What is the sign of a cation?
Their sign is +, they have a positive charge.
How can you determine the sign and value of the charge on a polyatomic ion?
To determine the sign and value of the charge on a polyatomic ion, you need to look at the sum of the charges of the atoms that make up the ion. The charge is usually indicated in the chemical formula of the ion. If the ion has gained electrons, it will have a negative charge, and if it has lost electrons, it will have a positive charge.
Should a plus sign be used to indicate that a number is positive?
No. It is already indicated that it is positive without the positive sign on the number.
What is the the positive square root of a number indicated by the radical sign?
It is the principal square root.
What is the symbol for sodium with 11 protons and 10 electrons?
The symbol for sodium with 11 protons and 10 electrons is Na+. The plus sign indicates that the sodium atom has lost one electron, resulting in a positive charge.
When an object gains or loses electrons has it an electric charge?
That depends entirely on sign of the charge. If the object gains a positive charge, then that means the object as lost electrons, since electrons are negatively charge. If the charge is negative, then the object has gained electrons. It is also possible that the charge was created by a movement in protons, which are positively charged, in which case the object may not have lost or gained electrons.
Why do you use a plus sign for a protron?
Protons hold a positive sign, which is represented by the plus sign. Similarly, electrons hold a negative charge, which is represented by a negative sign.
Are electrons in group 2 lost or gained?
They are lost. If it has a plus sign beside the ion charge, that means the atom loses electrons. But if it has a negative sign for the ion charge, that means that the atom gains electrons.
How do you tell if an ion is positive or negative from a diagram?
In a diagram, positive ions are typically represented with a plus sign (+) next to the element symbol, while negative ions are represented with a negative sign (-). Additionally, positive ions usually have fewer electrons than protons, resulting in an overall positive charge, while negative ions have more electrons than protons, resulting in an overall negative charge.
What is the definition of real positive numbers?
A positive real number is any natural, integer, rational, or irrational number x such that x>0. In other words, the real numbers indicated by with or without positive sign (+) is known as Positive Real Number. Positive Real numbers are indicated by R+ mathematically.For example R+ = {1, 2, 3, 4, 5, .....}
Is Electrons a plus sign?
Protons! All protons are positively charged.
How many electrons are in the outer shell of aluminium?
3 electrons total. electrons is the number on the top right corner with the plus sign indicating that electrons are positive.
