What atom has 3 electrons 3 protons and 4 neutrons?

lithium atom
A lithium atom contains 3 protons in its nucleus. Notice that because the lithium atom always has 3 protons, the atomic number for lithium is always Z = 3. The mass number, however, is A = 6 for the isotope with 3 neutrons, and A = 7 for the isotope with 4 neutrons. In nature, only certain isotopes exist.

What is the charge on a lithium atom has 3 protons 3 electrons that loses 1 electron?

A lithium atom has 3 protons and 3 electrons. It can lose one of its electrons, making it an ion. It now has more positive protons than electrons so it has an overall positive charge. Therefore it is a positive ion.

What is the charge of 3 protons?

-2
3 protons, 3 neutrons, 2 electrons Charge -2, 8 neutrons, mass number 17.

What would the overall charge of an atom be if there are 3 more electrons than protons?

A proton and an electron have an equal amount but an opposite type of charge. Thus, if an atom contains equal numbers of protons and electrons, the atom is described as being electrically neutral. Conversely, any particle that contains more electrons than protons is said to be negatively charged.

What atom has 3 protons 3 neutrons 3 electrons?

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.

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.

Why is lithium atomic number 3?

Lithium is an alkali metal with the atomic number = 3 and an atomic mass of 6.941 g/mol. This means that lithium has 3 protons, 3 electrons and 4 neutrons (6.941 – 3 = ~4).

What is the charge of an atom that loses 3 electrons?

When it becomes an ion, it loses 3 electrons, leaving behind only 10. Now the charge is +13 + (−10) = +3. Thus the remaining aluminum ion is said to have a net positive charge of 3, represented as +3 or 3+.

What atom has 4 protons 4 neutrons and 4 electrons?

beryllium
The element with atomic number 4 is beryllium, which means each atom of beryllium has 4 protons. A stable atom would have 4 neutrons and 4 electrons.

What atom has 3 protons 3 neutrons and 3 electrons?

What is the charge of 3 electrons?

Electron Charge to Coulomb Conversion Table

What is the charge of the atom when 3 electrons are lost?

These lose electrons to gain a charge of +1 or +2, and group 13 elements have three electrons in their outer shell and form ions with a +3 charge.

What is the charge of an atom with 3 protons and electrons?

Protons have charge 1+ , electrons 1- and neutrons no charge. An atom with 3 electrons and 3 protons will not have a charge. But if it loses one electron then that means it has now 3 positive charges/protons and 2 negative charges/electrons.

How many protons neutrons and electrons are in a neutral atom?

Therefore, the mass number of an atom with 3 protons, 4 neutrons, and 3 electrons is 7. How many electrons are in a neutral atom that has 3 protons? Atoms are neutral in electrical charge because they have the same number of negative electrons as positive protons (Table 4.5. 1)….Atomic Number.

What happens when there are more protons than electrons?

If there are more electrons than protons, the atom will be negatively charged (5 electrons and 3 protons –> charge = -2), and if there are more protons than electrons, the atom will be positively charged (2 electrons and 3 protons –> charge = +1). Home Science Math and Arithmetic

Does lithium have 3 protons 3 electrons and 3 neutrons?

Yes, nuclei of lithium atoms all have 3 protons, that’s what qualifies them to be called lithium atoms. Such atoms belong to the element lithium. However, they can have any numbers of neutrons and still be called lithium atoms. What element has 3 protons 3 electrons and 4 neutrons?
