B is Boron, and I think by the 'subscript number' you mean the atomic number of the element, 5.
3
The chemical formula will be A2B3.
3
The subscript is the number of atoms.Example: U3O8Uranium octoxide has 3 uranium atoms and 8 oxygen atoms.
Compound would look like this. A2B3 A = 6 total valance ( two atoms ) B = 6 total valance ( three atoms )
its atomic numberthe number of neutrons
If Element B Has 9 As The Atomic Number And 19 As The Mass Number What is The Answer how many protons does it have?
B) atomic number
A mapping is a relationship between two sets. Given sets A and B (which need not be different) a mapping allocates an element of B to each element of A.
Boron, symbol B
Atomic number of an element tell you how many protons and how many electrons there are in that element.... e.g. B-Boron Atomic number=5 Number of protons=5 Number of electrons=5
Sum(All elements in B) - Sum(All elements in A)
No, the proton number decides, whether they are of the same element. In this case, they are isobars.
distinguish extra element in two arrays
Boron is a non meta element. Atomic number of it is 5.
The elements that make up a compound and the exact number of atoms of each element in a unit of the compound are shown in the compound's formula unit for an ionic compound) or molecular formula (for a covalently bonded compound). These characteristics of the compound are show by:use in the formula of at least one* instance of the atomic symbol for each element in the compound; and,for each element with more than one atom present in a unit of the compound, also more than one instance of the symbol in the formula and/or a subscript number after the atomic symbol.The subscript numbers are chosen so that the sum of:(a) all the explicit subscripts for each element symbol for the same element; plus(b) the number 1 for each appearance in the formula of the same atomic symbol without any explicit subscript,shows the exact number of atoms of that element in a unit of the compound.________________In order to show differences in chemical bonding, a symbol for the same element is conventionally written more than once in the formulas for some compounds, such as ammonium nitrate, with formula NH4NO3, and acetic acid, with formula CH3COOH.
If every element of B is contained in C, then B is a subset of C. If every element of B is contained in C and B is not the same as C, then B is a proper subset of C.The cardinal number of a set is the number of elements in the set.In this case, C has 8 elements, so B has at most 7 elements.
Boron is a non metal element. Atomic number of it is 5.
The number is 84.Assign the digits in the number the letters a and b.GIVEN: a + b = 12GIVEN: a = 2bSolve for b, then solve for a.2b + b = 123b = 12b = 4a = 2(4) = 8
b. the atomic number is constant. The mass number is not constant because there are isotopes of an element that have the same number of protons but different number of neutrons. Likewise, there are isotopes of the same element with different atomic weights.
Presuming that Element B has valency of 2, then the resulting compound will most probably be 2 atoms of element A for every 3 atoms of element B.
The number of valence electrons
Atomic number 5: boron (B)
#includemain(){int a;print f("enter the element of a");scan f("%d",&a);if(a^2==4)print f("it is a perfect square");elseprint f("not a square");getch();}Its not working.......... I am done the program#include#includevoid main(){int a,b;clrscr();printf("Enter the num");scanf("%d",&a);b=sqrt(a);if((b*b)==a)printf("The given number %d is perfect square",a);elseprintf("The given number is not a perfect square");getch();}
B is the symbol for which element?Boron
