What do the periodic table symbols mean?
A typical periodic table has the element symbol e.g. C for carbon, W for tungsten, Pb for lead etc and often has the atomic number of the element (atomic number is the number of protons in the nucleus and therefore the number of electrons in a (neutral) metal atom.
What does the isotope of an element have?
An isotope of an element has a different number of Neutrons to the original element it came from. EG: Carbon( 11 neurtons) can go to carbon(12 Neutrons(
Which symbols represents represents atoms that are isotopes of each other?
A "superscript" number before the symbol for the element - eg. 11C 12C 13C 14C Denotes the four isotopes of the element Carbon. The superscript number is a count of the total number of "nucleons" (protons and neutrons) in the atomic nucleus of the atom. If you subtract the elements "atomic number" (which is the number of Protons that element has) from the Isotope (superscript) number you get the number of Neutrons in that isotope. From this you will be able to deduce that isotopes of elements are caused by a variation in the number of neutrons in an atom of an element.
If you have 2 atoms have the same number of protons but different number of neutrons what will they will have the same?
No, they will not be considered isotopes since isotopes are atoms of same element (therefore, have same number of protons). However, the types of atoms which have same atomic mass number but different no. of protons, they are called isobars. Eg:- Calcium and Argon = =
What does the atomic number of an element measure?
The atomic number is the number of protons in an atom. In an electrostatically neutral atom, ie not an ion, it is also the number of electrons. Every single atom of an element will have the same number of protons, eg. Carbon always has six protons. This also helps us to understand the layout of the electron in an atom. Carbon has six so it arranges them into an inner group of two and an outer group of four, meaning it can have up to four bonds. Hope this helps.
What do the horizontal rows on the periodic table represent?
Whereas the vertical columns on the periodic table are called "groups", and represent the number of electrons in an element's outermost electron shell (eg. group 2 elements have twoelectrons in their farthest energy level), the horizontal rows, known as "periods", refer to the number of energy shells surrounding the nucleus of an element.
Why are atomic masses written as averages?
elements exist in more than one form eg carbon 12 and carbon14
Represent a number with an integer?
an integer is a whole number eg 4, 58 not 3.2
What do the periodic table symbols mean?
A typical periodic table has the element symbol e.g. C for carbon, W for tungsten, Pb for lead etc and often has the atomic number of the element (atomic number is the number of protons in the nucleus and therefore the number of electrons in a (neutral) metal atom.
How is atomic mass mass number and atomic number calculated?
Allthese can NOT be calculated being physical properties of each specific element. They can be found in 'periodic tables' eg. by typing in the element name in a wikipedia-search
What does the isotope of an element have?
An isotope of an element has a different number of Neutrons to the original element it came from. EG: Carbon( 11 neurtons) can go to carbon(12 Neutrons(
Why i is used to represent square root of -1?
Because there is no "real" sqrt of a negative number, i is used as a symbol, eg sqrt -4 = 2i
What does the formula below represent?
CO2 + H2O + energy ? C6H12O6 Production of glucose in plants photosynthesis
What tells the number of protons in the nucleus of an atom of an element?
The atomic number of the element refers to the number of protons of an atom: all atoms of an element have this number of protons. A neutral atom of the element will have the same number of electrons.
What do you called in an element having the same atomic number but different atomic masses?
Isotopes. eg U235 and U238. Both Uranium, atomic number 92, bur different isotopes.
Which symbols represents represents atoms that are isotopes of each other?

Is the number 6220 a square number?
6220 is not a square number. The nearest number that is a square number would be 6241. A square number is when all the integers are written down, it could represent a square eg. 4 x 4 meaning that 16 is a square number.
