 2 neutrons?
Number of neutrons = Mass number - Number of protons = 4 - 2 = 2 neutrons
What is a metal with unequal protons and neutrons?
Lithium: It has 4 neutrons and 3 protons.
What is the number of neutrons for Li?
Subtract number of protons (=atomic number) 3 from the total number of protons AND neutrons ( p+n = mass number) 7, leaves the number of neutrons 47-3=4
How many subatomic particles are in lithium?
6Li has 3 protons, neutrons and electrons. 7Li has 3 protons, 4 neutrons and 3 electrons.
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
How many protons neutrons and electrons does Li have?
The most frequent isotope of lithium has 4 neutrons.
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.
How many 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 is the total number of neutrons in an atom of 7 lithium 3?
The atomic number of lithium is 3, which means that there are three protons. The number of neutrons depends on the mass number of the particular lithium isotope. Mass number is the SUM of the protons and neutrons. An atomic number of 3 and a mass number of 7 means that there are three protons and four neutrons. Lithium has two stable isotopes, Li-6 and Li-7 which means that there are 3 or 4 neutrons, respectively. The atomic number of lithium is 3, which means that there are three protons. The number of neutrons depends on the mass number of the particular lithium isotope. Mass number is the SUM of the protons and neutrons. An atomic number of 3 and a mass number of 7 means that there are three protons and four neutrons. Lithium has two stable isotopes, Li-6 and Li-7 which means that there are 3 or 4 neutrons, respectively.
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.
Most stable types of nuclei have an number of protons and an number of neutrons?
4 protons and 4 neutrons
What is the mass number if an atom has 3 protons and 4 neutrons?
seven
What is the the stability of an isotope based on Its 1. number of neutrons only 2. number of protons only 3. ratio of neutrons to protons 4. ratio of electrons to protons?
It is the ratio of neutrons to protons that generally determines the stability of an isotope.
Neutral atom with 53 protons in its nucleus would have how many electrons orbiting the nucleus?
For a standard atom, the number of protons, electrons, and neutrons is the same. For example: 2 Protons - 2 Neutrons - 2 Electrons Helium 3 Protons - 3 Neutrons - 3 Electrons Lithium 4 Protons - 4 Neutrons - 4 Electrons Beryllium So... 53 Protons - 53 Neutrons - 53 Electrons Iodine
