2- charge; 2 electrons
There are four electrons in a Beryllium atom. Hence the mono positive ion has only three electrons. Therefore the electron configuration is 1s2 2s1.
The electron configuration for a magnesium cation Mg2 plus is 1s2.2s2.2p6.
The difference between a beta plus and beta minus particle is the electrical charge. The charges are equal, but opposite. The beta minus particle is an electron with a negative charge, while the beta plus particle is an anti-electron or positron with a positive charge.
The charge on an electron is never equal to the charge on a neutron. An electron carries one negative charge and a neutron has no net charge.
The electron has a negative charge equal to -1.602 176 565(35) × 10-19 coulombs.
The sum of the superscript in an electron configuration is equal to the atomic number.
The sum of the superscript in an electron configuration is equal to the atomic number.
what does seven plus equal
2 plus 2 equal 4
The electron configuration for neutral Barium is [Xe] 6s2. Barium plus 2 means it has lost 2 electrons, so the electron configuration for Barium plus 2 would be [Xe].
8.00 plus 7.40 plus 68 is equal to 83.4.
71 plus 23 plus 49 is equal to 143.
There are four electrons in a Beryllium atom. Hence the mono positive ion has only three electrons. Therefore the electron configuration is 1s2 2s1.

The electron configuration for a magnesium cation Mg2 plus is 1s2.2s2.2p6.
4 plus 8 plus 12 plus 16 is equal to 40.
The difference between a beta plus and beta minus particle is the electrical charge. The charges are equal, but opposite. The beta minus particle is an electron with a negative charge, while the beta plus particle is an anti-electron or positron with a positive charge.
