Which atom has 3 protons 3 neutrons and 3 electrons?
lithium atom
A lithium atom contains 3 protons in its nucleus irrespective of the number of neutrons or electrons. a. b. Notice that because the lithium atom always has 3 protons, the atomic number for lithium is always 3.
How many electrons are there in an atom with three protons?
For example, a lithium atom (Z=3, A=7 amu) contains three protons (found from Z), three electrons (as the number of protons is equal to the number of electrons in an atom), and four neutrons (7 – 3 = 4).
What is the number of electrons in an atom that has 3 protons and 4 neutrons?
For example, a lithium atom (Z=3, A=7 amu) contains three protons (found from Z), three electrons (as the number of protons is equal to the number of electrons in an atom), and four neutrons (7 – 3 = 4). “atomic number.”
What isotope has 3 protons and 3 electrons?
Lithium-7. Lithium-7 is by far the most abundant isotope of lithium, making up between 92.2\% and 98.1\% of all terrestrial lithium. A lithium-7 atom contains three protons, four neutrons, and three electrons.
What element has 3 protons 3 electrons and 6 neutrons?

| 73Li | 3 | |
| beryllium | 94Be | 4 |
What is the mass number of an atom with 3 protons and 4 neutrons and 3 electrons?
Lithium, for example has three protons and four neutrons, leaving it with a mass number of 7.

What are the 3 particles that make up the atom?
Given that these particles make up atoms, they are often referred to as subatomic particles. There are three subatomic particles: protons, neutrons and electrons.
What element has 3 protons 2 electrons and 3 neutrons?
What is the atomic number for an element with 3 protons?
Lithium is the element that is atomic number 3 on the periodic table. These means each atom contains 3 protons. Lithium is a soft, silvery, light alkali metal denoted with the symbol Li.
What is the mass number of an atom with 3 protons 4 neutrons and 3 electrons?
Do electrons and protons have the same number of protons?
No matter how many electrons or neutrons an atom has, the element is defined by its number of protons. In fact, it’s actually possible to have an atom consisting of only a proton (ionized hydrogen). For a neutral atom, the number of electrons is the same as the number of protons.
What is a neutral atom with the same number of protons?
A neutral atom has the same number of protons and electrons (charges cancel each other out). An ion has an unequal number of protons and electrons. If the charge is positive, there are more protons than electrons. If the charge is negative, electrons are in excess.
How many protons does lithium (Li) have?
The number of protons an atom has is equal to its atomic number. In this case, there are 3 protons, so its atomic number is 3 and this is lithium (Li), the third element on the Periodic Table. Atomic Massis sum of the number of protons and neutrons in the nucleus. Here, that is 3 and 4, respectively, giving our atom an atomic mass of 7.
What determines the number of protons found in an element?
Each element is defined by the number of protons found in each of its atoms. No matter how many electrons or neutrons an atom has, the element is defined by its number of protons.
