An element with 120 protons and 2 electrons would belong to Group 2 on the Periodic Table, also known as the alkaline earth metals group. Elements in this group typically have 2 valence electrons and exhibit similar chemical properties due to their electronic configuration. Examples of elements in Group 2 include beryllium, magnesium, calcium, strontium, and barium.
What else can I help you with?
An element has an atomic number of 30 how many protons and electrons are in a neutral atom of the element?
It will have 30 protons and 30 electrons if the atom is neutral.
What element has 51 protons and 52 electrons?
51 protons defines the element as antimony (Sb). It normally has 51 electrons, so with 52 electrons, it would be Sb with a 1- charge.
What group would a element synthesized with 115 protons group?
An element synthesized with 115 protons would belong to Group 15 (or Group 5A) in the periodic table. This group is known as the nitrogen group, consisting of elements such as nitrogen, phosphorus, arsenic, antimony, and bismuth.
Why doesnt the number of protons change for a single element while the neutrons and electrons can?
The number of protons in an atom determines its identity as a specific element. Changing the number of protons would change the element. Neutrons and electrons can be added or removed without changing the identity of the element since they do not affect the element's chemical properties.
What element has 8 proton 8 neutrons and 10 electrons?
The element that has 9 protons is fluorine. Its atomic number is 9, indicating that the element has 9 protons in the nuclei of its atoms. If there are 10 electrons, then the fluorine atom has gained an electron and is now a negatively charged anion with a charge of 1-.
What is the element that has 8 electrons and 7 protons?
Any element with 7 protons would be Nitrogen
If element X has 91 protons how many electrons does it have?
If element X has 91 protons, it is element Protactinium (Pa) on the periodic table. In a neutral atom, the number of electrons equals the number of protons, so element X would also have 91 electrons.
An element has an atomic number of 30 how many protons and electrons are in a neutral atom of the element?
It will have 30 protons and 30 electrons if the atom is neutral.
what element 3 protons and 2 electrons?
If it has 2 protons, it has to be Helium. Helium atom has 2 electrons also, so if it has 3 electrons, it would be He^-
How many electrons does an element have if it has 17 protons and 18 neutrons?
If an element has 17 protons, it will also have 17 electrons since atoms are electrically neutral. Adding the number of neutrons (18) to the number of protons (17) gives us the mass number of the element, which in this case would be 35.
What would you get if you break an element into its smallest particles?
Protons and Electrons
If the nucleus had seventeen protons and nineteen neutrons how many electrons would the atom have?
The number of electrons in an atom is equal to the number of protons in the nucleus, which is 17 in this case. This ensures that the atom is electrically neutral, as the positive charge of the protons is balanced by the negative charge of the electrons.
What element has 51 protons and 52 electrons?
51 protons defines the element as antimony (Sb). It normally has 51 electrons, so with 52 electrons, it would be Sb with a 1- charge.
What group would a element synthesized with 115 protons group?
An element synthesized with 115 protons would belong to Group 15 (or Group 5A) in the periodic table. This group is known as the nitrogen group, consisting of elements such as nitrogen, phosphorus, arsenic, antimony, and bismuth.
What is the formula to get the number electrons?
First you would calculate the number of protons... the number of protons = the total mass number then the number of protons should = the nummber of electrons(unless their is a number in front of the element like +1) therefore= # of protons = # of electrons
What element has 12 electrons and 12 protons and 14 neutrons?
This would be magnesium, based on the number of protons. Since the protons is equal to the number of electrons it is a neutral atom. Given the number of protons in the atom, the isotope would be magnesium-26.
Can you use the mass number of an element to determine the number of electrons in an atom?
No, the mass number of an element is the sum of protons and neutrons in the nucleus. To determine the number of electrons, you would need to know the atomic number of the element, which is equal to the number of protons. Electrons in a neutral atom equal the number of protons.
