Ca2+ is positively charged. Remember that an electron is a particle with negative charge; therefore, the element Calcium (Ca) has LOST 2 electrons in order to be positive 2.
When an atom has a charge of plus 1, it means that it has lost one electron, resulting in a positive charge. This atom is now called a cation due to its positive charge, and it will likely seek to gain an electron to achieve a stable electron configuration.
lose an electron, forms Na+, sodium with a charge of plus one.
Because atoms like to have a full outer shell - a sodium (1+) ion previously had 1 electron in it's outer shell, but it loses a (negatively charged) electron to gain a +1 charge. Chlorine, however, usually has 7 electrons in it's outer shell, but it gains a (negatively charged) electron to gain a -1 charge. Remember; gaining electrons = negative ions losing electrons=positive ions
The Alkaline metals (Group 1 metals). This is because they all have one valence electron and to become more stable by completing their outer shells, it is easier to lose 1 electron than it is to gain 7.
An electron has a negative charge of 1.6E-19 Coulombs. This will subtract from the net charge of an atom, so the net charge will be less, assuming that a negative charge is less than a positive charge.
Yes, a beta particle is either an electron or a positron. In beta decay, an electron is emitted (beta-minus decay), which has a negative charge, while a positron is emitted in beta-plus decay, which has a positive charge.
An electron plus an electron will repel each other due to their negative charges. This is because like charges repel each other according to the principles of electromagnetism.
An atom of potassium-41 becomes a potassium ion with a plus charge by losing one electron. Potassium-41 has 19 electrons in its neutral state, but when it loses one electron, it becomes a potassium ion (K+) with a plus charge and 18 electrons.

The electric charge of a proton is +1, and the electric charge of an electron is -1. Therefore, a particle containing two protons and one electron would have a total charge of +2 + (-1) = +1.
Sodium Na ions have a charge of +1 because they lose one electron to achieve a stable electron configuration. Sodium typically has 11 electrons, with 1 electron in its outermost shell. By losing this electron, it forms a stable cation with a +1 charge.
I predict that an ion of sodium will have a charge of plus one.
