they have both negitive and positive charge
a negative times a positive is a negative. plz recomend me.
Mn2+ has 25 electrons. Mn2+ means that the manganese atom has lost two electrons, resulting in a +2 charge. Mn is the symbol for manganese, which has an atomic number of 25, indicating that it normally has 25 electrons in its neutral state.
When two numbers with different signs are multiplied or divided, the answer is negative.
H+ has 1 proton and 0 electrons.Normal hydrogen has 1 proton and 1 electron. The number of protons always remains the same. The negative electron and the positive proton balance out the charge so that normal elemental hydrogen is neutral.H+ is the oxidized form of hydrogen. Its electron was taken away, so now it's left with 1 proton and 0 electrons, making its charge positive.H- is the reduced form of hydrogen. It has gained an electron, so now it has 1 positive proton and 2 negative electrons, making the charge equal to negative 1.
Yes, each oxygen atom in a water molecule carries a slight negative charge due to differences in electronegativity between oxygen and hydrogen. This partial negative charge on the oxygen atoms results in the overall polar nature of water molecules.
No. The sum of two negative numbers will always be a negative number. If, however, you multiply the numbers, their product will be positive.
An integer is any positive or negative whole number
12 electrons. Remember, electrons and protons must be balanced in charge; neutron number may vary.
no,a negative number cannot have a square root .it is made only for positive numbers .but,yes,negative numbers can be squared.
That little line sticking out on the left side of the '15' means it's a negative.
charge has negtive -2
The square root of positive number can be ether a matched set of positive or negative numbers. As an example the square root of 4 can be either (-2 x -2) or (+2 x +2)
