It should gain 2 electrons
Electrons are negatively charged particles, and they are negative in aluminum as well. Aluminum atoms have 13 protons (positive charge) in their nucleus and 13 electrons (negative charge) surrounding the nucleus.
The overall charge of an element is determined by the number of protons in the nucleus. Protons have a positive charge, while electrons have a negative charge. In a neutral atom, the number of protons is equal to the number of electrons, resulting in no overall charge.
An atom with 19 electrons has a charge of -19, since electrons carry a negative charge of -1 each. This negative charge is balanced by the protons in the nucleus, which have a positive charge of +19.
An electron has a negative charge. Also an ion in which there are more electrons than protons has a negative charge. Such an ion is called as anion.
Yes, selenium fluoride is a polar molecule since selenium is more electronegative than fluorine, leading to an uneven distribution of electrons and creating partial positive and negative charges within the molecule.
Selenium form anions.
The element with 2 electrons and a charge of -1 is helium. It typically has a charge of 0, but can gain an extra electron to have a -1 charge.
Electrons have a negative charge. When an element had more electrons than protons, it tends to have a negative charge.
Electrons charge is a negative
Selenium typically has 34 electrons in its neutral state. To determine the number of electrons in a selenium ion, you need to know the specific charge of the ion. For example, a selenium ion with a charge of +2 would have 32 electrons, while a selenium ion with a charge of -2 would have 36 electrons.
As an element oxygen is neutral, but it forms negative ions.
Electrons are negatively charged particles, and they are negative in aluminum as well. Aluminum atoms have 13 protons (positive charge) in their nucleus and 13 electrons (negative charge) surrounding the nucleus.
The charge of an ion formed by an element on the periodic table is determined by the number of electrons gained or lost by the element. This charge can be positive or negative, depending on whether the element loses or gains electrons.
The overall charge of an element is determined by the number of protons in the nucleus. Protons have a positive charge, while electrons have a negative charge. In a neutral atom, the number of protons is equal to the number of electrons, resulting in no overall charge.
If an element is missing one electron, which is defined as having a negative charge, then the element is a positively charged ion. If an element gains an extra electron, it will have a negative charge and be a negative ion. An element with an equal number of positively charged protons and negatively charged electrons is considered to be a neutral element (in other words, no charge). By the way, no charge for this answer!
An atom with 19 electrons has a charge of -19, since electrons carry a negative charge of -1 each. This negative charge is balanced by the protons in the nucleus, which have a positive charge of +19.
Electrons, which orbit the nucleus of an atom, have a negative charge.
