Many isotopes have 18 neutrons.
Each element in a period is in a transitional metal.
There is no element with 28 protons in group 4. I think you are getting confused with group 4 and PERIOD 4. In period 4, the element with 28 protons is Nickel.
Any element in the group 6 and period 3 (IUPAC version of periodic table).
No, the Neutrons vary with the element, in the same group as well, it depends on the isotope, like lithium for example, the most commonly occurring isotope has 4 neutrons, whereas sodium has 12
Germanium, belongs to period 4, group IVA (or group 14)
7th period because atomic size down the group increases. And Alkali Earth metals are found only in Group 1. The element is in Group 1 and period 7
The element in period two group eighteen is neon.
Each element in a period is in a transitional metal.
There is no element in period 3 group 6. The element at period 3, group 16 (called on very old periodic tables group VIA) is sulfur (S).
Each isotope of a chemical element has a different number of neutrons.
Group 0 Period 5
the element belongs to 4th period, 9th group, it is a d block element. the element is cobalt
Br (Bromine) is a period 4 element in the same group as F.
The element phosphorous (P) is located in group 15, period 2.
what element is found between period 2 and group 14
There is no such element.
Group 7 Period 5
