What element has 99 electrons?
The element with 99 electrons is einsteinium (Es), which has an atomic number of 99. It is a synthetic element that was first discovered as a result of nuclear tests in 1952.
How many valence electrons would an element with atomic number 56 have?
The element with atomic number 56 is barium, a group 2 alkaline earth metal. Its atoms have two valence electrons in the 6s sublevel.
How do you tell how many electrons are in an element?
You can determine the number of electrons in an element by looking at its atomic number on the periodic table. The atomic number represents the number of protons and electrons in a neutral atom of that element. For example, carbon has an atomic number of 6, so it has 6 electrons.
What element that is a metal has 28 electrons?
The element with atomic number 28 is Nickel (Ni). It is a transition metal in period 4 of the Periodic Table. It is the first element in the Nickel family. It has 28 electrons in 4 shells with 2 electrons in the outer shell.
What eleme has 2 electrons in the first shell and 8 in the second and 6 in the third?
What element has 2 electrons in the first shell and 8 in the second and 6 in the third
How to find the total electron in element?
To find the total number of electrons in an element, first you need to look up the element's atomic number. That number tells you how many protons are in the element. Then, look up the net charge of the element. The number of protons subtracted by the elements net charge will give you the number of its electrons.
What is the maximum number of electrons an element can have on the first level?
3
What is the number of electrons of Be?

How many electrons and protons are in an element with an atomic?
put it in your mind! The Atomic number. is number of protons, While The Mass number. is number of protons and electrons. when you subtract both get the number of electrons and this for any element but not all elements have same atomic numbers or mass and Rutherford First discover "transmutation" from element to other element which determine by their atomic and mass numbers.
How do you find the number of electrons in element?
The Atomic Number of the element is equal to the number of electrons. Also, the number of protons is also equal to the Atomic number; so the number of protons and electrons in any given element is the same!
If an element has 9 electrons how many should be in the second shell?
There should be seven in the second shell and two in the first. The element in question is fluorine, which has the atomic number 9, the same as the number of its protons and electrons.
How many valence electrons would an element with atomic number 56 have?
The element with atomic number 56 is barium, a group 2 alkaline earth metal. Its atoms have two valence electrons in the 6s sublevel.
How do you tell how many electrons are in an element?
You can determine the number of electrons in an element by looking at its atomic number on the periodic table. The atomic number represents the number of protons and electrons in a neutral atom of that element. For example, carbon has an atomic number of 6, so it has 6 electrons.
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 is the 28?
The element with atomic number 28 is Nickel (Ni). It is a transition metal in period 4 of the Periodic Table. It is the first element in the Nickel family. It has 28 electrons in 4 shells with 2 electrons in the outer shell.
